INVITED SESSION PAPERS Recently, wearable wireless devices have been widely used in our daily life. Also, implantable wireless devices have been developed and become available for various monitoring as well as identification systems. Unlike conventional wireless devices, wearable or implantable devices are used on or in the human body. In this sense, body-centric wireless communications (BCWCs) have become a very active area of research. On the other hand, radio-frequency or microwave medical devices used for cancer treatment and surgical operation have completely different functions. However, they are used on or in the human body. In terms of antennas installed inside the devices, such medical devices have lots of similarities to BCWCs. To design properly and to make the best use of specific antennas for different wireless devices, it is important to treat them as human-centric antennas. In general, the problem of an antenna placed on or in the human body can be treated as a so-called "boundary value problem" where the human body is considered as a lossy medium. However, in reality and simplicity, an individual case is treated appropriately in a specific manner by numerical simulation such as the FDTD technique. The paper introduces a few examples of wearable antennas as well as implantable antennas developed and tested in our laboratory. In addition, the paper describes some challenges of human-centric antennas.

INVITED SESSION PAPERS This talk will present the latest work on microwave and mm-wave phased arrays at UCSD and in the world. The talk shows that one can build affordable phased arrays using low-cost silicon-RFICs (RF integrated circuits), and these phased-arrays are now being considered to replace the movable reflector for satellite communications on airplanes, ships and moving platforms. The silicon-based phased-arrays are also being considered for terrestrial 5G communication systems, to be employed first to replace the "last mile" for internet and video delivery to homes, and then for high-speed links between base-stations and a mobile user. In this context, phased-array systems achieving Gbps at 300 meters and 1000 meters will be presented. It will be shown that low-cost phased-arrays have changed the way we think about our future communication systems from SATCOM to 5G.

REGULAR SESSION PAPERS A coil is integrated inside an implanted antenna in order to support inductive charging. The implanted antenna has been designed for wireless data telemetry at 402MHz region and radiating wireless charging at 915MHz. The antenna-coil system is embedded into a three layer canonical model of human arm. In the inductive charging case an external transmitting coil is considered while in the radiating charging scenario a dipole is implemented. Several simulations are carried out for the antenna-coil system. While radiating charging seems to be more efficient inductive charging can be used as a complimentary solution since they both can coexist Quang-Trung Luu 1448603 UMR 8507 CNRS, CentraleSupélec, UPMC, Université Paris-Sud France 0 Stavros Koulouridis 386627 University of Patras Greece 0 Antoine M Diet 280213 Paris Saclay - Université Paris Sud ( GeePs UMR 8507 - IUT de Cachan ) France 0 Yann Le Bihan 1447840 GEEPS France 0 Lionel Pichon 1284443 CentraleSupélec - CNRS - Université Paris Sud & GeePs Laboratory France 0 14:20 14:40 1570317857 B_A01 Bio Ant.2 UWB On-body Slotted Patch Antennas for In-Body Communications 1. REGULAR SESSION PAPERS One of the most relevant challenges of next generation in-body devices consists in enhancing the medical applications of wireless networks qualitatively. The current standard does not allow high data rate wireless connections between implanted nodes. UWB systems have been considered as a potential candidate for future in-body devices. To establish a proper link within UWB, antenna matching should be ensured within the frequency range of interest. Besides, a good wave penetration trough the biological tissues is totally essential. In this work, several UWB on-body slotted patch antenna models are assessed and discussed. According to the propagation medium, the on-body antenna designs have been miniaturized and optimized taking into account the dielectric properties of human tissues. After a thorough comparison between antenna models, an optimized model has been manufactured. Finally, the performance of the optimized antenna prototype has been assessed.

REGULAR SESSION PAPERS The wireless link between an implant and an off-body gateway may be difficult to secure due to the fact that electromagnetic waves quickly attenuate through human tissues. The signal strength may be quite weak by the time the waves reach the skin. In order to address this problem, a digitally assisted repeater antenna has been designed to be located outside of the patient's body, and act as a relay between the implant and the off-body gateway. The radiation pattern is switched between two modes depending on the link formed: in-body or off-body link. With an overall size of 30x30x3.15mm, the antenna operates in the 2.4GHz ISM band. The repeater is aimed to be used to secure wireless communications with a hip implant. Therefore, for a typical depth of such an implant of 4cm, the repeater has been shown to enable a decrease of 40dB in the transmit power level. Sema Dumanli 398203 Toshiba Research Europe Ltd.

REGULAR SESSION PAPERS A compact planar monopole antenna backed by an electromagnetic bandgap (EBG) structure is presented. The antenna is conformal to the human body and is intended for wearable applications in wireless body area networks. It operates at 2.45 GHz, and is fabricated on a 68mm by 38mm by 1.57mm semi-flexible substrate. The performance of the antenna does not degrade with structural bends along both of its axes, thus making it robust to structural deformation. In all cases it maintains a fractional impedance bandwidth in the range of 5%, with a gain ranging from 6.3 to 6.7 dBi. The antenna performance is also insensitive to the antenna location on the human body. For placements of the antenna on the arm, chest and leg, it maintained a 5% impedance bandwidth with radiation efficiencies above 70% and an average gain of 7.3 dBi. Marco A.

REGULAR SESSION PAPERS In this paper, a flexible directional monopole antenna for wearable head imaging system for stroke detection is presented. To ensure better flexibility for wearable applications, a very thin flexible PET substrate, Melinex 339 with thickness of 75µm is utilized. The size of the antenna is 70mm × 30mm. An array of 8 antennae are arranged in elliptical configuration to follow a human head contour. The antennae operate at frequency of 1.3GHz to 3.5GHz which would provide sufficient penetration and resolution. These antennae were designed and optimized to work in close proximity with human head. An investigation on mutual coupling between neighboring antennae when in close proximity with artificial human head and on free space is carried out via CST Microwave Studio and experimentation. Specific Absorption Rate (SAR) with different transmitted power level are simulated to ensure that the electromagnetic wave absorbed by human head is below the safety limit.

REGULAR SESSION PAPERS In this paper the performance of TM21 resonance-mode circular patch antennas embroidered with different stitching patterns is discussed and compared. The goal is to investigate the difference in the performance when the antenna is embroidered with stitches following the antenna current paths as opposed to some simple patterns such as horizontal and vertical ones. This creates an alternative solution for embroidering prototypes of wearable antennas with complicated current distributions. The results reveal that by embroidering the antenna in line with the complex TM21 current distribution a good monopole-like radiation pattern is achieved, which is close to an etched copper prototype's used as the reference. However, with a dense horizontal stitching pattern an acceptable monopole-like radiation pattern can also be achieved with quite good gain and efficiency. While simplifying the embroidery process, the use of the simple horizontal pattern with high density suffers from high cross-polarization and thread consumption as compromises. Roy B. V. B.

CONVENED SESSION PAPERS Recent developments in inductive wireless power transfer (WPT) mean that the technology has reached a point where powering small drones has become feasible. Fundamentally, drones can only carry limited payloads and thus require light-weight WPT receiver solutions. The key to achieving light weight is operating the WPT system at high frequency: this allows both the coils and the electronics to achieve very high power densities. When operated in the MHz region, the WPT coils can be manufactured without the need for ferrite, because the low coupling factor can be offset by very high coil Q factors. To make efficient MHz power conversion circuits, wide band-gap semiconductors, including SiC and GaN have provided a step change. For powering a drone, these devices are integrated into soft-switching resonant inverter and rectifier topologies and are able to operate efficiently at tens of MHz.

CONVENED SESSION PAPERS Wireless energy harvesting from ambient electromagnetic fields is becoming an emerging technology that can be exploited as a power source for many low power electronic devices. A number of key challenges are identified but the optimum design of rectennas for ambient WEH is very challenging. This paper presents a review on recent progress in multiband and broadband rectennas for WEH and wireless power transfer and introduces the latest research on this topic at the University of Liverpool, UK. In addition to the existing technologies, we have developed a number of novel techniques to develop rectennas with a simple structure, a broad bandwidth and an improved RF-DC conversion efficiency. Moreover, our rectennas can achieve consistent performance for a dynamic input power level or a wide load impedance range. The state-of-the-art technologies presented in this paper could have a great impact on the future development of rectennas for many related applications.

CONVENED SESSION PAPERS RF-powered devices equipped with general-purpose microcontrollers face energy limitation constraints for performing arbitrarily complex sensing/computation tasks. While richer capabilities such as image capture and processing would enable many new RF-powered use-cases, this energy limitation narrows the application space. Enabling richer sensing tasks has two main challenges: efficiently retaining harvested energy, and storing/communicating large quantity of sensor data. This paper reviews the WISPCam design, an RF-powered programmable camera. WISPCam integrates an off-the-shelf VGA camera which is a rich sensor example energy and data wise. The paper also presents an ultra-low power scheme that is able to provide periodic updates on charge state of the device before enough energy has been accumulated for image capture. This paper presents a novel data storage and bi-directional communication scheme that enables reliable transfer of complete images to an RFID reader application even when packets are lost or the device runs out of energy.

CONVENED SESSION PAPERS For reducing the weight of a satellite, an internal wireless system of satellite is proposed in a previous study. It is a system that can communicate between the subsystems of a satellite by carrying wireless communication modules. In this paper, we propose a complete internal wireless system of satellite with microwave wireless power transmission technology, and designed a 5.8 GHz highly efficiency rectifier circuit based charge pump circuit, and introduced a class-F load. We compared the rectifying efficiency of single shunt rectifier and charge pump rectifier theoretically, the conclusion is that they should have the same conversion efficiency, and this result are verified by experiment. The conversion efficiency increase to 78 % at 30 mW in the simulation, and obtained about 71 % conversion efficiency in the experiment. In addition, the output voltage is higher than 5 V at optimum load.

A wireless connectivity system is used to provide high-throughput and reliable wireless connectivity between moving trains and static base-stations installed along the tracks in all scenarios. The system should be designed to meet the following set of unique requirements for the transportation segment:High throughput and stable performance (low latency and jitter) to support variety of services as high definition (HD video), VoIP Telephony and high capacity Internet access In this paper RADWIN explains some topics on how to achieve the above.

CONVENED SESSION PAPERS In this paper, channel measurements for the 2.6 GHz band in railway environments are presented. The measurements have been carried out in the subway of Madrid in different environments (tunnel, station and open air scenarios). An intra-consist link for a future wireless Train Control and Management System (TCMS) has been measured for two types of trains, a continuous train and a non-continuous train. The results in these two trains allow checking the impact of the separation between cars in this type of links and the influence of the environment. Wideband and narrowband measurements have been carried out, and Power Delay Profile (PDP), delay spread and pathloss have been extracted and are shown in this paper. Results are useful for the design of communications systems inside train cars.

CONVENED SESSION PAPERS Nowadays, rail traffic is expected to evolve into a new era of ``smart rail mobility", which requires a seamless high-data rate wireless connectivity with up to dozens of GHz bandwidth. Such a huge bandwidth requirement motivates the exploration of the underutilized millimeter (mm) wave and Terahertz (THz) bands. In this paper, six scenario modules for mm wave and THz train-to-infrastructure channels are defined and constructed for the first time. All the main objects, such as tracks, stations, crossing bridges, tunnels, cuttings, barriers, pylons, buildings, vegetation, traffic signs, billboards, trains, etc., are modeled according to the typical geometries and materials in reality. Ray-tracing simulations show that these objects indeed influence mm wave channel properties, and therefore, they can even play a more important role in the channels at higher frequency bands -- THz. The modules presented in this paper are constructed through abstracting commonness of typical rail traffic scenarios. Ke Guan 438121 Beijing Jiaotong University P.R.

CONVENED SESSION PAPERS During the beginning of the 2000s, amidst the boom of metamaterials, EBG structures and AMC surfaces, the authors of the paper had the privilege of working with Professor Kildal on revisiting the concept of soft and hard surfaces, which was already established for a decade at that time. These belong to the category of artificial surfaces with the ability of providing unexpected boundary conditions in a given frequency range. In parallel with metamaterials, we present a summary of some of the applications that were developed, among them hard waveguides or invisible struts. Meeting Per-Simon has changed our lives for better forever.We are now established researchers and we met him at the beginning of our carriers. We have been very close friends and collaborators with him all along these years. We feel now like orphans and our lives will never be the same without his supportive friendship and inspiration.

CONVENED SESSION PAPERS In the late 1990´s Professor Per-Simon Kildal got the idea that reverberation chambers could be used for characterizing small antennas and mobile devices. Many thought the idea was crazy but he was persistent and worked hard to realize his dream to build a small chamber that could be used by the wireless industry. This paper gives a short history of the research at Chalmers and the creation of the company Bluetest that both were instrumental for realizing the dream.

CONVENED SESSION PAPERS UWB systems have been proposed as a candidate for the next generation of in-body applications. In order to perform reliable UWB channel measurements, implantable antennas should work in the propagation medium properly. To assess the UWB channel performance, in-body antenna matching should be assured. Besides, an omnidirectional radiation pattern in order to communicate with a sensor array located around the body should be achieved. This paper is devoted to the analysis of the UWB in- body channel when using an antenna miniaturization procedure that maintains its omnidirectional radiation pattern as well as its operation bandwidth. For that, an UWB monopole antenna with circular patch is directly miniaturized and optimized considering the human muscle tissue. To assess the impact of antenna miniaturization, the results of the channel propagation measurement campaign obtained with the miniaturized antenna are compared with those obtained from a larger UWB monopole in a previous measurement campaign.

CONVENED SESSION PAPERS As increased requirements for much high speed and capacity telecommunications, frequency bands of wireless communications become higher such as millimeter wave or terahertz wave. In these high frequency bands, beam foaming is employed to gain stable connectivity. On-body body area network is one of fascinate application of these high capacity frequency bands. However, directions of on-body antennas largely fluctuates and shadowing frequently occurs due to human movements. In this paper, variation of antenna directions and shadowing of on-body propagation during human walk movement is investigated. As a result, range of antenna rotation and shadowing rate, which can be used future system design of high frequency body area networks, is clarified.

CONVENED SESSION PAPERS In this paper, we investigate the characteristics of the composite fading observed in non-line-of-sight (NLOS) off-body communications channels using the $\eta$-$\mu$/inverse gamma distribution. We use a number of different datasets obtained from NLOS off-body measurements which have been performed in a range of different environments at 5.8 GHz and 60 GHz. In all cases, the bodyworn node was positioned on the front-central chest region of an adult male. It is shown that the $\eta$-$\mu$/inverse gamma model provides an excellent fit to the measurement data for all of the considered cases. Using the Akaike information criterion (AIC), we have compared the -/inverse gamma model with other composite and non-composite fading models associated with the NLOS channel conditions. The AIC results confirm that the $\eta$-$\mu$/inverse gamma model was the most likely model to have been responsible for generating the channel data from the set of candidates which were considered.

CONVENED SESSION PAPERS This paper presents an analysis of the polarisation characteristics for the channel in dynamic off-body communications, and an empirical channel model, based on measurements performed at 2.45 GHz in an office environment. Body presence and propagation conditions have a strong influence on signal depolarisation. The model assumes three components for the total path loss: mean path loss, represented by a log-distance function with a path loss exponent of 1.71, Lognormal-distributed shadowing fading, and Nakagami-distributed multipath fading. The Nakagami Distribution shows a trend towards the Rice one in the co-polarised and the Rayleigh one in the cross-polarised channels.

CONVENED SESSION PAPERS With the advent of the Internet of Things, body-worn sensor nodes are continuously becoming more important. In case of bio-medical, rescue-worker or military applications sensitive data are often transmitted, requiring the need for encryption. Body-worn sensor nodes are generally employed in quickly varying channel conditions due to body movement. The radio-communication channel between such nodes is however reciprocal, allowing the extraction of an array of similar channel measurements at both ends of the link. These data can be used to build equal encryption keys at both link ends. This paper studies the practical performance of an enhanced channel-based key generation system with a very short round-trip delay. Measurements were performed using the new system and the results of the enhanced key generation are evaluated. Although the performance is slightly increased thanks to the shorter round-trip delay, the accuracy of the signal level detector still imposes limits.

CONVENED SESSION PAPERS Transmitarray antennas with dual-band and dual-polarization capabilities are studied here numerically. The antennas are designed based on linearly-polarized unit-cells working at Ka-band for satellite applications. The unit-cells include two printed patches and a connecting via; a 180° phase shift is obtained by rotating one of the patches. The dual-band property is achieved by interleaving unit-cells dedicated to each band, and two different polarizations in each band. The numerical results demonstrate the working principles of dual-band dual-polarized transmitarrays.

CONVENED SESSION PAPERS The paper presents a dual circular polarization unit cell for realizing a reflectarray that synthesizes two independent patterns based on the polarization of the incident field. To this end, a thin polarizer, which converts incident circularly polarized (CP) waves into orthogonal linearly polarized (LP) waves, is cascaded with a dual-linear-polarization (DLP) reflectarray. The reflectarray then applies the required reflection phases to the LP waves. The proposed antenna system is structured by placing the polarizer adjacent to the DLP reflectarray. Numerical simulations are arranged to assess the performance and ability of a 20 GHz unit cell design in providing high polarization purity and independent reflection phases for orthogonal CP waves. Enclosing 4×4 polarizer cells as small as 0.14λ×0.14λ, the unit cell features an overall thickness of ~1λ and lateral dimensions of 0.55λ×0.55λ.

CONVENED SESSION PAPERS An investigation of curved contoured beam reflectarrays with reusable surface for multiple coverages is presented. The main advantage of curved reflectarrays over shaped reflectors is that they allow the possibility of reusing a standard parabolic mold for multiple missions. To demonstrate this, two curved reflectarrays are designed using the direct optimization technique to fulfill the requirements of two contoured beam missions in both transmit and receive frequency bands for dual linear polarization. The two reflectarrays use the same curved surface, f/D, dimension, and feed, and by changing the reflectarray element pattern, two completely different coverages can be produced while maintaining a performance that is comparable to that of the shaped reflector.

CONVENED SESSION PAPERS Two dual reflectarray antennas able to provide an European coverage and beam scanning over 8º respectively have been presented. An accurate technique has been proposed for the analysis of dual-reflectarray antennas, which takes into account the angle of incidence of the field impinging on main reflectarray cells. Two 50-cm antenna demonstrators with the same geometry have been manufactured and measured in a compact range. The measured radiation patterns for the contoured beam antenna are in good concordance with the simulations and practically fulfill the coverage requirements with a cross-polar discrimination better than 25 dB in the frequency band 12.975 GHZ- 14.25 GHz. The measured radiation patterns of the beam scanning antenna are in good agreement with the simulations for transmit and receive frequency bands in Ku-band with a cross-polar discrimination better than 30 dB within a scanning range of +4°.

CONVENED SESSION PAPERS A 1.1-m reflectarray antenna has been designed, manufactured and tested to fulfil the requirements of a satellite antenna in Ku-band to provide a South American coverage in Tx and Rx. The reflectarray cells consist of four dipoles for each polarization in two dielectric layers, which were selected because of their simplicity and high performance. The dipole dimensions are optimized in all the reflectarray cells to accomplish the prescribed radiation patterns, by iteratively calling an analysis routine based on MoM-SD and local periodicity. The measured radiation patterns of the manufactured antenna have been satisfactorily compared with simulations and with a 3-layer reflectarray previously designed for the same mission. Jose A.

CONVENED SESSION PAPERS The problem of efficiently and effectively compute the response (i.e., reflection coefficients) of next-generation reflectarray elements with wide number of degrees-of-freedom is addressed in this work. Towards this end, a machine learning- based approach based on advanced Kriging strategies is exploited (instead of classical full-wave solvers) in order to predict the response of complex unit cells of interest for the design of high-performance reflectarrays. Preliminary numerical results aimed at comparing the accuracy and efficiency of the proposed methodology with respect to standard full-wave approaches are illustrated.

CONVENED SESSION PAPERS When an electromagnetic wave illuminates on an engineered surface, a phase discontinuity occurs, which leads to the generalized law of reflection and refraction. In this paper, the limit of the phase discontinuity on a single-layer surface is revealed for both co- and cross-polarized fields. Full 360° phase shift range of the cross-polarized field is achieved by using a single-layer metal-only defected square ring slot element. Then, an X-band reflect-transmit-array (RTA) antenna with zero-thickness is designed, fabricated, and measured. It is only composed of a metallic sheet with 420 mm side length, spatially fed by a corrugated horn. Well-defined pencil beams are formed at both broadsides, and the measured gain is 25.5 dBi at 10 GHz with 15% 1-dB gain bandwidth. The proposed zero-thickness RTA exhibits distinguishable advantages of being ultra-thin, lightweight, and low-cost without using dielectric substrates. Ruyuan Deng 1166071 Tsinghua University P.R.

CONVENED SESSION PAPERS A reflectarray antenna composed of more than 87000 single-crystal silicon resonators on a gold ground plane is experimentally demonstrated to achieve efficient beam focusing at 1 THz. The functionality of the reflectarray as a collimator is also verified by the principle of antenna reciprocity. Because of the low-loss and nondispersive nature of high-resistivity silicon in the submillimeter regime, the losses of the reflectarray are negligible, a very desirable feature at such frequencies. Reflectarrays based on dielectric resonator antennas (DRA) have been relatively unexplored in the terahertz range, mainly because of the challenging fabrication process.

The first one is based on the Levenberg-Marquardt Algorithm (LMA) while the second technique is based on the generalized Intersection Approach framework using the LMA as backward projector. As full-wave analysis technique, a spectral domain Method of Moments based on local periodicity is employed. Two test cases are provided to show the capabilities and limitations of the techniques. The optimization is carried out in different computers to assess their scalability properties. In addition, the convergence of both techniques is compared in terms of number of iterations and results achieved.

REGULAR SESSION PAPERS In this paper, we present validation of a method for constructing a virtual omnidirectional antenna in the azimuth plane. The virtual omnidirectional antenna utilizes a combination of data from directive horn antennas. The aim is to utilize the high gain of the horn antenna to improve the dynamic range of channel sounding measurements conducted in the centimeter and millimeter wave bands. The resulting complex impulse response from the virtual omnidirectional antenna is used to find the power-delay-profile (PDP). This is then compared to measurements conducted at the same time using a real omnidirectional antenna. The validation shows that the synthesized omnidirectional is capable of predicting main components and the slope of the PDP. Further, it is shown that by choosing angular sampling steps corresponding to the half power beam width (HPBW) of the used antenna similar power levels can be achieved.

REGULAR SESSION PAPERS Ray-based and hybrid propagation models are today considered as valuable solutions to fulfill 5G wireless channel modeling requirements. They are a complement or alternative to the stochastic approaches when link-level and system-level simulations deal with millimeter-wave (mmWave), ultra-dense deployment and/or large antenna arrays. The present article proposes an extension of an urban ray-based model for the assessment of a 60-GHz outdoor small-cell network. The multi-paths are predicted from interactions with the static environment, but also with randomly-positioned vehicles and user-bodies. Both the vehicles and the user-body generate ray-path blockage, and (in case of the vehicle) new propagation paths. This sometimes affects the cell selection or beam orientation, and significantly changes the received signal strength and inter-cell interference. The user-body blockage is illustrated on two simple use cases (single-cell and two-cell scenarios). Then the impact of both stochastic components is assessed through the performance simulation of a whole mmWave small-cell network.

REGULAR SESSION PAPERS If a channel is frequency dependent then Uncorrelated Scattering (US) (a narrow-band assumption) don't hold. This has a significant impact at the considered channel modeling methodology as delay and angular dispersion of waves can no longer be studied independently because the small scale fading of individual multipath components become correlated. In this paper, we investigate the frequency dependence of the 30 GHz millimeter-Wave (mmWave) Ultra-Wide band (UWB) channel. Our indoor small lecture room measured channel results show that both delay and angular spreads vary significantly for different frequencies within a measured UWB channel. This is due to different interactions with objects in the environment due to significant difference in the comparative wavelengths. Therefore, we stress that mmWave-UWB channel modeling methodology must take into account the frequency dependence of channel parameters. In order to support its significance, we have also provided an evidence from mmWave system architecture point of view.

REGULAR SESSION PAPERS In this paper, we propose a novel method to mitigate the strong shadowing effect a nearby finger has on the antenna of a handheld communications device operating at 60 GHz, by introducing reflectors on the device. When the finger is located at the distance of 3 mm of the antenna, it causes strong shadowing and the far-field radiation attenuation behind the finger is 25-34 dB. In this paper, we show that a parabolic reflector ``collar" that is placed around the antenna array can significantly reduce the shadowing in the far-field. With the collar, the far-field radiation behind the finger is improved by 19-25 dB, making the array usable even when covered by a finger. The effect of reflector size and location is studied.

In underground mines, the effects of the complete blockage of line-of-sight (LOS) by miners are unavoidable. This paper presents an experimental study for assessing NLOS miner shadowing effects (MSE) on data transmission. Thus, two separate measurement scenarios are performed with and without the presence of a miner in the channel i.e, LOS, and NLOS MSE. Result show that, LOS underground mines are Ricean channels with a K-factor of 9.3 dB. However, the presence of a miner restrains K-factor to 3.6 dB. Furthermore, the experimental channel bit error rate (BER) are validated theoretically. Thus, confirming that under MSE scenario, an additional SNR of more than 13 dB is required to yield a BER of 10-4 as compared to LOS case.

REGULAR SESSION PAPERS In this paper a novel design of an UE (User Equipment) antenna for the 60-GHz band is presented. The antenna was realized on LTCC A6M-E substrate to ease a later integration with the RF-chipset on a single module. To satisfy the requirement of a relative bandwidth of 15% an electrically thick substrate was utilized, which unfortunately leads to an undesired excitation of surface waves. A suppression of these dielectric modes was achieved by employing a cancellation technique of excited surface waves. The proposed antenna consists of two parallel fed aperture coupled microstrip patch antennas. The S-parameter and radiation pattern results (simulation and measurement) are presented and are used to verify the antenna design. The manufactured antenna exhibits a -10dB impedance bandwidth of more than 9GHz, a Half Power Beam Width (HPBW) greater than 60° and a realized gain of more than 5.5dBi over the bandwidth.

REGULAR SESSION PAPERS A key limitation of high gain planar microstrip antenna arrays relies in the high loss of the feeding network. In this paper, we propose an innovative way to solve this issue by feeding a microstrip patch antenna by an aperture coupled dielectric filled waveguide. Using a low loss dielectric, we managed to achieve a low loss and compact waveguide. The proposed antenna supports both V band (57-66 GHz) and E band (71-86 GHz) applications with a matching better than -10 dB and a broadside gain higher than 8 dBi. Simulated gain is notably higher than classical microstrip antenna gain [1], which is related to the high efficiency (> 90%) of the proposed antenna architecture. This innovative antenna could be used as a unit-cell for the design of a compact and high efficiency large antenna array, targeting backhaul communications at V and E bands.

REGULAR SESSION PAPERS This paper presents a new topology for a wire-grid antenna array which operates at 60 GHz. The array consists of ten λg/2 dipole radiators connected via non-radiating connectors. Both radiators and connectors are placed on top of narrow silicon walls. The antenna is fed with a coplanar microstrip lines placed at the other side of the wafer and is connected with its feeding transmission lines using through-silicon-vias. The antenna is optimized for two cases: using high- and low-resistivity silicon substrates. The former has better radiation characteristics while the later is more compatible with the driving electronic circuits. The antenna has high directivity, reasonable bandwidth and high polarization purity.

REGULAR SESSION PAPERS In this paper, a Dielectric Image Line (DIL) based Millimeter-wave (mm-wave) Multiple-Input-Multiple-Output (MIMO) antenna is proposed in Ka-band (27-40 GHz). This MIMO antenna system uses two DIL tapered antennas having their radiation patterns in opposite directions. To keep low field correlation, the antenna elements are kept λ0 distance apart. The proposed antenna exhibits 12 GHz (28-40 GHz) impedance bandwidth with approximately constant radiation patterns and at least 38 dB isolation between ports. The simulated peak gain at both the ports are around 12 dBi at center frequency (33.5 GHz). To evaluate the MIMO performance, the Envelop Correlation Coefficient (ECC) and Diversity Gain (DG) have also been calculated for the proposed antenna.

Results on extinction cross section, linear degree of polarization and other scattering quantities of interest are presented. We also show how those results are interesting in different domains where scattering phenomena are studied thanks to the scale invariance properties of the Maxwell equations using the so called microwave analogy.

REGULAR SESSION PAPERS In this paper, a simple electromagnetic model for wind turbine's backscattering is proposed. The wind turbine is modeled as a linear structure made of three rotating wires on which an electromagnetic fields impinges. Since a wind turbine is much bigger than typical radar range resolution cells, just a small part of it is involved in the backscattering for a single resolution cell. An analysis of the micro-Doppler features for each range cell involving the wind turbine is then proposed. The models are both compared and validated using real data acquired with PARSAX radar. The main features obtained from these models can be used to understand the backscattering mechanisms for a wind turbine and for developing of clutter mitigation algorithms.

REGULAR SESSION PAPERS Flight inspection of radio-based terrestrial navigation systems is crucial for sufficient accuracy. Especially in proximity of wind turbines (WT), flight inspections must be carried out. This causes problems that hinder the usage of conventional aircraft. To solve this problem, unmanned aerial systems (UAS), such as multicopters, are a promising approach. Beside the solution of the clearance problem, they also provide further benefits in terms of cost effectiveness and flexibility. Since commercial off-the-shelf (COTS) test receivers exceed the UAS's loading capabilities, we developed a weight- and size-optimized test receiver that can compete with full-compliance measurement COTS devices. This has been achieved by focusing on the demands regarding carrier frequency and bandwidth of the system under test (SUT). In this paper we describe the RF front end for the reception of the forward scatter emitted by the airport surveillance radar (ASR) and show the first measurement results.

REGULAR SESSION PAPERS The current Air Traffic Management (ATM) uses a combination of several radar system. However, the conventional Primary Surveillance Radar (PSR) have a high cost of the operation in comparison with usage. Recently, Multi-Static Primary Surveillance Radar (MSPSR) has attracted interest from the civil aviation research field. The MSPSR system use not only the conventional radar signals but also other radio waves, such as Digital Terrestrial Television Broadcasting (DTTB). In this paper we described the experimental results of aircraft detecting by using DTTB signals and the potential of the aircraft detection by proposed method.

REGULAR SESSION PAPERS A novel procedure is presented for the evaluation of matrix elements of the tensor Green function with Rao-Wilton- Glisson basis functions appearing in surface integral equations in electromagnetics. The procedure,contitutres the generalization of our previous result to non-planar geometries, reduces four- dimensional surface integrals with singular integrands to line integrals over triangle edges with regular integrands. The main advantage of the derived expressions is that they offer simplicity and easily controllable accuracy achieved at a computational cost significantly lower than for previously considered techniques, in particular the conventional singularity subtraction method.

REGULAR SESSION PAPERS The spectral domain Method of Moments (MoM) is customarily used in the analysis of multilayered periodic structures. In this paper a hybrid MoM is introduced for the analysis of multilayered periodic structures containing sets of dipoles at two metallization levels. In the hybrid MoM the matrix entries involving basis functions of dipoles at different metallization levels are computed in the spectral domain. However, the matrix entries involving basis functions at the same metallization level are computed in the spatial domain. The implemented hybrid MoM is applied to the design of multilayered reflectarray antennas made of dipoles under the local periodicity assumption. Thanks to the use of interpolated expressions for the periodic spatial Green's functions in terms of both coordinates and incidence angles, the CPU time required by the hybrid MoM in the design of the antennas is around twenty times faster than that required by the spectral domain MoM.

REGULAR SESSION PAPERS The Poggio-Miller-Chan-Harrington-Wu-Tsai (PMCHWT) integral equation is widely used in the scattering analysis of dielectric bodies. The RWG set is normally adopted to expand the electric and magnetic currents in the Method of Moments (MoM) discretization of the PMCHWT formulation. This set preserves normal continuity across edges in the expansion of currents. However, in the analysis of composite objects, the imposition of such continuity constraint around junctions, where several regions intersect, becomes convoluted. We present a new nonconforming discretization of the PMCHWT formulation so that currents are expanded with no continuity constraint across edges. This becomes well-suited for the analysis of composite objects or nonconformal meshes, where some adjacent facets have no common edges. We show RCS results where the nonconforming PMCHWT implementation, facet-oriented, shows similar or better accuracy as the conventional approach, edge-oriented, for a given degree of meshing.

REGULAR SESSION PAPERS In this paper we propose a scheme to treat, as a whole, the 4-D reaction integrals appearing in the Method of Moments. The surface divergence theorem is twice applied directly in the physical space domain, thus eliminating restrictions to well-shaped, touching elements required by mapping to an angle-distorting normalized coordinate system together with an appropriate integration reordering. The resulting 4-D surface integral is expressed as two radial integrals plus two contour integrals over source and observation domain boundaries. The radial integrals significantly smooth the kernel, and the resulting contour integrals are further regularized for efficient numerical evaluation.

REGULAR SESSION PAPERS The Locally corrected Nyström (LCN) method is used for current reconstruction on the surface of microwave boards and antennas. A relationship is established between LCN and RWG method of moment (MoM) for this application to enforce current continuity. This approach allows designers to find, characterize, and address the cause of a design failure in a microwave board or an antenna under test. The advantage of this method over the conventional method of moment (MoM) is that as a point-based approach efficiency can be enhanced in its acceleration with the multilevel fast multipole algorithm (MLFM).

REGULAR SESSION PAPERS Universidad Politécnica de Madrid (UPM) is participating in the Alphasat propagation experiment by measuring the copolar level of the Q-Band beacon at 39.4 GHz since April 2014. In this paper the results of the first two complete years of measurements (until March 2016) are presented with regards to excess and total attenuation. The reference level is calculated on an event-by-event basis in the first case, and obtained from GNSS-based gas attenuation in the second one. The results reflect the variability of the meteorological conditions in the climate of Madrid, with strong differences among the months of the year and between the two years, reinforcing the need of having long-term propagation experiments to capture all the variability of the propagation effects.

REGULAR SESSION PAPERS Scintillations affect the propagated signal with an unwanted aleatory oscillation at the receiver. A first analysis of data acquired from Alphasat Q-band receiver station, located in Spino d'Adda (Italy), is performed. Correlation between meteorological measurements at the ground and measured scintillation from the Q-band beacon receiver (i.e., fluctuation of the received electromagnetic field) is investigated. Radiosounding data from north Italy station of "Milano Linate" have been collected for the entire year 2015 and used to calculate the refractive index structure constant. Subsequently the amplitude scintillation variance is derived through the use of the Rytov model on the slant path. Results obtained using the scintillation model are compared with measured data from Alphasat beacon receiver, investigating the statistical correlation in clear air condition between simulated and measured data.

REGULAR SESSION PAPERS The performance of both a recent rainfall rate model and the inter-annual variability prediction method proposed by the International Telecommunication Union has been assessed taking advantage of the availability of 16 years of rain gauge data. The above rainfall rate model produces as well monthly rainfall rate distributions that have been compared with the experimental monthly distributions achieving good results. The procedure proposed in the ITU variability prediction method has been adapted to test its usefulness to estimate monthly and seasonal variability. In some cases, fair agreement has been found between estimated and experimental variability.

REGULAR SESSION PAPERS Simultaneous measurements of tropospheric scintillation on three different satellite beacons at Ka-band are analyzed. The links have elevation angles of 3.3, 21.2 and 22 degrees. Corner frequency of scintillation is used to calculate the transverse wind speed on each of the links and this is compared with the predictions from a numerical weather model. Results for the two links with higher elevation angle show good agreement with each other as well as with the model data. For the link with elevation angle of 3.3 degrees good match with model data is achieved only when theory applicable for outer scale of turbulence smaller than the Fresnel zone is used. Significant changes in scintillation corner frequency during rain events are also observed for the 3.3 degree link. The results indicate that scintillation at very low elevation angles can be composed of different phenomena, leading among others, to different frequency dependence.

REGULAR SESSION PAPERS The SatComs performance employing frequency-reuse schemes to improve the spectral efficiency is degraded due to the depolarization-induced interference originated by hydrometeors present along the propagation path. Two models are able to account for all contributions: one enables the prediction of the first-order statistics (CDF) of cross-polarization discrimination (XPD), and another enables the prediction of the relationship between XPD and co-polar attenuation (CPA). The second was developed for the V-band and so, it requires independent validation and extension to other frequency-bands. The predictions provided by the first are usually converted on the corresponding XPD-CPA relationship using the long-term first-order statistics of rain attenuation, (wrongly) considering that the equiprobability base applies. Using 8 years of measurements both models are tested, a new regarding the XPD-CPA relationship is proposed for the Ka-band and another base to be employed on the conversion of the CDF of XPD on the XPD-CPA relationship is investigated.

REGULAR SESSION PAPERS Drop Size Distributions (DSDs) measured with an optical disdrometer in Madrid during 5 years are used to derive the copolar attenuation (CPA) and cross polarization discrimination (XPD) at 19.7 and 39.4 GHz. A full wave Method of Moments (MoM) is utilized to calculate specific attenuation and phase rotation through a realistic scattering raindrop model for large raindrops. The best-fit parameters are compared with those given in the ITU-R Recommendation P.618-12. Significant differences are observed for vertical and horizontal polarizations at 19.7 and 39.4 GHz. In this paper, yearly variability of XPD and fitting parameters are presented.

REGULAR SESSION PAPERS For the last decades satellite communication systems have been moving towards higher and higher frequencies; rain attenuation along the Earth-satellite path can be an important limiting factor for the system availability, especially in tropical regions where rain events can be particularly intense. One of the possible countermeasures is site diversity. In this paper we evaluate the performance of small-scale, multiple-site diversity systems, through simulations performed on rain-rate time series gathered by four rain gauges located in the equatorial city of Guayaquil, Ecuador. The results show a considerable improvement in terms of performance of the system.

REGULAR SESSION PAPERS The employment of optical frequencies in satellite communication systems has been proposed in order to cover the huge needs for capacity in the next decade. The reliable design and the prediction of the performance of optical satellite links need accurate channel modeling in the form of time series generators. Considering cloud free line- of-sight (CFLOS) satellite links, turbulence effects on the received signal contain the dominant fading mechanism. In this paper a methodology for generating time series of irradiance due to turbulence for optical satellite uplink scenario is presented. The time series generator takes advantage of the use of Stochastic Differential Equations SDEs driven by Brownian motion. The methodology is applied for several hypothetical links in Greece for the generation of first order statistics of received power. Moreover small scale and large scale diversity techniques are evaluated for the mitigation of turbulence effects.

REGULAR SESSION PAPERS We consider the differential microwave imaging for continuous monitoring of hemorrhagic brain strokes where our aim is to determine the change of bleeding in sequential time frames. The scattered electromagnetic field is measured in two different time steps, and the difference in the scattered field is used as the data of the inversion scheme. The imaging is performed via contrast source inversion. However, since the data of the inversion scheme consists of the difference of the scattered field measurements, the algorithm produces a differential contrast function instead of a complete reconstruction. This function carries information about the difference in the electromagnetic parameters of the brain, that is the relative size of the blood region, between two measurements. The numerical simulations with a realistic head model demonstrate that the method is capable of detecting changes in multiple blood regions, and provides information about the locations and the types of these changes.

REGULAR SESSION PAPERS A hybrid technique using Digital Breast Tomosynthesis and Microwave Tomography shows promise for improved contrast with respect to conventional breast imaging modalities. A healthy background field is modeled using a Finite Difference solver with prior geometry given by Digital Breast Tomosynthesis. This background field is subtracted from the measurements to isolate the anomalous portion of the measured signal which is due to the carcinoma. The healthy background geometry used in this simulation is obtained using a characteristic relationship between the mass attenuation coefficient (measured in X-ray images) of healthy tissue and the complex dielectric constant. This relationship can be computed using gradient descent. However, the computationally demanding nature of this inverse problem makes it less desirable for real clinical applications. Proposed herein is an algorithm which uses Born approximation on alternate iterations to decrease computational demand. Preliminary 2D numerical experiments in realistic media show this adjustment decreases the computation time.

REGULAR SESSION PAPERS The knowledge of the complex Radar Cross Section (RCS) of the human body in ultra-wide band can fully describe the breathing activity. In this paper, we investigate the time domain RCS so as to analyze the backscattered signal from the human body, for further respiratory monitoring in any aspect angle. The time domain RCS measurements are first calibrated with the monostatic radar measurement of a metallic sphere. Subsequently, the RCS of a human body phantom is measured over the full 0-360o angle, azimuth range, allowing to put forward the creeping wave around the body. Finally, we measure the RCS of a human person and its temporal variation, also in various aspect angles. The results, which show a mixture between breathing and other body movements, are valuable inputs for respiratory monitoring in various body postures.

REGULAR SESSION PAPERS Nanosized devices operating inside the human body open up new prospects in the healthcare domain. In vivo wireless nanosensor networks (iWNSNs) will result in a plethora of applications ranging from intrabody health-monitoring to drug delivery systems. With the development of miniature plasmonic signal sources, antennas and detectors, wireless communications among intrabody nanodevices will expectedly be enabled in the Terahertz Band (0.1-10 THz). This result motivates the analysis of the phenomena affecting the propagation of electromagnetic signals inside the human body. In this paper, a rigorous channel model for intrabody communication in iWNSNs is developed. The total path loss is computed by taking into account the combined effect of the spreading of the propagating wave, molecular absorption from human tissues, as well as scattering from both small and large body particles. The overall attenuation model of intrabody THz propagation facilitates the accurate design and practical deployment of iWNSNs.

Afterwards, the refractive index distribution of the optically transformed lens is realized by changing the height of the pins in a bed of nails configuration. The complete Luneburg lens is simulated in CST Microwave Studio and the results demonstrate that the lens has 8-16 GHz bandwidth.

These devices can find potential applications in novel antenna concepts. Jianjia Yi 1176203 Xidian University P.R.

CONVENED SESSION PAPERS A general design of metalenses for N-beam emissions is proposed based on transformation optics. A linear transformation mapping is adopted to achieve the homogeneous characterization of the transforming medium, which is therefore easy to be fabricated compared with previously designs limited by inhomogeneity based on transformation optics. To verify the theoretical design, a four-beam antenna constructed with ultrathin, homogenous and uniaxial anisotropic metalens is designed, fabricated and measured. It is shown that the realized gain of the four-beam antenna is increased by 6 dB compared with the single dipole source, while working frequency and relative bandwidth are kept unchanged. The measured far-field pattern verifies theoretical design procedure. Kuang Zhang 1357268 Harbin Institute of Technology P.R. China 1 Guohui Yang 1233285 Harbin Institute of Technology P.R.

CONVENED SESSION PAPERS CubeSats are positioned to play a key role in Earth Science, wherein multiple copies of the same RADAR instrument are launched in desirable formations, allowing for the measurement of atmospheric processes over a short, evolutionary timescale. To achieve this goal, such CubeSats require a high gain antenna that fits in a highly constrained volume. This paper presents a novel mesh deployable Ka-band antenna design that folds in a 1.5U (10×10×15cm3) stowage volume suitable for 6U (10×20×30cm3) class CubeSats. Considering all aspects of the deployable mesh reflector antenna including the feed, detailed simulations and measurements show that 42.6 dBi gain and 52% aperture efficiency is achievable at 35.75GHz. The mechanical deployment mechanism and associated challenges are also described, as they are critical components of a deployable CubeSat antenna. Both solid and mesh prototype antennas have been developed and measurement results show excellent agreement with simulations.

CONVENED SESSION PAPERS The paper considers a backhaul network for Ka-band. In this band, antenna arrays must employ large number of elements with appropriate beamforming techniques to combat the severe path loss. The goal of this paper is to analyze massive antenna arrays under realistic considerations for the use in terrestrial backhaul links. This analysis addresses practical issues from the implementation point of view such as 3D array geometry, the minimum number of radiating elements needed to fulfill link budget requirements in backhaul links, distribution of radiating elements in a 3D array geometry and influence of realistic antenna patterns on beamforming capabilities of such arrays. The results indicate that a realistic backhaul scenario may require antenna arrays containing thousands of radiating elements. Selected simulation examples show that polarimetric beamforming is required in realistic scenarios especially when radiating elements do not have good cross polarization discrimination.

CONVENED SESSION PAPERS Future 5G backhaul networks in dense small cell deployments will require high gain antennas with beam- and null-steering capabilities. In this framework this paper analyzes the null-steering capabilities of reflectarray antennas, as a low cost alternative to traditional antenna arrays. In particular, a random search algorithm is used to show that null-steering can be performed even with 1-bit reflectarrays, but that the synthesized null-depth and width is much more sensitive to aperture phase errors than the main beam gain. Multi-feed reflectarrays are then proposed to overcome this sensitivity but at the expense of higher system complexity and cost.

CONVENED SESSION PAPERS This paper evaluates different analog-digital beamforming solutions for future spectrum sharing mm-wave scenarios. In contrast to sub-GHz multiantenna schemes where all-digital solutions provide an excellent performance-cost trade-off, in the mm-wave bands where a very large number of antennas is required, all-digital designs cannot be deployed due to their cost and complexity. In order to solve this problem, sub-array solutions are conceived where a reduced number of radiofrequency chains are simultaneously connected to different antennas through an analog beamforming network formed by phase shifters (i.e. with no amplitude control). Different connectivity solutions are evaluated; namely, full-connected, localized and interleaved considering that either the phase shifters have full resolution or only one control bit. As reported in the paper, while for the full resolution case the same performance is obtained for all three connectivity schemes, in case the phase shifters have one control bit, substantial differences show up.

CONVENED SESSION PAPERS In the present paper we evaluate the performance of a hybrid digital/analog multi-beam beam-forming architecture with polarization and delay compensation using time reversal (TR). Double-directional, ultra wideband dual-polarized channel measurements at 70 GHz in a conference room have been used to emulate the channel. The use of multiple beams to mitigate human shadowing has been evaluated and the temporal and spatial focusing of time-reversal to reduce inter-user interference.

REGULAR SESSION PAPERS The performance of multiuser multiple input multiple output (MIMO) downlink communication system is degraded under the assumption of rapid movement of user terminals with a certain speed. Though several methods have been proposed to improve this situation, they consume extra-degrees of freedom for the extension of the zero forcing (ZF) area and/or heavy computational load for the frequent update of weights. This paper presents a low computational design approach based on block diagonalization consuming degrees of freedom smaller than or equal to the minimum required value, where only a subset of transmit weights are updated according to linearly extrapolated channel keeping the zero forcing condition as possible. Computer simulations exhibit that the proposed approach can always show good performance if the adequate weight update parameters are chosen.

REGULAR SESSION PAPERS In order to achieve high accuracy in measuring sidelobes and/or nulls in antenna patterns, it is necessary to use a test system with very high dynamic range. For several years, commercially available antenna measurement receivers have offered a dynamic range as high as 135dB for such applications. This dynamic range has been made possible, in part, by a simple correlator in the receiver's DSP chain. In a previous paper, noise-free signal models were developed and analyzed to demonstrate the correlator's ability to reduce carrier frequency offset (CFO) and local oscillator (LO) phase noise to offer the fidelity of test signal necessary to achieve extremely high dynamic ranges of up to 135dB. Building on those models, this paper models the effects of thermal noise and analyzes situations where the correlator works well and where it negatively impacts performance.

REGULAR SESSION PAPERS Inverse equivalent-source algorithms for antenna field transformations are particularly powerful and robust if they work with directive sources that radiate primarily from the source region towards the field observation locations. Such directive behaviour can for example be achieved by employing an additional integral equation that explicitly imposes a null-field condition (known also as a Love condition) in the original source region of the antenna. An approximate null-field condition can be achieved in the form of an impedance-boundary condition, which is also known as the combined-source condition. In this work, the combined-source condition is utilized in a weak form, and the directivity of the expansion sources is further increased by shifting the source points into complex space. This inverse source algorithm is formulated and used for near-field to farfield transformations of measured antenna fields. The results are discussed and compared to those achieved with the corresponding strong-form algorithm. Thomas F.

REGULAR SESSION PAPERS One-port reflection calibration is a widely used technique for RF and microwave VNA measurements in a broad range of applications including on-wafer chip testing, production testing, and microwave imaging. Recent developments in the field of antenna tuning components lead to advanced, highly stable MEMS-based variable capacitors. In this study we present the use of an antenna tuning integrated circuit (IC) for realizing a compact and fast transfer standard for one-port calibration. In contrast to traditional Short-Open-Load methods a new workflow that uses different capacitance states was developed. Together with least-squared-error solving this leads to improved calibration performance. Verification against metrology grade standards showed agreement of less than -45 dB vector difference. In addition, an estimation of the expected S-parameter error due to temperature deviations was performed. The new calibration workflow can be used in applications where multiple ports need to be calibrated fast and accurate.

REGULAR SESSION PAPERS In this paper, the problem of NFC/RFID technology frontend performance verification is addressed. To make this technology succeeded, it is necessary to test conformance, acceptance, compliance, consistency and interoperability of NFC/contactless infrastructure. Industry bodies such as EMVCo is developing and maintaining programs to ensure device conformance, acceptance, compliance, consistency, and interoperability. Thus, a Test Bench Simulator is proposed, based on a Computer Aided Design tool, which allows flexible, fast and accurate verification strategy for NFC technology designs against complete test plans that are fully compliant with EMVCo NFC/contactless experimental specifications. To verify the proposed design, simulations are carried out and results are compared to the results of particular measurements done by the EMVCo laboratories. All results show a pretty good matching with EMVCo standard. Additionally, in this paper, simulation is conducted using full-wave 3D FEM EM Simulator.

REGULAR SESSION PAPERS Implantable medical devices are becoming smaller by the day, with more efficient electronics and smaller power demands. Nevertheless, there are some applications in which power demands are inherently high, and solutions must be found to keep the devices as small as possible. In this paper, we propose an antenna to be used in wirelessly powering a focal brain cooling implant based on a Peltier device. This antenna is designed in order to act as a heatsink for the device with the goal of minimizing its final volume, therefore design constrains such as size limitations and geometry restrictions are considered.

REGULAR SESSION PAPERS Energy harvesting from ambient RF signals is feasible, particularly from the GSM bands such as 900MHz,1800MHz and the 3G band at 2.1GHz. This requires a wideband receive antenna which can cover all these bands with decent gain performance and an omnidirectional radiation pattern. In this work, a novel Cantor fractal antenna has been designed which fulfills the above mentioned performance requirements. Antenna has been realized through a combination of 3D inkjet printing of plastic substrate and 2D inkjet printing of metallic nanoparticles based ink. The stable impedance and radiation performance of the antenna over a bandwidth of 0.8GHz to 2.2GHz (93 %) shows the feasibility of its employment in wide band energy harvesting applications.

REGULAR SESSION PAPERS This paper investigates reactance compensation method to eliminate the impact of cross-coupling in single frequency inductive power transfer (IPT) system with arbitrary number of receivers. Receiver-side resonance loses its optimality in multiple receiver scenarios under the existence of significant cross-coupling among receivers. Therefore, the resonant capacitances are added with compensatory reactances, whose values are analytically optimized for maximizing efficiency based on N-port network model. Cross-coupling eliminating effect of our method is verified by numerical analysis. The results also indicates that as the coupling between the transmitter and the receivers becomes weaker, the impact of cross-coupling becomes more severe, and because of that the reactance compensation becomes more effective.

The modeling takes into consideration the external source supplying the communication between tags, radiating characteristics of tag antennas, and reception system aspects. Performance results are expressed in terms of Bit Error Rate (BER) with respect to the distance between the tags and the position of the energy source relative to the position of the two tags.

REGULAR SESSION PAPERS This paper presents a system to measure the bulk dielectric properties of a non-metallic target. It is intended as a first step towards a multi-antenna pixel type, imaging system using the same principles. The system, based on the free-space method, comprises two Ultra-Wide Band (UWB) antennas submerged in a tank of lossy background liquid. Data is collected by submerging the Object Under Test (OUT) between the antennas and performing a transmission measurement. The dielectric properties of the OUT are recovered using a UWB inverse scattering algorithm. This employs a 3D Electro-Magnetic (EM) simulation of the system that uses a static conductivity material model. The system is calibrated by means of a measurement without the OUT present. Dielectric properties of a range of materials are recovered to within 10 % of the ground truth. Results suggest that a pixel based imaging system may be viable.

REGULAR SESSION PAPERS A broadband coaxial line to rectangular waveguide transition for a microwave tomography sensor is presented. It consists of two parts: a coaxial line to double ridged waveguide transition and a double ridged to rectangular waveguide transformer. The transition is well matched (reflection coefficient below -10 dB) and has a low insertion loss (below 3 dB) in a wide frequency range from approximately 0.85 GHz to 4.4 GHz. Due to the symmetric design of the double ridged waveguide, a large single mode propagation bandwidth (0.6 GHz to 3.2 GHz) and a good higher order mode suppression (greater than 10 dB above 3.2 GHz) is achieved. The transition design is described in detail, analyzed by 3D electromagnetic field simulations, and validated by measurements.

REGULAR SESSION PAPERS Ultra-wideband (UWB) radar imaging has attracted attention for use in security and intelligent transportation system (ITS) applications. Conventional UWB Doppler interferometry is an effective way to obtain high-resolution images while using a simple radar system. However, this method produces ghost images when multiple closely-spaced human targets are present. To resolve this problem, we propose a new technique that combines UWB Doppler interferometry with an adaptive beamforming method called estimation of signal parameters via rotational invariance techniques (ESPRIT). We also propose a tracking and separation algorithm that uses the k-nearest neighbor method. Through a combination of numerical simulations and measurements, we demonstrate the remarkable performance improvement that can be achieved using our proposed method. The proposed method can separate multiple humans with a root-mean-square error of 5.2 cm, which makes its accuracy 1.9 times higher than that of the conventional method.

REGULAR SESSION PAPERS A modified bow-tie antenna consisting of two semicircle flares fed by a tapered microstrip line is described. Such design allows avoiding separate impedance transformers and baluns that are often poorly matched over the wide frequency band of operation resulting in considerable late-time ringing. The tapered microstrip line using one of the antenna flares as ground plane is used to transform 50 Ohm impedance of the feeding cable to the antenna impedance of around 100 Ohm. The antenna performance was tested experimentally using a concrete member made of heavy density concrete with a metal rod inserted near its center. For the sake of comparison, two other antennas designed for the same frequency band, namely tapered-slot Vivaldi antenna and conventional bow-tie antenna with impedance transformer have been tested in the same scenario.

REGULAR SESSION PAPERS The standard Yee grid, though simple and robust, is not well suited to modelling anisotropic media. In contrast, the Lebedev grid is well suited, but is computationally more expensive. A methodology is presented to use classical Yee grid in isotropic regions and take advantage of Lebedev method as a subgridded region for anisotropic materials only. Two methods to couple the two regions are proposed and described in detail. The proposed methods show low reflection in a scenario where a normally incident planewave hits Yee-Lebedev interface. Also, the two techniques are shown to be both accurate and stable.

In this work, an efficient and accurate interpolation scheme has been combined to the standard FaFFA algorithm implementation further reducing the complexity of the computation.

REGULAR SESSION PAPERS In this work, a stable marching-on-in-time method is presented to obtain scattering response from arbitrary wire structures illuminated by a Gaussian plane wave directly in the time domain. Contrary to all the available time domain algorithms till now, the present procedure is also capable of handling multiple excitations in a trivial manner. The new procedure is based on the conventional method of moments and utilizes standard pulse functions for expansion of space and time variables. The testing procedure is accomplished by collocation procedure. The numerical results obtained using the new procedure are validated by comparing with data obtained from frequency domain solution and performing inverse discrete Fourier transform.

REGULAR SESSION PAPERS Surface impedance absorbing boundary (SIABC) has a comparable absorbing performance compared to CPML, but requires a sufficient long distance between the boundary and the scatter. In this paper, we focus on this issue and introduce the non-uniform SIABC. Non-uniform SIABC archives a similar absorbing performance as the uniform SIABC at a same distance, while the number of the air buffer cells is much smaller. Therefore, it is possible for us to make it more efficient relative to uniform SIABC or CPML. An example of a patch antenna is discussed to explore the accuracy and efficiency of non-uniform SIABC. We also compare the memory usage for uniform SIABC, non-uniform SIABC, and 10-layers CPML. All the results indicate that non-uniform SIABC requires much less memory, needs much less time for simulations, which makes it a potential of being one of the most popular ABCs in FDTD method.

REGULAR SESSION PAPERS Availability of fast yet reliable replacement models is essential to reduce the computational cost of antenna design process. Unfortunately, conventional approximation (or data-driven) modeling is not well suited for modeling of highly nonlinear responses of antenna structures, especially for larger number of geometry parameters. In this work, we propose a novel approach where the region of surrogate model validity is restricted to a manifold spanned by several reference designs corresponding to antenna optimized for various operating frequencies and dielectric permittivity of the substrate material. This allows us to focus the modeling process in the region that only contains designs that are close-to-optimum from the point of view of the aforementioned operating/material criteria. Rigorous analytical formulation of the technique is supported by a case study of a ring slot antenna. Considerable reduction of the number of training points compared to conventional modeling methods is demonstrated.

REGULAR SESSION PAPERS Wave propagation in a general dispersive chiral media is examined by a direct finite difference time domain (FDTD) technique. Using convolutional integrals directly in time domain without use of transformation techniques such as Z-and Mobius transformations, wave field decomposition is the main idea to drive the FDTD formulation. Time domain permittivity, permeability, and chirality of dispersive materials are found from their frequency domain expressions. These time domain models are used in convolutional terms to model wave propagation in dispersive chiral media. The co- and cross-polarized reflected and transmitted waves from a chiral slab illuminated by a normally incident plane wave are investigated. The results have a good agreement with previous ones using Z-transformation technique. Reza Mohammadi-Baghaee 1445754 School of ECE, University of Tehran, Tehran, Iran.

CONVENED SESSION PAPERS The rapid growth of wireless data drives the development of new technologies. We have here in mind the current works on 5G standardization, wireless backhaul developments in V/E Band as well as low orbit mobile satellite service development in Ku band. For all those communication systems, the availability of high performance and cost effective antenna is key. To address this need, fundamental enablers lie in manufacturing technologies able to handle complex 3D shape while providing at the same time fast and low cost prototyping as well as the ability to support volume production. This paper illustrates how 3D printing and digital manufacturing technologies might help to develop innovative and cost effective antenna solutions in order to address new business challenges.

CONVENED SESSION PAPERS Purely passive, mechanically steered waveguide-fed horn arrays are good candidates to satisfy the current need for low-to-medium-profile antennas for mobile user terminals for SATCOM applications. In this work, a unique waveguide feed architecture is proposed, which enables the realization of grating lobe-free, wideband, low-profile waveguide-fed horn arrays operating with dual circular polarization. The realization of such structures using 3D printing is investigated, showing the promise of such techniques in terms of design flexibility. To demonstrate the potential of the proposed waveguide array architecture combined with 3D printing, an 8-by-8 antenna array operating in the 20 GHz SATCOM Ka band has been developed and is presented. This antenna exhibits an aperture efficiency of about 80% over a relative bandwidth larger than 10%.

CONVENED SESSION PAPERS In this paper an additive manufactured (AM) W-band monolithic feed chain is presented. The feed chain, which consists of a corrugated horn antenna and a turnstile orthomode transducer (OMT), operates over the entire W-band (75 − 110 GHz) and fulfills typical EM specifications for space applications (RL > 20 dB, IL < 1 dB and Xpol < −30 dB). Both the OMT and the horn have been designed by exploiting the design freedom offered by AM, but also taking into account its specific technological constraints. The presented W-band design can be straightforwardly scaled to V-band.

CONVENED SESSION PAPERS This paper presents a circularly-polarized dual-band antenna for Ka-band satellite communications which operates simultaneously in both civil and military downlink (17.7-21.2 GHz) and uplink (27.5-31 GHz) bands. The antenna is composed of a metallic ridged cavity that is perforated with a crossed-slot. This cavity is excited in sequential rotation through four feeding coaxial cables, thus producing circular polarization (CP). The required feed distribution is obtained by a dedicated beam-forming network (BFN) able to provide phases to generate right/left-handed CP in the downlink/uplink-bands, respectively. The prototype of the antenna cavity is 3D printed basing on stereolithography (SLA), while the BFN is realized in printed circuit technology. Good agreement is obtained between theoretical and measured results, thereby validating the antenna concept and confirming the strong potential of SLA to conceive compact RF components. Joana S.

CONVENED SESSION PAPERS Uncertainty quantification has become a hot topic in computational sciences in the last decade. Indeed computer models (a.k.a simulators) are becoming more and more complex and demanding, yet the knowledge of the input parameters to feed into the model is usually limited. Based on the available data and possibly expert knowledge, parameters are represented by random variables. Of crucial interest is the propagation of the uncertainties through the simulator so as to estimate statistics of the quantities of interest. Monte Carlo simulation, a popular technique based on random number simulation, is unaffordable in practice when each simulator run takes minutes to hours. In this contribution we shortly review recent techniques to bypass Monte Carlo simulation, namely surrogate models. The basics of polynomial chaos expansions and low-rank tensor approximations are given together with hints on how to derive the statistics of interest, namely moments, sensitivity indices or probabilities of failure.

CONVENED SESSION PAPERS Electromagnetic (EM) structures such as antennas, resonators, are widely used in EM communication systems. It is not uncommon to find that the performance characteristics of these structures are not as expected because of the uncertainties introduced during the manufacturing process. These uncertainties may arise, for instance, from variations of the dimensions of the device or its material properties, e.g., permittivity and permeability. A statistical tool based on the use of the Polynomial Chaos Expansion (PCE) technique is proposed in this work. The results of investigation of two EM structures, namely an E-shaped patch antenna and a split-ring resonator (SRR), are presented as examples. The results confirm that the variability of the design parameters must be taken into account while designing such structures. A sensitivity analysis is also performed in order to determine the most influential parameters that affect the performance of the studied structures.

CONVENED SESSION PAPERS This contribution aims to assess the sensitivity of the time domain response of a straight thin electrode buried in a lossy half-space. The issue is of crucial importance in many fields including electrical engineering (e.g. ground penetrating radar purposes, lightning protection for electrical settlements). Indeed, such systems are subject to more and more complex radiating coupling, mostly due to the variability of input parameters. An alternative approach to classical Sobol' indices is proposed here, jointly with an advanced analytical resolution of Pocklington integro-differential equation.

CONVENED SESSION PAPERS This paper is focused on the statistical analysis of the human indoor exposure induced by a WLAN source (often named "box") located close to the walls of a room of 3*4 m2. The exposure is firstly assessed by using a hybridize method combining the spherical wave description and the FDTD numerical method. A scenario, where the anatomical model is located in unknowing room position and the source is near to the wall but in an unknowing position is analyzed. Due to the variability of this scenario, the entire possible configurations cannot be calculated with the FDTD. A statistical method based on Polynomial Chaos is therefore discussed and used to build a surrogate model allowing to assess the exposure distribution.

Principal component regression was used to fit the model using six anatomical and dielectric factors. The results demonstrated that the method could effectively reduce the dimension of the variables and the fitted model for one frequency was applicable to other frequencies.

A sensitivity analysis was carried out in order to assess the influence of these parameters on EM field exposure. Results have highlighted the importance of received power density from base stations to the issue of global exposure induced by a macro LTE network for an entire population in an urban area.

CONVENED SESSION PAPERS A stochastic framework is proposed to evaluate the effect of random effects on the overall performance of wireless links. A generalized polynomial chaos expansion is leveraged to relate the uncertainties in antenna geometry, orientation and position to the figures of merit characterizing the link. The stochastic testing procedure is proposed as a more efficient alternative to stochastic collocation, for a large number of random variables. The non-intrusive statistical framework is applied to evaluate the uncertainty on the efficiency of a wireless power transfer system.

CONVENED SESSION PAPERS This paper proposes to add diffuse scattering correlation to Effective Roughness (ER) models used in ray tracing. Diffuse scattering correlation is modeled by phase evolution models including a deterministic part and a correlated (random) part. The deterministic part is dependent on the distance variations between the moving terminal and each ER tile, and the correlated part is related to the angular variations. The predicted narrowband radio channels by ray tracing with proposed diffuse scattering correlation are compared with those obtained by applying a reference physical optics approach, in terms of the Doppler properties over spatial frequency.

REGULAR SESSION PAPERS This paper describes the ongoing site-diversity experiment, consisting of three beacon receiver stations in Slovenia and one station in Austria. All the four stations are identical in configuration and are measuring the 20.2 GHz beacon signal, transmitted from the ASTRA 3B geostationary satellite. The stations were gradually deployed in the years 2014 and 2015. The measured attenuation time series and joint attenuation time series are obtained and statistically analysed. The results are presented in two parts: a) for one full year of collected data from the three Slovenian stations, and b) for seven months of recently collected measurement data in the four-site constellation, including the Austrian station. The results confirm the benefits of site diversity system in terms of significant attenuation reduction. They are compared also to the existing ITU-R and the recently proposed Gaussian copula prediction models and the agreement is satisfactory.

CONVENED SESSION PAPERS The effect of loss tangent variation is properly faced in this work for the accurate design of microwave sensors to be applied in the non-invasive monitoring of blood glucose. Bio-antenna optimization is performed by accurately considering the complex permittivity variation of the biological radiation medium. At this purpose, preliminary dielectric data are experimentally collected by using a standard open-ended coaxial probe. Then, the above complex dispersive data are exploited to optimize the antenna dimensions. Return loss measurements on water-glucose solutions with different concentrations are reported to prove the strong enhancement in the prediction of the resonant shift due to the variation of glucose level, when properly considering the loss tangent variation. Preliminary simulation results on blood are also reported.

CONVENED SESSION PAPERS Dielectric properties of biological tissues are important parameters that determine the energy deposition when tissues are exposed to electromagnetic radiation. Energy absorption is expressed as Specific Absorption Rate (SAR). In order to accurately calculate SAR it is important to know the complex and frequency dependent dielectric permittivity of the target tissue. In order to verify existing dielectric properties of data that was mostly obtained with the coaxial probe technique, in this paper we propose a different technique for dielectric properties extraction of biological tissues. The technique is based on transmission parameters measurement of a tissue sample placed in a rectangular waveguide. In the present work porcine and human samples are examined. Extracted complex dielectric permittivity parameters are compared with existing literature data and relatively big discrepancies are observed.

CONVENED SESSION PAPERS At microwave and mm-wave frequencies, the interactions of the human tissue with electromagnetic fields depend on the dielectric properties of the tissue itself. The knowledge of these properties of healthy and malignant tissues, beyond to be crucial in several biomedical applications, is necessary to fix the safety thresholds in policy-making and the exposure limits for the human body. In particular, breast tissues are of particular interest due to the relatively large diffusion of breast cancer. In literature, experimental data are available up to 20 GHz, consequently at mm-wave frequencies they are only derived from extrapolations. This paper presents a feasibility study based on the experimental results of a dielectric characterization of breast tissues. Two main aspects are addressed. First, the contrast achievable between normal and tumorous tissues, a key parameter for several biomedical applications. Second, the compliance of a mm-wave imaging system for breast cancer detection with the ICNIRP recommendations.

CONVENED SESSION PAPERS We have reconstructed microwave tomographic images of the Supelec breast phantom using our imaging fixture in combination with a multi-channel vector network analyzer. During this study we were able to recover images without the support of a priori information over a broad frequency range - 1100-1900 MHz. We then fitted the spectral values at each pixel within the field of view to a Cole-Cole curve and extracted the coefficients at each location. While the individual images at each frequency provided reasonably representations of the target permittivity and conductivity distributions, the fibroglandular features were generally quite blurred with the surrounding adipose region. However, several of the Cole-Cole coefficient plots provided a higher level of resolution for the inclusions. While there was a noticeably high level of artifacts outside of the breast phantom perimeter, the internal structures are quite representative of the target.

REGULAR SESSION PAPERS The augmenting need for remote monitoring and treating patients by biophysical sensors interconnected via Body Area Networks (BAN) has recently called researchers' attention. The private and confidential transferred data in such application require high information security. One of the solutions is to use human body as a transmission channel. The body surface-confined transmission restricts the off-body detection, increasing the system security. Also, it reduces the interference between BAN users. For better understanding the body channel propagation mechanism, a lossy multilayered human body model, made of skin, fat, muscle tissues, is established for numeric analysis in this paper, using complex frequency dependent dielectric property for each tissue. Transverse Resonance Method is applied to calculate dispersion and attenuation in the propagation direction up to 60GHz. Since the tissue thickness varies with different localization and different person, 3 skin thicknesses, typically 0.5 mm, 1 mm, and 1.5 mm, are considered and compared.

CONVENED SESSION PAPERS The 60 GHz band is being considered for many high-bandwidth wireless applications. To support standards development for these applications, NIST has developed an untethered 60 GHz, 8×16 MIMO channel sounder. It employs a pseudorandom bit sequence with a bandwidth of 4 GHz. The sounder can precisely measure radio propagation channel characteristics such as path loss, small-scale fading, delay dispersion, absolute delay, angle-of-arrival (AoA), angle-of-departure (AoD), and Doppler power spectrum. Its ability to measure the time dynamics of the millimeter-wave radio channel, when untethered and in motion, is unique. It employs electronically-switched MIMO antenna arrays, a robot for moving measurements and an automated one-dimensional positioner for precision measurements at fixed locations. Sounder performance is improved by use of pre-distortion filters and precision calibration of the RF and timing systems. Data showing initial AoD and AoA estimation error are presented along with initial test results for ground-plane reflection.

CONVENED SESSION PAPERS This paper presents a measurement-based analysis of both the specular- and dense multipath components (SMC and DMC) at 94 GHz in an indoor environment. A total of 15 positions were measured with a virtual antenna array system, from which we have calculated Power Delay Profiles (PDP). A method was developed that allowed for the full-polarimetric estimation of the specular propagation paths, after which the remainder was regarded as the diffuse spectrum. The behavior of the reverberation time, known from the theory of room electromagnetics, was analyzed based on this diffuse spectrum.

CONVENED SESSION PAPERS Recently, the fifth-generation mobile communication system (5G) has been widely investigated to accommodate increasing mobile users' traffic. In the 5G system, although the utilization of the higher frequency band above the 6 GHz band is expected, the detailed investigation for the applicability to the mobile communication is still necessary because of different radio channel characteristics compared with microwave bands. In this paper, 11 GHz band MIMO channel measurements were conducted in a street micro-cell environment. The result shows that the delay and the angular spreads of the specular paths were smaller compared with the results in the microwave band. The scattered signal component was weak compared with measurement results of indoor environments. The result is expected to utilize for the MIMO channel modeling in the higher frequency band.

CONVENED SESSION PAPERS This paper compares performance of the single-frequency floating-intercept model, the single-frequency close-in model, the multi-frequency alpha-beta-gamma model, and the multi-frequency close-in frequency-dependent model at 30 GHz, 140 GHz, and 300 GHz. For comparison purposes, extensive propagation measurements at 30 GHz (26.5--40 GHz), D-band (110--170 GHz), and 300 GHz (300--316 GHz) are conducted in the indoor line-of-sight (LoS) environments. The results show that if no measurement error is present in the channel impulse response, all four models have very similar performance and the model with the smallest number of parameters would be the optimal choice. On the other hand, the results show that in the presence of measurement errors or lack of detailed antenna gain characterization, models without physical anchor outperform models with physical anchor and correctly predict the reason for path loss mismatch between model and theoretical values.

CONVENED SESSION PAPERS In the present paper we analyse small-scale fading of reflections at 60 GHz using different antennas and bandwidths. The aim is to investigate the deterministic property of the channel in view of modelling and deployment of systems with larger bandwidths and higher directivity. We have investigated the scattering effect of a reflection on a wall emulating a beam-former in a NLOS condition. The results show that the distribution of the amplitudes fit better with a Rician than a Rayleigh distribution. Furthermore, we show that an increasing bandwidth and directivity increases the K-factor, supporting the idea of deterministic paths apart from the LOS.

CONVENED SESSION PAPERS This paper presents the comparison of power angular spectra at frequencies below and above 6 GHz, i.e., 2, 15, 28, 60 GHz. With the increased focus on millimeter wave frequencies for ultra-high data rates, a detailed understanding of channel frequency dependence has become crucial. The analysis in this paper is based on multi-frequency radio channel measurements in an indoor coffee room environment for both line-of-sight (LOS) and non-LOS scenarios. For multipath extraction, two different methodologies are used at below and above 6 GHz frequency bands, respectively. The results indicate that LOS channels demonstrate a similar spatial spread at all the frequencies considered, and hence can be spatially modeled in a similar fashion. The NLOS channels exhibit larger spatial spread overall. The paths at above 6 GHz channels appear to be spatially more consistent compared to those that are below 6 GHz, where penetrated and the diffracted paths also exist.

Different classes of passive and active NFRP ESAs that have successfully produced these effects will be reviewed, and several recently reported ESA systems will be introduced and discussed.

Results show good performance in terms of wide bandwidth and source independence.

REGULAR SESSION PAPERS We present a methodology to design cavity-excited omega-bianisotropic metasurface (O-BMS) antennas capable of producing arbitrary radiation patterns, prescribed by antenna array theory. The method relies on previous work, in which we proved that utilizing the three O-BMS degrees of freedom, namely, electric and magnetic polarizabilities, and magnetoelectric coupling, any field transformation that obeys local power conservation can be implemented via passive lossless components. When the O-BMS acts as the top cover of a metallic cavity excited by a point source, this property allows optimization of the metasurface modal reflection coefficients to establish any desirable power profile on the aperture. Matching in this way the excitation profile to the target power profile corresponding to the desirable aperture fields allows emulation of arbitrary discrete antenna array radiation patterns. The resultant low-profile probed-fed cavity-excited O-BMS antennas offer a new means for meticulous pattern control, without requiring complex, expensive, and often lossy, feed networks.

CONVENED SESSION PAPERS This study proposes a simple method for creating flat beam patterns in a near-field. In radio-wave transmission, the near-field beam efficiency of the beam-type wireless power transfer (WPT) system theoretically reaches 100%, but the beam pattern is not flat in the near field. In real beam-type WPT systems, the total beam efficiency (DC-RF-transmission, beam efficiency, and RF-DC conversion) can be improved by increasing the RF-DC efficiency of the rectenna. However, the rectenna requires a flat beam pattern in the near-field. In the present study, we create a flat beam pattern in the near field of a multicopter assisted wireless batteryless sensing system.

REGULAR SESSION PAPERS There is still discussion between which methodology to follow in measuring MIMO antennas for the LTE communication standard. There are two main ways of carrying out said measurements: statistically isotropic measurements (reverberating chambers) and anisotropic measurements (anechoic chambers). This work compares both methods implementing the SCME channel models for the anisotropic measurements and performing both azimuth rotations and full spherical rotations of the antennas using three Figures of Merit: ECC, MEG, and BPR. Here we show how isotropic measurements differ greatly from anisotropic measurements and how the performance of the antenna is dependent on the orientation of the device, rendering isotropic measurements not reliable enough.

REGULAR SESSION PAPERS The 4G standard is constantly evolving with more features being added to the standard specifications. Carrier aggregation and higher order MIMO are examples of features used to support higher data rates. The addition of features puts new requirements on wireless devices and this increasing complexity implies that Over-the-Air testing is more important than ever. At the same time it is important to keep the complexity of test setups to a minimum and to reduce measurement time, given the constant addition of new test cases. This paper elaborates on the RC as a fast, accurate and comprehensive Over-the-Air testing environment for assessing advanced features of state-of-the-art wireless devices. It is shown that a number of different testing scenarios can be realized with one test chamber using time efficient measurement algorithms. This test chamber can also be used for legacy standards and for assessing traditional metrics for antenna and wireless device performance.

REGULAR SESSION PAPERS MIMO Over the Air (OTA) measurements in controlled environments has been investigated both in academia and industry standardization groups. A several year effort to define MIMO OTA test methodologies, adequate channel models, channel model validation methods, etc. resulted in a Multi Probe Anechoic Chamber (MPAC) to serve as a reference for MIMO OTA performance certification for 2x2 downlink only. While efforts were made to converge MIMO OTA measurements with simulations, the closest results were achieved when adopting the concept of Absolute Data Throughput Framework (ADTF), where conducted and radiated measurements are used to validate the proper emulation of spatial channel model in controlled environments. This paper introduces an alternative method to assess link performance by combining electromagnetic and system simulations to address the concepts defined in the MIMO OTA standardization groups.

REGULAR SESSION PAPERS We present two configurations of multiport antennas for Multiple-input Multiple-output (MIMO) application. The configurations are comprised of three and four dual-polarized selfgrounded bowtie antenna as the element, respectively. The MIMO performance of both antennas is evaluated in Random Line-of-Sight (Random-LOS) and Rich Isotropic Multipath (RIMP) channel models as two edge propagation environments. Both configurations provide 360 azimuth and 120 elevation angular coverage in Random-LOS and full sphere coverage in RIMP. Using digital threshold receiver model and Zero-Forcing receiver, the performances of both configurations are evaluated in terms of Probility of Detection (PoD) and MIMO multiplexing efficiency calculated at 95% PoD level. The simulated results show a good performance for both structures in two edge environments, which can be concluded as a good performance in a real life situation.

REGULAR SESSION PAPERS A reconfigurable over-the-air chamber represents a reverberation chamber whose walls are lined with antennas that are terminated in reconfigurable impedances, allowing synthesis of a wide range of channel conditions for over-the-air testing of mobile wireless devices. While these chambers have potential for practical device testing, finding the right impedances to achieve the desired channel characteristics remains a challenging problem. This work explores the use of a simple gradient ascent optimization algorithm to determine the impedance states that achieve a specified spatial structure in the multipath, as characterized by the multipath power angular spectrum. The results highlight that the optimization is effective for synthesizing a desired power angular spectrum with a directive peak and a relatively low sidelobe level.

REGULAR SESSION PAPERS This paper shows the variation of clusters with the increasing number of antennas. The data was collected from the massive MIMO mobile measurement at 3.5 GHz, in line of sight (LoS) and non line of sight (NLoS) conditions, respectively. And the virtual measurement method is used to form the 64-element, 128-element and 256-element virtual antenna array from the 32-element antenna array. After estimating parameters by the space-alternating generalized expectation maximization (SAGE) algorithm and clustering by KPowerMeans algorithm, the parameters of clusters are displayed in angular domain and delay domain. The cluster-level angular power spectrums (APS) are shown, the intra-cluster angular spread (AS) and intra-cluster delay spread (DS) of these 4 groups of data are calculated, to display the clusters' variation when antenna number increases.

REGULAR SESSION PAPERS In this paper, a scheme for coupling free-space THz radiation into a nonlinear whispering-gallery mode (WGM) resonator is presented. The purpose is to detect the weak THz radiation from the cosmic microwave background (CMB) by up-converting the signal into the optical domain via to the nonlinearity of the medium. Such high-sensitivity receiver has theoretically shown capabilities towards photon counting at room temperature, however, it is critical to efficiently couple the THz radiation into the resonator. Therefore, by using the Schelkunoff-Waterman method (the so called T-matrix method) we perform an analytical evaluation of two different free-space coupling techniques: a free-space Gaussian beam, and a Gaussian beam incident in a silicon lens under total internal reflection. By comparing the excited modes in the resonator, the optimal parameters for each case are given.

REGULAR SESSION PAPERS Corrugated horns are widely used in many applications, including radio astronomy, because of their high performance over large bandwidths. However, the always increasing demand for wider frequency coverage cannot be met by traditional conical corrugated horns with typical fabrication constraints at (sub-)mm wavelengths. The usual way to overcome this limitation is to use profiled corrugated horns, such as the 275-500 GHz horn presented in this paper. As an alternative, we propose and demonstrate that conical corrugated horns can achieve ultra-wideband (UWB) performance by changing the depth of corrugations along the horn. A design for the 67-116 GHz band is presented. Fabrication of these two designs is on-going and measurements will be presented at the conference.

REGULAR SESSION PAPERS A validation of a recently proposed equivalent circuit model for describing the radiation of photoconductive antennas is shown in this work. The validation is obtained by comparing the power estimated by the model against radiated power measurements of a manufactured prototype. The model describes the feeding mechanism of an antenna provided via a photoconductor gap, when it is optically pumped by a laser, taking into account for the electrical proprieties of the material, for the geometrical sizes of the gap, and for the laser power excitation. Two different measurement setup have been used, in order to verify the accuracy of the measurements. In order to compare the estimation of the power predicted by the model and the measurements, an evaluation of the efficiencies involved in the THz measurement quasi-optical system has been performed for both the setups. A good agreement is achieved between measurements and power estimated with the model.

REGULAR SESSION PAPERS This paper proposes a novel terahertz (THz) probe based on a pyramidal-shaped TE10 mode rectangular open ended waveguide (OEWG) integrated with a 45º-inclined linearly polarized (LP) element. The radiating element, deposited on top of the OEWG, is realized using standard printed-circuit and plated-through-hole technologies. The pyramidal fixture, situated beneath the substrate, is made of brass with gold plated. Experimental results show that the proposed probe can present an impedance bandwidth (VSWR ≤ 2) better than 15.2% from 279 to more than 325 GHz. Within the impedance bandwidth, the gain varies from 5.3 to 10.2 dBi and all radiation patterns are symmetric with low cross-polarization and back radiation levels. The proposed probe is a good candidate for Mueller imaging in THz range.

REGULAR SESSION PAPERS In this work, the tunable properties of nematic liquid crystals are exploited in order to design a Fabry-Perot cavity (FPC) leaky-wave antenna (LWA) with beam-steering capability at fixed frequency in the THz range. The considered design is a grounded dielectric slab covered with a multistack of alternating layers of low- and high-permittivity dielectric materials, consisting of nematic liquid crystals and alumina thin films, respectively. The former allows for achieving the beam-steering capability at a fixed frequency. Full-wave simulations confirmed the pattern reconfigurability of the device, thus opening very interesting possibilities for the realization of reconfigurable THz antennas.

REGULAR SESSION PAPERS We present in this paper a design of a high gain antenna for radar-based non-contact measurement systems in the k-band frequency. The proposed antenna consists of a slot on a multi-grooved metal structure (flange) and a frequency selective surface (FSS) acting as a flat lens. Often, grooved (or corrugated) surfaces and frequency selective surfaces are used to enhance antenna gain features. The combination of these two techniques could provide more gain with a small size antenna. In this sense, dimensions of both grooves and FSS are optimized to reach the maximum gain without increasing the size of the antenna. All simulations and optimizations are carried out using electromagnetic full-wave tools. Next, a prototype of the proposed antenna is manufactured and characterized. More than 15 dB of gain is obtained over the whole bandwidth with a peak gain of about 17.5 dB is measured around the frequency 24.5 GHz.

REGULAR SESSION PAPERS The design of circular dual and quad ridged horn antennas covering the 18 to 45 GHz band is discussed. An exponential taper and blending fillet for the ridge profile are presented to minimize 3 dB beamwidth variation while maintaining high boresight gain for both dual and quad ridge horns. Boresight gain for a quad ridge design is greater than 15 dBi, while boresight gain greater than 17.9 dBi is shown for a dual ridge circular horn design. Both horns have axial 3 dB beamwidth variation less than 5 degrees over the entire frequency band.

REGULAR SESSION PAPERS A wide field of view dual-lens system is presented in this contribution. The antenna is designed has to work from 250 to 500 GHz. An outline of the design considerations is discussed. The lens system is designed for near-field focusing, at a range of 2.1 m and can be refocused by displacing one lens in from 1.8 to 2.3 m. The simulated results show that over the required field of view of ±25.4° (±1 m at the nominal range) the gain variation is approximately 3 dB. Moreover, the half power beamwidth at the edge of the field of view increases by only a factor 1.4 compared to the broadside pattern. This makes the design suited for imaging systems since the image resolution is practically constant over the field of view. The dual lens system was fabricated and the measurements confirm the predicted performance.

REGULAR SESSION PAPERS In this paper, a single-fed four-panel 4x1 patch array antenna operating at 2.43 GHz with switched beam capability is proposed. The design allows the beam to be switched between four discrete directions giving 360° coverage. The antenna beam is switched over the azimuth plane for Φ = 0°, Φ = 90°, Φ = 180°, and Φ = 270°. The beam control is achieved by using GaN-based HEMT SPDT switches. Only three SPDT switches are integrated directly into the structure, allowing its nature to be electrically controlled over the desired four directions. Simulated and measured reflection coefficients and radiation patterns for the four cases are presented and discussed, showing good agreement. The antenna gain is around 3.8 dB including switches losses at 2.43 GHz.

REGULAR SESSION PAPERS In this paper, a technique to maximize the directivity of an antenna array is presented. It consists of a fed monopole and a loaded parasitic one. The nature and value of the load are obtained using the Uzkov equations that calculate the current weighting coefficients in the case of two separately fed antennas to maximize the gain and the directivity in one direction. Reconfigurability is achieved by using reflectors and directors activated by pin diodes to reduce the back radiation and pointing in the desired direction. Thus a system of two elements, one fed and the other loaded with an inductor, having a maximum gain of 5.2 dBi at 2.45GHz in azimuthal directions 90° and 270° is obtained. The system is compared with a system of two antennas fed separately.

REGULAR SESSION PAPERS Retrodirective antennas used for radiative wireless power transfer (WPT) are typically resonant and exhibit strong backscatter, a limited field of view and small bandwidth. These limitations are here overcome by using an array of long slots fed by parallel plate waveguides (PPWs). It is shown that the array can collect the total power impinging from a remote source over a large field of view and bandwidth. The conclusions arrived at for the infinite case are extended to the finite case through full-wave simulations.

REGULAR SESSION PAPERS In this paper, a retrodirective antenna (RDA) array for wireless power transmission (WPT) is presented. Applications include the charging of mobile device batteries wirelessly. Thanks to the principle of phase conjugation in mixers, retrodirectivity can be achieved in the far-field. More specifically, the reported RDA architecture deals with an active transmitter module to retrodirect a received beacon tone, with increased power, from a mobile unit and with circularly polarized (CP) radiation. Measurements and simulations show a good agreement in terms of the retrodirective tracking capabilities. In addition, a new RDA architecture is also proposed for WPT, using sub-arrays, in order to boost the overall received power at the mobile while also not significantly increasing the costs of the active transmitter module. Other applications for the proposed RDA circuit element include target tracking, low-cost sensor charging, and other WPT systems.

REGULAR SESSION PAPERS The monostatic radar cross section (RCS) is an important design parameter for many applications, but accurate RCS prediction of an electrically large structure continues to be a challenging task. High accuracy demands and a complicated geometry often mean that asymptotic methods are not applicable, while a full-wave method has traditionally required very large computational resources. In the present paper, we avoid the $f^6$ computational time scaling of the Method of Moments by applying the Multi-Level Fast Multipole Method (MLFMM). A range of modifications to the traditional way of applying MLFMM to monostatic RCS are implemented in order to achieve strong computational performance even on modest hardware.

REGULAR SESSION PAPERS Approximate numerical modeling of microwave bistatic scattering (BS) from anisotropic rough surfaces, simulating large baselines radar bistatic system, is analyzed in this contribution. The investigation is performed in the framework of the SAOCOM-CS scientific satellite mission, a small satellite under design by the European Space Agency, to be associated with the Argentinian SAOCOM 1B satellite, aiming at collecting bistatic radar data at L-band. Similar bistatic concepts are being investigated at C-band as well. The main features of the normalized radar cross section (NRCS) of the sea surface in different operating conditions are discussed. This represents the first step to assess the potentiality of bistatic radar observations of natural surfaces with large baseline, and to gather valuable information on the bistatic scattering properties for the design of future spatial missions.

REGULAR SESSION PAPERS Wind turbine clutter has gradually become a concern for the radar community for its increasing size and quantity worldwide. Based on the S-band polarimetric Doppler PARSAX radar measurements, this paper demonstrates the micro-Doppler features and spectral-polarimetric characteristic of wind turbine clutter, the probability distribution functions of different spectral-polarimetric variables. Finally, a simple thresholding method to remove wind turbine clutter is put forward, and its effectiveness can be verified by the measured data. This work is expected to contribute to developing effective algorithms for this dynamic clutter suppression for operational weather radar.

REGULAR SESSION PAPERS Wave propagation over terrain topologies and surface wave propagation relate to several practical applications the simulations of which often become very complex and reach their limits due to the size of objects. Exemplarily, one application is the illumination issue of wind turbines located on different terrains, such as hills in the context of potential bearing errors of the VHF omnidirectional radio range (VOR) due to multipath propagation. Preferably, due to the flexibility of measurements, such investigations are conducted in scaled environments where the object's dimensions are decreased by the same factor the frequencies are increased. This contribution presents the manufacturing process of lightweight, modular pieces with carbon twill fabric on a rigid foam, fastened by epoxy resin using the example of terrain modeling. Corresponding material parameter characterization with radar cross section measurements is carried out. A generic scaled mountain model is constructed and measurements of over-the-hill-propagation are conducted and interpreted Björn Neubauer 833947 Technische Universität Braunschweig Germany 1 Robert Geise 318057 Technische Universität Braunschweig Germany 0 Georg Zimmer 864125 Technische Universität Braunschweig Germany 0 Oliver Kerfin 1447343 Technische Universität Braunschweig Germany 0 Angela Andree 1446062 Technische Universität Braunschweig Germany 0 Norbert Ueffing 1446065 Piller Germany GmbH & Co.

REGULAR SESSION PAPERS The analysis of the Doppler signal returned by rotating targets is of great interest in the framework of target recognition and equipment monitoring. An analytical expression of such a signal already exists for the far-field case, based on the Jacobi-Anger expansion. An extension of this analytical expression is proposed for the near-field case. The solution involves a closed-form expression of each harmonic complex coefficient. An error analysis is carried out.

REGULAR SESSION PAPERS In this work, the impact of different system configurations on the SNR performance of hybrid-passive-active phased arrays is studied. The separation of the functional core components of active arrays into active and passive parts provides the possibility to reduce power consumption, size and cost, which is of interest especially in mobile applications. Power consuming and expensive active components, such as LNAs, can be shared by multiple antenna elements, whereas passive components, e.g. passive phase shifters, are assigned to each antenna element for beam steering. To estimate the performance of such systems, a noise model is derived for a planar M times N, corporate fed array in tile construction. With this model, it is possible to determine an optimum array configuration in terms of array size and LNA distribution for a given SNR design goal and a given set of limiting factors.

REGULAR SESSION PAPERS A dual-band dual-polarized compact antenna array is designed for intended use in robust global navigation satellite receivers. The four-element antenna array is connected to an eigenmode-based decoupling and matching network to compensate for the radiation efficiency degraded by mutual coupling. The resulting eigenmodes of the array are then fed to an RF-IF front-end for down-converting, filtering, and power amplification. Finally, the signals are carried to a digital receiver for decoding and tracking. Field measurements proved the usability of certain left-hand circular polarized modes for receiving the navigation signals, particularly at low elevations. This possibility enhances the receiver robustness against polarization distortion caused by multipath, and thus improves the tracking accuracy. Measurements help also to decide which left-hand modes should be selected for a practical dual-polarized receiver if the number of channels available for array signal processing is limited.

REGULAR SESSION PAPERS In this work the problem of synthesizing the excitations of a linear array, clustered into contiguous sub- arrays of irregular length, is addressed. By suitably exploiting the behavior of clustered array aperture distributions (i.e., step-wise discrete functions), the problem has been formulated as the minimization of the total variation (TV) of the excitations, satisfying a matching condition on a predefined reference pattern. In virtue of the sparse nature of the unknowns, the minimization problem has been solved by means of an efficient total variation compressive sensing (TV- CS) optimization approach. A simple example validating the proposed technique is finally reported.

REGULAR SESSION PAPERS Pattern recovering of conformal phased array on changing surfaces is receiving an increasing attention in the last years. This paper presents the pattern recovery of a strongly deformed conformal phased-array using the projection method. A 4 × 4 flat array is placed on a doubly curved surface. The phase compensation technique is applied first on rows, and then, considering rows as single antenna elements, on array columns. This technique was proved to be effective in recovering direction and width at half maximum of the pattern main lobe and in suppressing side lobes. Analytically predicted recovered patterns are confirmed through full-wave numerical simulations.

INVITED SESSION PAPERS Conventional antenna gain measurement techniques involve transmission measurements of additional antennas in addition to antenna under test. This not only increases the amount of measurements but also introduce error associated with setup changes and reference gain accuracy. The scattering and unbalanced current radiation from the cable can sometimes introduce measurement error. Furthermore, the cable loss associated with the long cable below VHF and above Ku band becomes a major limitation factor in measurement sensitivity. This talk discusses an alternative antenna gain measurement technique based on backscattering measurement of the antenna. This approach completely eliminates the cable connected to the antenna and reference gain antenna. The methodology and simulation examples will be demonstrated. The accuracy and limitations of this method will also be discussed. This gain measurement could be very useful for determining gain patterns of antenna in situ such as antenna on chip, wearable antennas, and antenna on wafer.

INVITED SESSION PAPERS The promise of 5G and internet of things (IoT) is a future in which an inconceivable number of everyday devices are connected with incredible speeds. 4G was the first mobile system actually designed with global standardization. This was one of the key factors in the success of 4G and the speed of its deployment. Today, the main objective of the communication community is to realise common standards for 5G and build a global system. The deployment of test systems at various prestigious events will then follow. The 2018 Winter Olympics in Korea and the 2020 Summer Olympics in Japan are examples of such pilot systems. Finally, users will have 5G devices and will enjoy the full performance of this new technology. We know that test and measurements of 5G enabled devices and base-stations will differ widely from what we are doing today. 5G implies higher and widely available spectrum at frequencies up to 100GHz, which can accommodate the implementation of Massive-MIMO involving multiple small antennas and in-device processing. This will move the emphasis from the antenna towards system testing. Important parameters, determined from conducted testing for 4G, will likely be performed in Over-The-Air (OTA) setups in tomorrow's 5G. This puts a strong requirement on the measurement industry to provide effective testing solutions to developers, industries and regulators. As testing technology, the very effective multi-probe systems have evolved with the development of 1 to 4G technology in the last 25 years. It is today a reference for OTA testing of such devices. While concepts such as testing in near and far field (NF, FF) is less critical in current 1-4G standardisation, NF testing and NF performance of devices is likely to be a critical issue for 5G. In this paper/presentation we will give an introduction to existing measurement technology and a vision on the evolution of testing technology for 5G enabled devices.

Firstly, antenna design techniques for on-body to on-body communications are discussed; (1) TM21 higher order mode patch antenna with monopole-like radiation; (2) additional corrugation/EBG structure for body surface wave enhancement. Secondly, designs of dual-modes antennas for repeater systems are introduced. In order to design dual-modes antennas for in-on-on and on-on-off communication links, we propose a few miniaturization techiques as well as how to integrate two radiating elements with different operating frequencies into a single antenna structure. Lastly, the textile antenna using all-textile materials such as conductive textile, conductive thread, and non-conductive fabric for practical wearable applications is presented.

INVITED SESSION PAPERS Under far-field conditions, the transmission of electromagnetic waves is commonly described by the Friis transmission equation. Wave propagation effects can be included by ray concepts together with appropriate phase terms. Motivated by the needs of near-field antenna measurements, we will look into a couple of near-field antenna transmission equations, where we will find that spectral formulations of such transmission equations are commonly advantageous in terms of physical insight and numerical treatment. A very flexible and numerically advantageous near-field transmission equation works with spectral propagating plane wave representations and it is found that this equation is nothing else than a near-field generalization of the Friis transmission equation. Based on this transmission equation, we will formulate antenna field transformation algorithms and we will show the performance of such algorithms for field transformations in complex environments, where reflection and scattering effects are involved or where only near-field measurements without phase information are available.

The instrument shall probe the inner structures of the icy crust of the moons Callisto Europa and Ganymede up to a depth of 9 km. For ensuring a sufficient penetration depth the instrument is operated at the frequency range 7.5 - 10.5 MHz. The instrument is equipped with a lambda/2 dipole with decentral feeding. Its RF characteristics are strongly affected by the electromagnetic coupling to the S/C surfaces and also the RF verification is strongly constrained by any coupling to the environment. The presentation outlines the envisaged test approach for verifying impedance, efficiency and selected directions of the antenna pattern first for the isolated antenna and thereafter for an antenna mounted on a S/C mockup.

CONVENED SESSION PAPERS Measurement of the radiation properties of low gain antennas at VHF frequency is in many cases a challenging task. Measurements performed in shielded anechoic chambers are usually preferred to outdoor ranges because they are not subject to the electromagnetic pollution and less affected by the scattering of the environment. However, different source of errors, such as truncation of the scanning surface and the presence of echoes caused by a poor reflectivity of the anechoic chamber, could affect the measurement results. In such cases, advanced post-processing techniques must be involved. In this paper, the results of two Engineering Models of a low gain VHF space antenna are reported. The first one has been tested in a multi-probe automotive hemispherical range and applying an advanced processing, in order to mitigate the truncation errors. The second has been measured in a spherical multi-probe system with smaller truncated area applying the standard data processing.

A periodic structure is glide-symmetric when its lattice is created by a periodic mirroring and translation. These structures were of the interest to the microwave and antenna community during the '60s for one-dimensional periodicities. Recently, research on metasurfaces has revived the study of glide-symmetric structures due to their exceptional qualities in terms of low dispersion and rejected bands.

CONVENED SESSION PAPERS In this paper, the analysis method for analyzing metasurface parallel-plate waveguides with glide symmetry is presented. The analysis method is based on Floquet-mode representation of the EM field inside the parallel-plate, and on matching it with the EM field at the waveguide opening. By this, a characteristic equation for the propagation constant of the waveguide mode is derived. The analysis method is tested by comparing the calculated propagation constant with the results obtained by a general electromagnetic solver.

CONVENED SESSION PAPERS A metasurface which has glide symmetry in two orthogonal directions is given here as the building block for the design of surface wave lenses. This metasurface is shown to have reduced frequency dispersion when compared to a similar structure with reflection symmetry only. This work has the potential to create graded index lenses, with a high mode-index contrast, for use in surface wave antenna applications.

CONVENED SESSION PAPERS The use of gap waveguide technology is increasing continuously. In this work we present the first studies on the use of a new type of periodic structure to create the desired stop band and its application to design array antennas. The new unit cell belongs to the known as glide-symmetric structures and has a very simplified manufacturing. The latter is due to the larger periodicity of the structure when compared to the classical pins but also because manufacturing holes is always easier than making pins.

CONVENED SESSION PAPERS This paper presents an all-metal parallel plate waveguide (PPW) Luneburg lens designed using an array of subwavelength Fakir bed of nails unit-cells. Variation of the metal post height and PPW-spacing modulates the effective refractive index. The lens operates in the Ku-band of frequencies, with more than 40\% bandwidth, in a quasi-TEM mode. Broadband and low loss, with high directivity and wide field-of-view, this antenna could be an excellent candidate as a lens-like beamformer for multiple beams satellite communication applications.

CONVENED SESSION PAPERS In the last decades, the advances in the micro and nano-fabrication techniques have led to the development of microdevices that have improved the possibility of analysis at cell level. These devices can be used in different applications: cell detection and identification, manipulation, cell treatments, but in particular they seem extremely promising for nanosecond pulses applications, where the requisite of broadband matching becomes highly demanding. In this paper after a brief review of applicators for nanosecond pulses, a multi step procedure for a good design of microdevices is fixed and an example of microchamber design is given.

CONVENED SESSION PAPERS Electric pulses can modify properties of cells membrane and make it permeable to molecules that normally are non-permeant. One way to study this effect is therefore to observe transport of molecules across the membrane. However, the outcome of such experiments not only depends on damages induced to the membrane but also on properties of the transported molecules which are investigated and on the transport mechanisms which are involved. Some other approaches, are however available and can provide more straight forward information on the state of a membrane. Electrical diagnostics, such as bioimpedance or patch-clamp, can provide direct information on the modification of the conductance of the cells membrane. Additionally, some optical diagnostics such as measurement of transmembrane voltage using voltage sensitive dyes can also be used to study modification of membrane conductance induced by pulsed electric fields. The benefits and drawbacks of each approaches will be discussed.

CONVENED SESSION PAPERS Irreversible electroporation (IRE) is a technique to kill cells by delivering a series of short-duration, high voltage square wave electric pulses into tissue to alter the native cellular transmembrane potential, creating irrecoverable nanoscale defects in the cell membrane. IRE protocols constrain Joule heating below temperatures that cause coagulation of extracellular proteins, and consequently spare critical structures that contraindicate other thermal-based therapies. Tissue-level characterization and optimization of IRE treatment conventionally requires costly and logistically complex in vivo experiments, since affected zones cannot be visualized in expired ex vivo tissue. This has limited IRE protocol evolution. Here, an alternate method using active perfusion of freshly harvested organs with an appropriate viability stain is described, and offers an approach to visualize IRE-affected tissue. The lesions were validated against protocol-matched in vivo trials. This offers an approach to cheaply expedite IRE development, permitting faster protocol and device optimization, ultimately offering better clinical outcomes.

REGULAR SESSION PAPERS Recent papers showed that when dealing with nanosecond pulsed electric fields (nsPEFs), bipolar pulses proved far less effective at membrane permeabilization and at cell killing than monopolar ones, contrary to what happens in the microsecond range. The mechanism at the basis of such selective response of cells is not fully elucidated. One hypothesis worthwhile to test could be a direct action of nsPEFs on intracellular enzyme reactions. The goal of this study is to investigate possible enzyme response due to the application of nsPEF monopolar and bipolar of intensity of 108 V/m and duration of 100 ns on the superoxide dismutase (SOD,Cu-Zn) enzyme, by means of a molecular dynamics (MD) modelling approach.

CONVENED SESSION PAPERS Airspaces worldwide are becoming more heavily used. This includes the use of unmanned aircraft systems, which is rapidly growing. In order to ensure reliable communication for aircraft, the air-ground channel must be accurately characterized. A significant channel impairment that has not been thoroughly studied is airframe shadowing—obstruction of the line-of-sight signal by the aircraft itself. In this paper, we report on measured results for this shadowing phenomenon in two frequency bands, for a medium-sized aircraft. We present results for two example shadowing events in terms of shadowing depth and duration, and provide distributions of shadowing depth and duration. We show that for both bands, airframe shadowing can be more than 30 dB, and can last for tens of seconds.

CONVENED SESSION PAPERS The paper proposes a geometrical-statistical modeling approach for the air-ground channel for \ac{CNS} systems in the L-band frequency range. We sketch the architecture of the model with its six elements and show how their parameters can be derived from measurement data. Preliminary results obtained from a relatively small set of measurement data reveal that the proposed modeling approach is well suited to capture the time variant behavior of the channel. However, a considerably more extensive evaluation of the measurement data will be necessary to finalize the parameter settings of the proposed channel model.

CONVENED SESSION PAPERS A new model addressing scattering from tree canopies is presented in this paper. The model is based on a combination of physical optics and the multiple scattering theory (MST) and provides significant improvements when compared to the case when only MST is utilized, especially the correct near field calculations. The model is validated against MST at 2 GHz and 10 GHz for the case of an artificial scenario and also against a set of experimental data obtained at 2 GHz for a single isolated tree.

CONVENED SESSION PAPERS The Unmanned Aerial Vehicle (UAV) is going to play an important role in fifth generation communication systems for establishing seamless coverage in various scenarios due to its low- cost and flexibility. Understanding the UAV wireless channels is the basis for its application. In this paper, a recently conducted measurement campaign for the UAV wireless propagation channel in a suburban scenario in Madrid is introduced. Based on the Universal Software-defined Radio Peripheral (USRP) equipment, narrowband measurements at frequency of 5.76 GHz and broad- band measurements at frequency of 1.817 GHz are performed. The path loss, K-factor, power delay profiles (PDPs), multipath components (MPCs) and root-mean-square (RMS) delay spreads (DSs) are presented. Xuesong Cai 1328687 Tongji Unversity P.R.

CONVENED SESSION PAPERS Radio wave propagation from a satellite based emitter to an airborne located receiver is of interest for applications like passenger internet access during a flight, air traffic management or positioning by global navigation satellite systems (GNSSs). Especially for the last two applications that are related to safety-of-life functionality, accurate channel models for software based system testing are essential. Current state-of-the art channel models for the satellite-to-aircraft case lack of accuracy in terms of modeling all propagation impairments. In this contribution, we describe an airborne experiment using Global Positioning System (GPS) satellite emitted signals to characterize the wave propagation channel from a satellite to an airborne platform. First results on ground reflected multipath are provided.

CONVENED SESSION PAPERS In the field of antenna diagnosis and characterization, the Sources Reconstruction Method (SRM) has been proved to be a powerful tool enabling the use of arbitrary-geometry measurement and reconstruction surfaces. The SRM has been extended for phaseless antenna characterization using two or more acquisition surfaces, as a simpler (but slower) alternative to holographic techniques. One of the main drawbacks of phase retrieval using multiple surfaces is the need of solving a set of nonlinear equations relating the measured amplitude with a set of equivalent currents using iterative, time-consuming methods. This contribution aims to improve the applicability of this methodology by reducing the time cost of the iterative procedure by means of Graphics Processing Units (GPU). Speed-up rates ranging from 50 to 90 times compared with sequential CPU (Central Processing Unit)-only implementation have been achieved.

CONVENED SESSION PAPERS For a little over a decade, a measurement and post-processing technique named Mathematical Absorber Reflection Suppression (MARS) has been used successfully to identify and then suppress range multi-path effects in spherical, cylindrical & planar near-field antenna measurement systems and far-field and compact antenna test ranges (CATR). Much of this early work concentrated on verification by empirical testing however some corroboration was obtained with the use of computational electromagnetic simulations. The recent development of a highly accurate computational electromagnetic simulation tool that permits the simulation of "measured" far-field pattern data as obtained from using CATR has for the first time permitted the careful verification of the far-field MARS technique for a given AUT and CATR combination. For the first time, this paper presents simulated "measured" far-field pattern data in the presence of a large scatterer and then verifies the successful extraction of the scattering artefacts using standard FF-MARS processing.

CONVENED SESSION PAPERS In measurement scenarios with ground planes the boundary condition has to be included appropriately in the near-field to far-field transformation. For spherical near-field antenna measurements, techniques exist to include a ground plane in the xy-plane z = 0 m. In this paper we will describe a transformation procedure including a translation of the transformation origin, so that the ground plane can be at any height z to overcome that limitation of existing techniques. The procedure is demonstrated by a simulation and measurement example.

CONVENED SESSION PAPERS The upcoming migration of satellite services to higher bands, namely the Ka- and Q-bands offers many advantages in terms of bandwidth, data rates and system capacity. However, it poses challenges as propagation effects introduced by the various atmospheric phenomena are particularly pronounced in these bands and can become a serious constraint in terms of system reliability and performance. This paper outlines the goals, organization and some first results of an ongoing large propagation campaign consortium formed across Europe under the supervision of the European Space Agency; the campaign, shall ultimately assist in the validation and development of channel models targeting these-bands. Finally, the consideration of diverse climatic conditions and elevation angles along with the evaluation of the frequency and spatio-temporal effects, shall support the development of Fading and Mitigation Techniques and their assessment using real data.

In order to study propagation effects for future satellite communication frequencies both in temperate and tropical climates, JOANNEUM RESEARCH carries out two long-term propagation measurement campaigns, one in Europe with the Alphasat Aldo Paraboni payload at Ka-band (19.7 GHz) and Q-band (39.4 GHz), and another one in two sites in the tropical region of peninsular Malaysia, where the climatic differences affect the propagation channel characteristics. This paper reports on both campaigns and presents the statistical analysis of experimental results and their comparison with the existing ITU-R propagation models.

This paper presents results of two year measurements at 20 GHz and co-sited meteorological data. The results suggest that with 7-8 dB margin, services can be provided with 99 % availability for systems with elevation angles as low as 3.2 deg. Measured attenuation distributions support International Telecommunication Union prediction methods within 3 to 4 dB for 99.99 % of the time. However, scintillation and multipath are not well predicted at the lowest elevation angle.

CONVENED SESSION PAPERS This paper reports on the development and experimental characterization of a high data-rate communication link at 240GHz with highly-integrated direct-conversion quadrature transmitter and receiver modules implemented in 130nm SiGe HBT technology with ft/fmax of 350/550 GHz. Both modules employ a low-cost chip-on-board packaging scheme with single-chip TX and RX front-end circuits accommodating wideband silicon lens-integrated wire ring on-chip antennas. The key highlights of the developed hardware are its high RF and IF operation bandwidths available from the printed-circuit board-level. With the preliminary wireless transmission tests, a 20Gbps and a 24Gbps transmission speed with an EVM of 24% was demonstrated for BPSK and QPSK modulation schemes at a distance of 90cm with no channel equalization applied. For a 10Gbps BPSK, an error-free communication link could be established.

CONVENED SESSION PAPERS Recently, there has been an increasing interest in the THz gap due to the attractive applications that can be developed. Among these applications, high data rates communication system links get an important relevance due to the potential high bandwidth that can be obtained. In this paper, a frequency tripler and a fourth harmonic mixer for a wireless communication link at 300 GHz has been designed. Conversion Loss (CL) of the tripler is around 15 dB for 65 GHz bandwidth in which the best value is 12 dB for 318 GHz. For the fourth harmonic mixer, the CL obtained is around 18 dB within 41 GHz bandwidth. The best value is 10.2 dB for 301 GHz. Jose M.

CONVENED SESSION PAPERS Graphene-based plasmonic nano-antennas are envisioned as the enabling component for communication in the Terahertz (THz) band (0.1-10THz). Despite their efficiency and due to their size, the total radiation power is expectedly very low. To overcome this limitation, plasmonic nano-antenna arrays are proposed. In this paper, by using analytical models backed by numerical simulations, the performance of such arrays are analyzed while taking into account mutual coupling effects. It is shown that a nano-array can provide significant gain in relation to only a single nano-antenna while still occupying a compact footprint. The results in this paper serve as a building block towards future THz communication systems.

CONVENED SESSION PAPERS THz impulse communications is a new system concept based on an imaging radar that we have been developing for biomedical imaging applications the past ten years. Its hybrid architecture combines the high-peak-power and spread-spectrum of photoconductive-switch transmitters with the high-responsivity and broad-bandwidth (RF and video) of Schottky-rectifier receivers.

REGULAR SESSION PAPERS The interest for making vehicular transportation safer and more efficient has increased exponentially in recent years. To develop such vehicular communication systems, accurate models for the propagation channel are needed. This work analyzes the channel properties of different wireless communication systems within a vehicular communication environment with deterministic modeling. Three different frequencies have been analyzed: 868MHz, 2.4GHz and 5.9GHz. An in-house 3D Ray Launching code has been used for that purpose, taking into account the movement of the vehicles, leading to time and space-frequency models. Results present the great influence of multipath propagation in these type of environments, leading to a great aid in the identification of the optimal location of the transceivers, in order to minimize power consumption and increase overall service performance.

REGULAR SESSION PAPERS This paper presents the time-variant channel characteristics at 20 GHz band for line of sight (LoS) scenario in urban street canyon environment. A measurement campaign was conducted using a channel sounder for 20 GHz band with a 50-MHz-bandwidth. A uniform planar array (UPA) in form of 16-by-16 matrix was also used for the receiver side in order to measure time-variant power delay profiles, azimuth/elevation angle of departures (AoD/EoD). The measured results show that the correlation values of standard deviation (std) of delay spreads (DS), azimuth spread of departure angles (ASD), elevation spread of departure angles (ESD) and transmission distances are 0.78, 0.22, 0.78, respectively. Moreover, the correlation value of std and average of DS is high about 0.98. One the other hand, the correlation value of std and average of ASD, and the correlation value of std and average of ESD are low about 0.04 and 0.55, respectively.

REGULAR SESSION PAPERS A null steering method for Forward-Looking Ground Penetrating Radar (FLGPR) is presented. The radar consists of two arrays (one at L-band and one at X-band) of wideband horns that form synthetic apertures at the vehicle advanced. The null steering method is applied to the SAR vertical view (intensity vs. range and height) image to compensate for the lack of vertical image resolution and help determine if a scatterer is above the ground or buried. First, a target point is selected in the original SAR image, then a null for point spread function (PSF) is calculated for that point. The null PSF is applied to field data to indicate the position of the scatterer. This method is tested with a full-wave scattered field synthetically generated by FDFD, and with field measurement data.

REGULAR SESSION PAPERS Frequency-diverse imaging is an all-electronic method, capable of sampling the scene to be imaged without the need for a mechanical scan or active circuit components. In order to optimize the imaging characteristics, such as imaging resolution and fidelity of the reconstructed images, the antennas used within this scheme need to be optimized. It is demonstrated that using a Mills-Cross iris distribution, superior sampling of the Fourier components (wide support extent and minimum sampling redundancy) can be achieved. Using the optimized antennas, an experimental imaging system is built, reconstructing a good quality image of a cross-shaped target in less than 0.1 seconds.

REGULAR SESSION PAPERS RCS analysis is the study of the scattering behavior of an object. The objective is to determine the main scatterers from measurements of the backscattered electric field. It is generally achieved by Radar Cross Section imaging. This leads to an ill-posed inverse problem because the system to solve is underdetermined. It is then necessary to regularize the problem by adding prior information. In this paper, a new constrained and sparse regularization method for Radar Cross Section imaging is proposed. It is based on the finite spatial electromagnetic extension of the target and its expected small number of scatterers. A least squares criterion with a L1 penalty and support constraints is developed. It is minimized by an efficient algorithm resting on an ADMM. The application to real scattered measurements is very promising, with a limited computation time. Compared to the conventional approach, the image resolution is drastically increased.

REGULAR SESSION PAPERS This paper proposed a volume pixel subspace based optimization method (SOM), to solve the electromagnetic imaging problem of the wave impenetrable objects/perfect electric conductor (PEC). In this proposed method, the PEC objects are approximated by highly lossy dielectric scatterers with pure imaginary permittivity and thus volume pixel SOM is successfully employed. There is no prior information such as the number and locations of scatterers required in the inversion. Synthetic data as well as experimental data are both employed to test the validity of the method. The surface pixel SOM is also used to compare with this volume pixel SOM, showing that the nonlinearity of volume pixel SOM is reduced greatly and is much faster than the surface pixel SOM.

REGULAR SESSION PAPERS We present the design of a multi-layer frequency selective surface (FSS) composed of subwavelength elements, with large harmonic rejection bandwidth. The FSS design is based on an equivalent circuit model, where the inter-layer interaction is only described with a single transmission line representing the fundamental Floquet wave. To ensure the accuracy of this model, we enforce the FSS period to be comparable to the inter-layer distance. The FSS comprises five metal layers and has an overall height of one sixth of the wavelength at the central frequency of operation. The FSS simulated response exhibits good stability over a wide conical incidence range, up to 45 degrees. The FSS is then combined with a wide-scanning connected array of slots to implement an antenna element for phased array applications, with integrated filtering properties.

The design procedure and a comparison with an existing periodic FSS designed to meet the same specifications are provided. This comparison indicates that enhanced performance can be obtained using an aperiodic FSS compared to a periodic FSS.

The proposed configuration consists of three anisotropic inductive sheets, separated by two dielectric spacers. The dispersion curves for the two polarizations are engineered to achieve a broadband, linear phase response. The design procedure maximizes the differential phase bandwidth. The circuit parameters of the design are derived without any optimization. Fractional bandwidths larger than 48.5%, for incident angles up to 30°, are achieved.

REGULAR SESSION PAPERS A Frequency Selective Surface on 175 µm thick quartz with gold trace and unit cell size of 728 µm x 728 µm was proposed in our earlier work for isolating three bands in 50 GHz - 200 GHz range for passive remote sensing. In this work, we present the factors influencing the performance of substrate backed FSS on frequency de-multiplexing. 3D numerical modeling is used to investigate the influence of the thickness of the gold trace and fabrication tolerance on FSS transmission. Scanning electron microscopy (SEM) images confirmed a uniform gold deposition (1.85 µm) across the 35 mm x 35 mm FSS structures with ±2 µm fabrication tolerance on the unit cell dimensions. Continuous wave terahertz measurements of the fabricated samples showed at least 10 dB and 0.5 dB transmission losses in the reflection and transmission bands respectively for TE polarization and varying angle of incidence (0° to 45°).

REGULAR SESSION PAPERS A four element low cross polarization sine corrugated antipodal Fermi tapered slot antenna (AFTSA-SC) based on E-plane array architecture is designed to operate at 60 GHz and to cover the ISM band. The single element antenna is capable of achieving wide bandwidth (55-65 GHz) with a stable gain (~15 dB) and 88 % total radiation efficiency. A 1 × 4 AFTSA-SC array with E-plane array architecture is analyzed comparing conventional and mirrored array structures. These two array structures have better, and improved antenna gain (~ 20 dB), low sidelobe level (SLL), and reduced cross-polarization while maintaining the antenna's stable radiation characteristics. The proposed mirrored array architecture improved the cross polarization level by 16 dB as a result of which the E-plane AFTSA-SC array architecture is capable of achieving a high gain at E-plane with a narrow beamwidth, lower SLL and improved X-Pol than with the H-plane.

REGULAR SESSION PAPERS A new linear approach for support reconstruction of both penetrable and impenetrable objects from the measurements of the scattered fields is introduced and described. The approach takes advantage from the fact that for both high conductivity and dielectric scatterers, induced and 'equivalent' currents can be considered localized on the boundary. Starting from these considerations, an ad hoc compressive sensing inspired inversion approach is formulated to localize and retrieve the shape of the unknown objects without a priori assumptions on them.

REGULAR SESSION PAPERS Over the last years, various new non-invasive methodologies have been proposed for medical imaging. Among them, microwave imaging (MWI) seems to be a promising technique for applications such as stroke detection and breast cancer imaging (BCI). This diagnostic modality is based on measurements of the scattered field outside an imaging domain, in which the object of interest is located. This inverse problem requires strategies such as regularization to increase the stability of the reconstructions. This work presents a method to increase stability based on exploiting the wavelet transform (WT) as a regularization strategy combined with a sparsity-based approach. The proposed technique is based on the theory of compressed sensing (CS) to treat the strong ill-posedness of the non-linear electromagnetic inverse scattering (EIS) problem.

REGULAR SESSION PAPERS In this paper, we describe a novel unmixing algorithm for detecting breast cancer. In this approach, the breast tissue is separated into three components, low water content (LWC), high water content (HWC), and cancerous tissues, and the goal of the optimization procedure is to recover the mixture proportions for each component. By utilizing this approach in a hybrid DBT / NRI system, the unmixing reconstruction process can be posed as a sparse recovery problem, such that compressive sensing (CS) techniques can be employed. A numerical analysis is performed, which demonstrates that cancerous lesions can be detected from their mixture proportion under the appropriate conditions.

The S-parameters measurements are performed inside an anechoic chamber with a vector network analyzer and the measurement configuration is set according to differential microwave imaging concept.

The objective of the research is to lower the resonant frequency of a particular characteristic mode that has the desired radiation pattern, and excite it for radiation. The control can be implemented by loading capacitive and inductive components on top of conducting surfaces. For demonstration purpose, capacitive components are coated on a conducting surface to lower the resonant frequency of a particular characteristic mode, which radiates along the horizontal plane.

CONVENED SESSION PAPERS Compact and low-profile VHF antennas with enhanced bandwidth have a wide spectrum of applications in both commercial and military communication systems. Having both of these criteria in a single antenna, however, is very challenging. In this paper, we demonstrate a method for bandwidth enhancement of vehicle-mounted electrically-small antennas operating in the VHF band. In this method, the vehicle platform is considered to be the major part of the radiating structure, while a meandered monopole antenna is used as a capacitive coupling element to excite a desired set of characteristic modes of the platform. The size of the coupling element is 0.06lambda x 0.06lambda x 0.06lambda, where lambda is the free-space wavelength at the frequency of operation, 60 MHz (ka = 0.47). The proposed approach was employed to successfully enhance the bandwidth of a vehicle-mounted VHF antennas by at least 400%.

CONVENED SESSION PAPERS In this paper, we present an approach to design conformal HF band multi-antenna system for aircraft using the characteristic mode theory. The whole antenna system generates omni-directional radiation pattern at 18 MHz, NVIS radiation pattern at 8 MHz and downward radiation pattern at 28 MHz. The antenna system is realized by a pair of folded monopole exciters embedded on the vertical stabilizers, a pair of probes to excite the long notches cut in the vertical stabilizers, and a pair of folded monopole exciters embedded on the horizontal stabilizers, respectively. Properly designed matching networks are used to match the input impedance of these exciters. The simulated input impedance bandwidth of the three antennas are 1.6%, 7.6%, and 12.5%, respectively. The port isolation is more than 10 dB across the whole interested frequency band. Chenghui Wang 1444233 University of Electronic Science and Technology of China P.R.

CONVENED SESSION PAPERS Ground penetrating radar (GPR) sees a wide range of applications; some investigations, such as assessment of roads and reinforced concrete bridge decks, often employ vehicle mounted GPRs. When mounted on vehicles, GPR can be deployed in an air-launched or ground-coupled form. The trade-offs in GPR performance are seldom discussed and not well understood for the two approaches of deployment. Further, what maximum height is acceptable for being ground-coupled and what is the minimum height to be considered air-launched? Our goal is to study the behaviour of direct air/ground and reflected waves as antennas are moved from being directly on ground to being in air (i.e., at a height off the air-ground interface, where the surface reflection is clearly isolated from the direct signal). We present both numerical simulation results and observed GPR data to study and characterize responses. Results confirm the generally observed behavior and provide insight into the trade-offs.

CONVENED SESSION PAPERS An innovative two-dimensional (2D) inverse scattering (IS) approach for processing Ground Penetrating Radar (GPR) data is presented to retrieve the electromagnetic characteristics of a buried domain. The developed GPR-IS approach exploits a multi-frequency (MF) strategy to deal with the wideband nature of the available measurements and a multi-resolution (MR) scheme to reduce the ratio between problem unknowns and informative data. Moreover, a customized Particle Swarm Optimizer (PSO) is exploited in order to overcome the limitations of deterministic approaches in finding the global optimum of the arising MF cost function, which is characterized by a high density of local minima (i.e., false solutions).

CONVENED SESSION PAPERS Several techniques have been developed to solve the direct scattering problem from targets involving different media and interfaces. For the case of stratified media and embedded targets, different formulations based on integral equations solved with method of moments have been proposed. Time-domain methods have the advantage to return results in the form of radargrams typical of measurements with pulsed techniques. Among them, the Finite-Difference Time-Domain method is widely used due to its high flexibility in the simulation of targets and backgrounds of arbitrary shape. For the case of targets with canonical shape, i.e., circular cross-section cylinders, in a non-homogeneous background, the Cylindrical Wave Approach gives a semi-analytical solution that is fast and accurate.

CONVENED SESSION PAPERS Tomographic approaches represent an emerging way to process GPR data and to investigate stratified media, since they allow to obtain images that are more readable than those achieved with standard data processing, which require human expertise and may show high probability of false alarms. In this contest, an efficient inverse scattering strategy is proposed to achieve dielectric characterization of buried objects in lossy and stratified soils. The approach exploits the framework of the "virtual scattering experiments" in a stratified media, thus allowing to deal with not only the non linearity of the underlying physical phenomena, but also to counteract the difficulty arising from the aspect limited measurement configuration adopted in GPR surveys. The proposed method is tested through a numerical example, by considering Compressive Sensing regularization scheme in order to enhance imaging resolution capabilities.

CONVENED SESSION PAPERS In this work, the implementation of the buried object approach (BOA) to two-dimensional (2-D) and three-dimensional (3-D) scattering problems related to bodies buried under locally rough surfaces is discussed. Here, the scattered field from the buried objects are computed by the method of moments (MoM) based numerical solution of an electric field integral equation (EFIE) involving the Green's function of the background medium. BOA presents a practical way to obtain the electric field and Green's function on the background which consists of half-space with locally rough interface. By this way, the coupling interactions between the rough surface and buried objects are subtly taken into account. BOA method can be applied both 2-D and 3-D scattering problems of buried object under 1-D and 2-D rough surfaces, thoroughly. Various numerical results have been presented to demonstrate the applicability and efficiency of the presented method.

CONVENED SESSION PAPERS This paper deals with the electromagnetic scattering of a plane-wave obliquely incident on a periodic circular cylinder array including heterogeneous cylinders, and shows a spectral-domain formulation based on the recursive transition-matrix algorithm. Generally, the fields in imperfectly periodic structures have continuous spectra in the wavenumber space, and the spectral-domain approaches require an artificial discretization in the wavenumber space. The present formulation also uses a concept of the pseudo-periodic Fourier transform, and the discretization scheme can be considered only inside the Brillouin zone.

There are various possibilities to generate this distribution. A general classification is for example the distinction between direct radiation and radiation via reflecting apertures. The way how the illumination is realised is directly linked to the complexity of the required feed system. Looking back, one can observe a change from small simple feed systems towards large complicated multifeed arrays, back to simple feeds again. Nowadays we again see the request for large feed systems and complex multifeed arrays. In this paper, we present a short history on antenna systems and the corresponding feed systems over the recent decades. An insight on current feed systems and future products is given.

CONVENED SESSION PAPERS A collective Uniform Geometrical Theory of Diffraction (UTD) solution is developed for describing, in a simple fashion, the radiation from a periodic, finite but long, linear array of elemental antennas mounted conformally on a larger canonical circular cylinder geometry which is assumed to be a perfect electric conductor (PEC). This work is relevant to the prediction of the performance of large and conformal electronically scanned phased arrays in modern applications. The collective UTD radiation field of the entire array in the presence of the cylinder, when observed at any point which is not too close to the array, is vividly described here in terms of just three propagating rays; one such ray arrives to an external observation point from an appropriate point within the array interior, while the remaining arrive from each of the two ends of the linear array, respectively.

Transitions from RGW to GGW and vice versa can be advantageously combined leading to very compact feeding networks. Interestingly, these transitions circumvent the 180 deg phase difference in E-plane power splitters, facilitating in-phase corporate feeding networks based on such dividers. Using these transitions a first prototype of a 4x4 single-layer slot array antenna is presented. This antenna exhibits several appealing features for contemporary applications: single-layer, compact, symmetrical, and both radiation pattern bandwidth and impedance bandwidth greater than 14 % at V-band (57-66 GHz).

CONVENED SESSION PAPERS A contactless in-line wideband and low-loss microstrip to groove-gap (GG) waveguide transition based power divider operating at X-band is presented. It can be scaled to mm-wave frequencies and beyond without too many mechanical problems, due to the innovative Gap Waveguide technology. The principle of operation is based on transforming EM fields from a SIW to a groove-gap (GG) waveguide mode via near field electromagnetic coupling. This is advantageous since the proposed solution avoids the use of metal contact between the SIW and one of the waveguide parts. Furthermore, metamaterial-based gap waveguide technology provides a resonance-free packaging solution for the integrated MMIC amplifier. We propose to use this transition in a power divider scheme to provide distributed power amplification in groove-gap (GG) waveguide technology to be applied to antenna systems in this same technology.

The antenna is composed of two substrates, by using the ring slot with a shorted strip on the upper substrate and the EBG textures located on the lower substrate, the circular polarized characteristic of the antenna is obtained, the simulated results with CST simulation software show the antenna has the impedance bandwidth of 13.8% (72.1GHz-82.8GHz, |S11|<-10dB), and the axial ratio is from 75.2GHz-79.9GHz (AR<3dB) with 6% circular polarization bandwidth. And also the microstrip slot antenna is designed and compared with the antenna in this paper. The compared results give the strong evidence that the microstrip-ridge gap waveguide circular polarized slot antenna has wider bandwidth and higher gain. Fangfang Fan 1349613 Xidian University P.R.

CONVENED SESSION PAPERS In this communication, a TE220 mode substrate integrated cavity (SIC) excited 2×2 circularly polarized (CP) antenna subarray for wideband and high-gain W-band array application is presented. This antenna subarray is designed by using of two low-cost double-side printed circuit broads (PCBs). By combining the rectangular slot and L-shaped probe, a CP antenna can be achieved. The transmission loss caused by divider can be reduced by using the high order mode substrate integrated cavity to excite the slot antenna subarray. Furthermore, such use reduces processing difficulty and fabrication cost. To reduce the loss further, the microstrip-based ridge gap waveguide (GWG) technology is applied to feed the SIC subarrays. Moreover, a linear polarization (LP) slot antenna is also designed to illustrate the operation mechanism of the proposed CP antenna. To validate our design, an 8×8 antenna array with 4×4 SIC subarrays has been fabricated and measured. Hao Wang 1244097 Nanjing University of Science & Technology P.R.

CONVENED SESSION PAPERS Novel manufacturing technologies such as additive manufacturing or 3D printing allow many simplifications in the production of electromagnetic components. In this paper we focus on the characteristics of the components based on gap-waveguide technology and manufactured using 3D printing after which chemical copper electro-plating is performed. This is important since gap-waveguides are quite complex structures from manufacturing point of view due to multiple small metallic parts. For this purpose we have designed a groove gap-waveguide demonstrator at 10 GHz and a novel gap-waveguide leaky-wave antenna at 30 GHz which can be easily integrated with both the new gap waveguide and the traditional waveguide technology. Through simulations and measurements we will try to highlight the benefits and problems of this 3D technology in the high-frequency components prototyping.

CONVENED SESSION PAPERS A new simple transition from a microstrip to gap waveguides has been proposed in this paper. The transition has been implemented for ridge gap waveguide and a groove gap waveguide. The cavity coupling is used to couple the waves between the microstrip and the gap waveguides. This cavity acts as a backshort in the transition region and the microstrip lies inside the waveguide, which provides a solution to integration of RF MMIC circuits with the feed-network of the gap waveguide array antenna. Roger 3010 (Er=10.2) was used as the microstrip substrate for these transitions. The optimised back-to-back Ridge Gap Waveguide (RGW)-microstrip transition shows relative bandwidth of 21% for S11<20 dB and Groove Gap Waveguide (GGW)-microstrip transition shows relative bandwidth of 20% for S11<17 dB. The insertion losses are better than 0.5 dB in the designed frequency bands for both the RGW and GGW transitions.

CONVENED SESSION PAPERS In this paper leakage-free contactless flange adapters for mm-wave frequencies are presented. The adapters are compatible with standard rectangular waveguide flanges, covering the whole operational bandwidth of those. They are placed in between standard waveguides in order to avoid leakage at the joints between flange surfaces. Unlike standard flanges, the adapters are contactless, i.e., they do not require to be in good electrical contact when connected to the flange surfaces. Therefore, the use of fastening screws can be replaced by more practical ways of interconnection, e.g., magnets. In the end, the use of such adapters between standard waveguide flanges allows for faster, accurate and reliable mm-wave measurements.

CONVENED SESSION PAPERS The maximum "recoverable" energy of a small radiator is determined. This energy is defined as the maximum energy that can be recovered from the electromagnetic field distribution in entire space generated by the radiator up to the time point considered. It is shown that the concept of recoverable energy for small radiators leads to a quasi-constant future current. The question can be raised whether this "recoverable" energy can be identified with the stored energy for a small radiator. Guy A. E.

CONVENED SESSION PAPERS Optimization of antenna currents is used to determine lower bounds on the Q-factors for antennas. Minimum Q-factors for antennas with specified radiation patterns are reformulated in convex form and are hence easily solvable. Here, it is shown that the unconstrained case with minimum Q can be relaxed to a dual problem that is solved as a generalized eigenvalue problem. This dual problem determines the minimum Q-factors for problems without degenerate eigenvalues. Moreover, cases with degenerate eigenvalues are solved by perturbations of the problems.

CONVENED SESSION PAPERS It is demonstrated by means of RLC circuit models of electrically small antennas that their isolated-resonance quality factors obtained from the "Q-energy" predicts their bandwidths with greater accuracy than the "equivalent-circuit" or the "electrodynamic" energies. Moreover, it is verified that the Q-energy cannot be considered stored energy in highly dispersive lossy material. Nonetheless, using tuning elements containing highly dispersive lossy material, the bandwidth of fifty-percent efficient electrically small dipole antennas can be designed with twice the bandwidth predicted by the Chu lower bound for the quality factor of fifty-percent efficient antennas.

CONVENED SESSION PAPERS In certain communication applications it is advantageous to constrain the shape of the far-field, as to make it act as a spatial filter. This can mitigate interference from other antennas. Such constraints on the far-field behavior, in particular for small antennas tend to increase antenna Q rapidly. To begin to investigate the relation between antenna Q and such far-field bounds, we here consider a case-study with constraint on the partial realized directivity for a two and three parasitic element antenna. The aim is to compare these predictions with a realized parasitic element antenna of the same shape. Note that this paper is a work in progress, and the final comparison between the realized antenna and the fundamental limitations will be discussed at the presentation.

CONVENED SESSION PAPERS A composite antenna of a notch antenna and a loop antenna has been developed for indoor MIMO base station. The composite antenna has dual polarized radiation patterns pointing to two different directions. The horizontally polarized wave is given by the notch element in x-axis direction while the vertically polarized wave is given by the loop element in y-axis direction.

CONVENED SESSION PAPERS We present a novel tightly coupled dipole array (TCDA) that achieves 67:1 bandwidth over the 30 MHz to 2 GHz frequency range. The design is extremely simple, and consists of 3 overlapping dipoles that are fed at 3 different locations to ensure uniform current flow. The overlapping dipoles are "printed" on a 0.3 mm-thick polymer substrate (εr=3), and "sandwiched" between two layers of flexible polymer (εr=3), each 2 cm thick. The TCDA occupies 1.4 m x 0.09 m, and is intended for on-body operation (e.g., placed along the arms). For example, the proposed antenna could be integrated into military uniforms to enhance quality of service in the SINCGARS, Air and Marine, UHF, UHF-Public Safety, and L bands.

CONVENED SESSION PAPERS By augmenting several classes of metamaterial-inspired near-field resonant parasitic (NFRP) electrically small antennas (ESAs) with active (non-Foster) circuits, we have achieved performance characteristics surpassing their fundamental passive bounds. The designs not only have high radiation efficiencies, but they also exhibit large frequency bandwidths, large beam widths, large front-to-back ratios, and high directivities. Furthermore, the various initially theoretical and simulated designs have led to practical realizations. These active NFRP ESAs will be reviewed and recently reported designs will be introduced and discussed.

CONVENED SESSION PAPERS The use of Body Area Networks has been increasing in the past decade due to the emergence of novel wearable and implantable services in the frame of e.g. healthcare, sports, security or fashion. As a result, the number of wearable and implantable antenna designs has exponentially increased in the same time frame. After this first boom in research related to W-BAN antennas, it is now time to learn from the achieved results, and try to understand the mechanisms limiting the performances of such radiators, in order to finally be able to develop useful practical design rules. In this contribution, we introduce a theoretical analysis of some canonical implanted W-BAN electromagnetic source scenarios, using a specifically developed numerical tool based on spherical wave expansions. The obtained results are used to give some design criteria for implantable antennas. Anja K.

REGULAR SESSION PAPERS Fundamental impedance matching bounds for electrically small loop antennas are derived based on spherical wave scattering in the low-frequency limit. A small lossless loop antenna is represented as a two-port network between the excitation port and the fundamental TE spherical wave port. The low-frequency asymptotic expression for the wave reflection coefficient is found and the classical Fano approach is applied to derive integral equalities for the magnitude of the reflection coefficient. A basic loop, one with a series-C element, and one with a parallel-C element are analyzed. The bandwidth upper bounds as functions of the antenna dimension, the port impedance, and the circuit parameters are presented.

RTD oscillators with wide modulation bandwidth (~30 GHz) were fabricated, and wireless data transmissions in the 500-GHz range were demonstrated. An error-free transmission data rate up to 22 Gbps and a transmission with bit error rate less than the forward error correction limit, up to 34 Gbps, were achieved. For alignment-free wireless communication in the polarization direction, an RTD oscillator integrated with a radial line slot antenna for circular-polarized radiation was proposed and fabricated. A sharp directivity and low axial ratio of polarization (2.2 dB) was achieved at 710 GHz.

CONVENED SESSION PAPERS This paper discusses the influence of non-idealities in the analog transmit and receive frontend of an MMIC-based 300 GHz wireless link on the receive signal quality. The degradation of EVM due to limited bandwidth and gain imbalance in the quadrature up- and down-converters is considered and compared to experimentally achieved data. Using adaptive equalization and quadrature error correction in the digital baseband, the measured EVM in a 1 m data transmission is improved by up to 4.5 dB from its raw value and stays below ‑12.75 dB for data rates of up to 36 Gbit/s with QPSK modulation. A frequency dependent theoretical analysis of quadrature gain imbalance allows to derive its impact on receiver EVM as a function of baud rate.

Two different approaches are described and the measurement results for two different probe designs are shown. First, the main reflection center on the wafer probe is determined by analyzing the measured far field radiation pattern at 160 GHz. The second approach is based on an extrapolation measurement of the antenna. It is shown that the reflective areas can be identified for both probe designs. The results can be used to assess the measurement uncertainty and to quantify the measurement error.

CONVENED SESSION PAPERS At millimeter and sub-millimeter wave frequencies, electronic circuits and antennas are often located on the same semiconductor chip to facilitate their interconnection. However, on-chip antennas are characterized by very poor radiation efficiency and extremely narrow bandwidth. This is because they are situated at small electrical distance from a ground plane that shields the antenna from the lossy bulk. High-permittivity superstrates can be located above the antennas to improve the impedance properties, but they support the propagation of surface waves which reduce the efficiency. Here we propose the use of artificial dielectric (AD) superstrates above the antennas to improve significantly their performance. Because of their anisotropy, AD slabs do not support surface waves, thus enabling high-efficiency designs. To clarify the concept, we investigate the property of a simple dipole antenna on chip in terms of impedance and efficiency. Full-wave simulations predict efficiency up to 87% with the presence of the AD.

CONVENED SESSION PAPERS Silicon technologies enable today the development of cost effective millimeter-wave applications (60 GHz wireless link for example). In order to achieve higher data rates (> 10 Gb/s), we can now consider the sub-THz frequencies in order to take advantage of wider frequency bands. In this context, the development of low cost and highly integrated Si-based sub-THz wireless chipset is a hot topic; industrial Si Photonic PIN Photo-Diode can be used as sub-THz source. But a key challenge is the design of antennas and packages able to support ultra-broad band sub-THz transmission in a cost effective manner. We propose here the design of a 200-280 GHz antenna integrated in an organic substrate packaging technology. Simulated performances exhibit a gain of >8 dBi over a 33% bandwidth. A 3D printed plastic lens is then added to the system in order to increase the achievable gain up to 20 dBi.

Each antenna directive beam links a set of users/spectators sitting in the stadium tribune with a central base station. The use of multiple high frequencies line of sight links (120GHz) makes possible wireless data rates of 12Tbps to serve 80.000 users with a reasonable overall radio frequency (RF) power consumption (≈ 50W) and user terminal transmit power (≈15dBm).

The scenarios consist of maximum 4096 transmitter antennas and 500 single antenna users which are at the ground level. The environment is one quarter square kilometre large and consists of 92 buildings with various heights. Channel matrices are obtained using ray tracing simulations. Maximum Ratio Transmission (MRT) and Minimum Mean Square Error (MMSE) linear beamformers are implemented during the post processing. The downlink performances are investigated. The results indicate that the variation of performance among the users can be different even though the average performance figures are not significantly different for the given deployment schemes.

REGULAR SESSION PAPERS An angular distribution of received signals has a significant impact on their spectral and correlational properties. Most of angular dispersion models do not consider antenna patterns. The developed procedure for determining the propagation path parameters enables a wide range of assessment of the impact of the propagation environment on the received signal properties. In contrast to the other models, this procedure is based on a geometrical structure, which parameters are defined on the basis of power delay profile or spectrum This modeling method allows also the power radiation pattern (PRP) of the transmitting antenna. The aim of the paper is to present the influence of the transmitter antenna PRP on the scattering propagation paths that arrive at the receiver.

REGULAR SESSION PAPERS Safety assessment of exposure caused by cellular base stations based on calculation methods is often performed using free space propagation in order to include the worst case. For prospective technologies (e.g. small cells in the vicinity of people), this approach might lead to a high exploitation of exposure limits. This paper investigates the overestimation of downlink exposure being predicted with a free space propagation model in comparison to a deterministic 2D knife edge diffraction model in an urban environment for a rooftop mounted base station. The results show that overestimation is quite low in the vicinity of the base station, particularly in LOS regions. In a distance between 100 and 200 m the overestimation is constantly rising, whereas for distances larger than 200 m it stays nearly constant.

REGULAR SESSION PAPERS Small cells, novel low-powered base stations with local range, are nowadays investigated in order to improve the radio coverage and capacity in macro cell layer. The radio frequency exposure induced in such cells is unknown. Hence, we assess in this paper, through experimental measurements, the impact of an LTE small cell cluster on the radio frequency exposure induced by a mobile handset. With respect to macro cells, we show that the deployment of small cells provides better radio coverage in terms of throughput while minimizing the radio frequency exposure induced by the mobile handset.

REGULAR SESSION PAPERS Studies of the level-crossing rate (LCR) and the average duration of fades (ADF) are so far only devoted to stochastic processes being a function of one independent variable, which is usually time or in some few cases frequency. In this paper, we study the LCR (ADF) of wide-sense stationary uncorrelated scattering (WSSUS) processes in the time-frequency domain. A closed-form solution will be derived for the so-called time-frequency LCR (ADF) of the absolute value of the time-variant transfer function (TVTF) of WSSUS processes. It is shown that the LCR (ADF) is circularly symmetric in the normalized time-frequency domain. The derived time-frequency LCR contains the time LCR and frequency LCR well known in the literature as special cases. The importance of the introduced time-frequency LCR is demonstrated by introducing a new method for the estimation of the Doppler spread and the delay spread from measured TVTFs of WSSUS channels.

REGULAR SESSION PAPERS A large array of dielectric resonator antenna (DRA) based on Electrically-Steerable Parasitic Array Radiator (ESPAR) concept is presented for massive MIMO application. The proposed array consists of 18 sub-arrays while each subarray has three single units. Each single antenna units consist of four driven DRA, coupled to the parasitic DRAs in their E- and H-Planes. All the antenna elements placed in an interleaved arrangement which surpass the grating lobes with better scanning capabilities in all azimuthal directions. With the beam scanning capability feature of each sub-array, the proposed array can be a good candidate for massive MIMO and mm-wave application.

REGULAR SESSION PAPERS The current paper deals with application of leaky feeder cables (LFCs) in linear-cells MIMO systems. We first revisit the method whereby we can map the measured channel data to throughput in an LTE system. Later we show that feeding an LFC from its both ends by two independent signals can potentially lead to a promising 2x2 MIMO system with a desirable throughput. Our results also interestingly demonstrate that feeding an LFC from both ends yields a constant average throughput all along the cable. However, the corresponding average throughput is dependent on the length of the cable and its longitudinal loss. For very long LFCs, the system may also convert to rank one system. We discuss about this case too.

REGULAR SESSION PAPERS An approach for direction-of-arrival estimation is presented that relies on a multibeam antenna. The antenna provides a pre-defined set of radiation patterns with distinct main directions. The approach considers only magnitudes of a received signal after its decomposition by means of a beam-forming network. Its application to measured signals obtained from an experimental setup is discussed, revealing that the resolution of the direction estimated is not limited by the beamwidth of the radiation patterns.

REGULAR SESSION PAPERS The angle-of-arrival estimation algorithm MUSIC using a multibeam antenna was investigated. The antenna is composed of four circularly polarized antenna elements and a beam-forming network, which provides a switchable set of radiation patterns with distinct main lobe directions. Circularly polarized lobes are not affected from random source inclinations in terms of polarization losses. But they have a limited axial ratio beamwidth, being a limitation for direction finding algorithm based on phase difference. This limitation is illustrated and utilizing the MUSIC algorithm. Compensation of the effect of source inclination on the direction of arrival estimation with a multibeam antenna is presented.

REGULAR SESSION PAPERS Physical layer security allows secure communications between a source and destination without the need to resort to key-based encryption techniques. Its increasing importance stems from the difficulty of implementing advanced encryption techniques in certain networks, such as the internet of things (IoT). In this paper, physical layer security is implemented by using massive multiple input multiple output (MIMO) techniques. Specifically, beamforming with large cylindrical antenna arrays is investigated. These arrays allow the transmission of both the useful signal to the destination and the jamming signal to the eavesdropper without resorting to the help of other nodes for relaying the signal and/or jamming the eavesdropper. Simulation results show that high levels of secrecy capacity can be achieved with the proposed approach.

REGULAR SESSION PAPERS In this work, we expose the fine-tuning and validation processes (based on radiometric and radiosounding measurements) of a preiously developed WF-based technique. The latter is a model chain that exploits weather forecasts (WF) for the optimization of deep-space satellite downlink at Ka-band. The presented results confirm the reliability of the WF-based technique and its better performances with respect to more traditional techniques. In terms of yearly-received data-volume, we have found a gain of about 15% to 24% associated with a decrease of the yearly lost data. These results make the proposed WF-based technique actually suitable for planning deep-space satellite-transmissions at Ka-band. Marianna Biscarini 840251 Sapienza University of Rome Italy 1 Frank S.

REGULAR SESSION PAPERS Reliable estimates of satellite channel characteristics are of great importance for satellite communications, especially with use of even higher frequencies as Ka-band and in near future Q- and V-band. At a given rain rate the shape of rain drop size distributions (DSDs) considerably influences the corresponding specific attenuation. In previous work it was shown, that annual DSD statistics give evidence for geographical dependence. In this paper first results indicate that the seasonal variations of the DSD shapes are minor in comparison to the geographical dependencies. This points to a conclusion that a global map of annual DSD statistics will give a valuable contribution to satellite link parameter estimates.

REGULAR SESSION PAPERS The attenuation due to rain is one of the main impairments in satellite communications. It is well known that rain attenuation is dependent on the elevation angle of the link, being more severe at low elevation angles; this has a definite impact on the design of TLC and data download systems based on LEO satellites. This paper presents a simple model to scale long-term rain attenuation statistics as a function of link elevation angle. The model receives as input the known complementary cumulative distribution (CCDF) at a specific elevation and generates the CCDF scaled at other elevation angles.

In this respect, monthly CCDFs of rain attenuation at both RF (28 GHz) and optical bandwidth have been calculated in the area of Hyderabad (Pakistan).

REGULAR SESSION PAPERS Next-generation 5G cellular networks are expected to operate on the millimeter wavelength frequencies (e.g., 28 GHz and 38 GHz) to offer broader bandwidths and higher data rates. In this frequency band, rain is a major impairment to received signal power. This work aims to improve predictions of rain attenuation for 5G wireless networks operating at 28 GHz and 38 GHz in heavy rain regions, by exploiting three years of raindrop size distribution data collected at Kuala Lumpur (Malaysia). The specific attenuation is calculated by means of point matching technique and each minute of DSD data. The empirical relationship between specific attenuation and rainfall intensity are subsequently derived and compared with those for Rec. ITU-R P.838-3 and Singapore results. The results indicate substantial local deviations from the ITU-R model, especially at 38 GHz. These results offer important information for predicting rain attenuation of 5G wireless communication systems in heavy rain regions.

REGULAR SESSION PAPERS An anatomically realistic human head phantom was elaborated for different Larmor frequencies, which allows rapid quantification of B1+ of MRIs of different magnetic fields. The permittivity ε' and conductivity σ of sucrose/salt/agar aqueous solutions of varying concentration was determined; a solution with these components and having the adequate concentration to obtain the brain's dielectric properties at 3 T, 7T and 11.7T was manufactured. An anthropomorphic polymeric skull was filled with this mixture. To check the behavior of this phantom in a MRI configuration, both numerical and experimental validations were done: a B1+ field distribution inside the phantom was calculated with CST Microwave Studio inside a birdcage coil at 7T; the same mapping was assessed in a 7T MRI.

REGULAR SESSION PAPERS Wireless Power Transfer (WPT) technology is one of the most promising application for charging the batteries of electric vehicles. In this framework, the exposure assessment of human body to the stray electromagnetic fields emitted by WPT devices represents a critical issue. In this paper, a methodology for the numerical assessment of the Electric (E)-field induced by WPT systems in exposed people was set up in order to obtain reliable dosimetric results, avoiding high computational costs for simulations. A numerical dosimetric study was carried out to evaluate the electric (E)-field induced in both a homogeneous ellipsoid phantom and in an anatomical human model exposed to a WPT system prototype (delivered power 560 W). Two exposure scenarios were considered employing the anatomical model: the maximum 99th percentile of the induced E-field value in central nervous system was 0.05 V/m and the maximum current density value in the head was 30 mA/m2.

REGULAR SESSION PAPERS Several studies have examined the propagation losses of the Human Body Communication (HBC) channel. However, a general agreement has not be found yet. In this paper, the complete S-matrix of the HBC channel is measured on an human subject using two kinds of electrode devices. The data is integrated in a lumped element model, which allows to take into account for the capacitive return path of realistic battery operated transmitter and receiver. Results, shown as power gain curves between 10 MHz and 150 MHz, exhibit a band pass profile, with cut-off frequency depending on the kind of electrode devices. A model is obtained by vector fitting of the equivalent Z-matrix of the measured HBC channel.

REGULAR SESSION PAPERS Near-field coupling communication (NFCC) is a communication technology that treats the surface of the human body as a transmission path by using a carrier frequency below 10 MHz. Because the radiation signal to a space is suppressed in NFCC, humans wearing an NFCC transceiver (TRX) can exchange personal information through handshaking without having to worry about information leakage. To establish stable personal information exchange, handshaking communication needs to satisfy two requirements relating to the signal propagation loss difference between standing and handshaking postures and the S/N ratio in the handshaking posture. From the equivalent circuit of the handshaking communication, we present the position of the TRXs that satisfy the two requirements. Experimental results revealed that the two requirements are satisfied when NFCC TRXs are inserted into the soles of shoes. As a result, we demonstrated that handshaking communication can be implemented by inserting TRXs into the soles of shoes.

REGULAR SESSION PAPERS In this paper, we study two conceptual antennas of loop and dipole geometries for power coupling in medical implant applications. The coupling between the on-body mounted antenna and the implant antenna is the study scenarios. A sample muscle tissue with the implant antenna of size 40 mm in the depth of 50 mm and wide frequency range of 200-3000 MHz are used for computations. Frequency dependent electromagnetic characteristics of the biological tissue are considered. It is shown, that the coupling between a pair of the loop antennas surpasses the coupling in the other combinations of the loop and dipole for the frequencies below 800 MHz. Also, the on-body loop antenna induces less specific absorption rate (SAR) than the dipole that permits more power injection and thus higher energy transfer to the implant antenna. Furthermore, the size effects of the loop antenna on the power coupling are reported.

REGULAR SESSION PAPERS In the paper a new form of universal polynomial chaos expansion, which was introduced in [1], is applied to numerical stochastic simulations o ultra-wideband (UWB) electromagnetic wave propagation. It is assumed that stochastic parameters of a propagation scenario follow a Gauss distribution. The coefficients of an expansion are analytical functions of a mean and a standard deviation a stochastic variable (scenario parameter), which makes an expansion universal. The necessary initial coefficients have to be calculated numerically only once for a freely chosen values of stochastic variable parameters.

Measurements were conducted using a wideband channel sounder to derive channel parameters such as building penetration losses and channel delay spread values. It was observed that signal attenuation is strongly material-dependent and also, to some extent, frequency-dependent as well. However, the delay spread is weakly correlated with the frequency.

The average RMSE values between the measurements and the two considered models for scenario 1 were 3.09 and 3.51 dB, respectively, while the average RMSE values for scenario 2 were 4.58 and 4.39 dB, respectively. In addition, the proposed models were compared with some existing attenuation models which are applicable at 28 GHz. These results can be used in predicting path loss through vegetated areas at 28 GHz.

REGULAR SESSION PAPERS A wireless channel is always composed of both deterministic and stochastic multi-path components. A high Rician K-factor increases the contribution of deterministic channel components, thereby reducing the significance of stochastic parts of a channel. This paper focus at the investigative analysis of fading depth and K-factor to analyze the deterministic behavior of a channel under a certain bandwidth and propagation setup. It has been observed that small scale fading depth asymptotically converges towards zero dB whereby K-factor increases with bandwidth. Results also show that the de-polarization of a signal increases its amplitude fading. This effect is much more significant at lower bandwidths but an increase in bandwidth reduces the difference in fade depths between polarized and depolarized signals. These observations lead to a conclusion that channel tend to be more deterministic at higher bandwidths.

REGULAR SESSION PAPERS In this paper, by equipping with omni-directional antennas and high gain power amplifier in our channel sounder system, the propagation characteristics which de-embed antenna response at 28GHz and 38.6 GHz are analyzed. The base station height-dependent path loss model is derived by the channel measurement in non-line-of-sight (NLOS) urban micro outdoor scenarios. Furthermore, the path loss models at 28G and 38.6G Hz are compared with the path loss model at 3.5G. Also，the proposed path loss model is compared with 3GPP 38.900 path loss model, and it can be found that 3GPP will overestimate the system performance since the 3GPP model has lower path loss. Finally, some preliminary research on the shadowing effect of human body and vegetation are presented. Zhimeng Zhong 1448709 Huawei Technologies Co., Ltd. P.R.

REGULAR SESSION PAPERS The performance of GPS in densely built urban areas is greatly undermined due to multipath propagation. Therefore, we propose a propagation model which is used to obtain 'location fingerprints' with the aid of modern computers thanks to their growing processing power. At the heart of the technique is the use of a ray-launching model from which a database is generated containing propagation parameters such as received signal strength, time of arrival and angle of arrival as a function of source and receiver location. These are then mapped with physical locations using an artificial neural network. Besides, a sequence based tracking tool is proposed to assist navigation with minimal communication required between mobile device and database. This paper details the generation of a database for real world geometries read from OpenStreetMap and the development of a localisation algorithm.

REGULAR SESSION PAPERS This paper explores the effect of increasing number of receivers to evaluate the geographic location of the High Frequency (HF) transmitters for distances in the radius of 2000 km. In the case of HF propagation over long distances, signals propagate using skywaves and are reflected back to the earth from the ionosphere. The Quasi-Parabolic (QP) model of the ionosphere provides analytic equations for ray path parameters through which the signal travel time is obtained. The position of the transmitter is found using time domain HF geolocation method namely Time Difference of Arrival (TDoA). An analysis of the QP model of the ionosphere is provided and limits of the model are emphasized. The geolocation algorithm for TDoA along with its mathematical equation is explained. Simulation results demonstrate that increasing the number of receivers leads to a significant improvement in the geolocation accuracy.

The method is able to estimate all three Euler angles required to describe the relative attitude, in contrast to prior methods that place severe limits on what can be estimated. Initial simulations based on the algorithm reveal that the estimation errors are relatively small even for moderate signal-to-noise ratios.

REGULAR SESSION PAPERS This work proposes the utilization of the Reflect Array (RA) antenna in the reader of the Frequency Coded (FC) chipless RFID systems aiming at increasing the reading range, minimizing the environmental reflections and acquiring a lot of novel capabilities that can not be provided by the conventional antenna systems. The presented RA antenna operates over UWB range of frequencies from 4 to 6 GHz fulfilling the requirements of the FC chipless RFID systems. Furthermore, the RA antenna beam is 4 times narrower than the feeder beam and thus 6 dB higher in gain with -10 dB SLL. Therefore, this developed UWB RA antenna is successfully integrated with the FC chipless RFID tags and a reading range of 1 m is attained. To the best of the author knowledge, this is the highest reading range achieved in the FC chipless RFID systems, considering real-world indoor environment and software defined radio reader.

REGULAR SESSION PAPERS In this paper, we propose a novel energy detection (ED) receiver architecture combined with time-of-arrival (TOA) estimation algorithm, compliant to the IEEE 802.15.4a standard. The architecture is based on double overlapping integrators and a sliding correlator. It exploits a series of ternary preamble sequences with perfect autocorrelation property. This property ensures coding gain which allows an accurate estimation of power delay profile (PDP). To improve TOA estimation, the interpolation of PDP samples is proposed and the architecture is validated by using an ultra-wideband (UWB) signals measurements platform. These measurements are carried out in line-of-sight (LOS) multipath environment. The experimental results show that the ranging performances obtained by the proposed architecture are higher than those obtained by the conventional architecture based on a single-integrator.

REGULAR SESSION PAPERS This paper presents a high-gain 6-40 GHz circularly polarized antenna system designed for a 6U CubeSAT mission for monitoring RF emission from earth. The antenna system consists of three quasi-tapered helical antenna elements, operating at 6-11 GHz, 11-22 GHz and 21-40 GHz, respectively. Each antenna element is designed to produce an end-fire beam with its helical diameter varying along its axis to achieve a linearly increasing gain from 12 dBic gain at 6 GHz to 20 dBic at 40 GHz. The close proximity of the antennas causes strong mutual coupling and pattern distortion. This problem is alleviated by carefully arranging the antenna positions, the utilization of different circular polarization (CP) handedness, as well as loading of the radome.

REGULAR SESSION PAPERS In this paper we provide a simple and accurate physical picture of the antenna reception mechanism. Specifically we introduce the concept of the observable field. This is the portion of the incident field that can be received by an ideal antenna located in a given region of space. Thus this field defines the available power, and provides clear guidelines into the design of such ideal antenna. The observable field is composed by two complementary inward and outward propagating spherical waves whose amplitude can be calculated, without introducing spherical wave vector modes, simply via the equivalence theorem. This methodology is derived here for a single plane wave but it can be easily extended to multiple coherent plane waves.

REGULAR SESSION PAPERS We report an RF study at 50 GHz of the Ice Cloud Imager, consisting of a parabolic reflector inside a semi-closed sun shield, as obtained with full-wave method of moments (MoM) and the asymptotic high-frequency multi-geometrical theory of diffraction (Multi-GTD) method. The Multi-GTD results accurately reproduce details of the main beam and sidelobes originating from focusing, but fail to predict other parts of the pattern that are due to a large number of scattering events inside the semi-closed sun shield. MoM results at the half and double frequency (25 and 100 GHz) show that the parts of the pattern that are not well described by Multi-GTD, but still within the dynamic MoM range, remain at the same overall level as the frequency is varied. Thus, when analyzing at higher frequencies of interest (> 183 GHz), a complementary MoM and Multi-GTD approach can be adopted to predict the radiation pattern.

A planar radiating aperture-fed microstrip antenna is used to guarantee the low profile of the proposed element. To reduce the losses and mutual coupling, a novel antenna element similar to the cavity-backed Strip-Slot-Air-Inverted Patch (SSAIP) is proposed as an element of designed array of 81 elements. Wide-angle scanning up to 60o is achieved at both frequency bands of the operation.

REGULAR SESSION PAPERS A novel TM01 to TE11 mode converter with aligned ports, wide bandwidth and high conversion efficiency is proposed. Mode conversion is performed with a circular waveguide partitioned into two semicircular sections with different path length. Lower semicircular section has a cosine profile to provide a path difference of lambda_g/2 for the mode conversion. Mode converter was designed and simulated at 3 GHz operating frequency. Electric field calculation shows that the mode converter can handle up to 3 GW high power microwave pulse signal. The mode converter was fabricated and the mode conversion was verified experimentally, by measuring far-field radiation pattern of the output mode. The proposed mode converter has a symmetric structure and has the advantage of aligned ports and wide bandwidth.

INVITED SESSION PAPERS Vehicles and other road users will be linked to each other and the road infrastructure to make traffic more efficient, cleaner, and safer. For example, Vehicle-To-Vehicle (V2V) and Vehicle-To-Infrastructure (V2I) communication enables cooperation and intelligent route management in transport networks. To achieve these ambitious goals, wireless links must become dependable: The information relevant for intelligent transport systems (ITS) shall be shared reliably within a tolerated latency. Challenges for cooperative ITS are posed by nonstationary time-frequency-selective fading processes in vehicular channels. Fortunately, the nonstationary vehicular fading may be characterized by assuming local stationarity for a finite region in the time-frequency plane. Thus, we characterize the channel by a local scattering function (LSF). High delay spreads are observed for rich scattering and high Doppler spreads characterize drive-by scenarios. These channel characteristics translate into packet error sequences exhibiting dependencies. Finally, we discuss packet error models of low complexity for large-scale cooperative ITS emulation.

INVITED SESSION PAPERS Antenna design can be considered as an art of shaping and choosing materials to produce a desired current distribution on the antenna structure. Antenna current optimization is a tool to determine an optimal current distribution which can be used for physical understanding, as a priori estimates of the possibilities to design antennas, physical bounds, and as figures of merits for antenna designs. Antenna current optimization is particularly useful for small antennas for which the Q-factor and stored energy are of primary importance. In this presentation, antenna current optimization and stored electromagnetic energy expressions are reviewed. A tutorial description of the steps used to determine the lower bounds on the Q-factor for arbitrarily shaped structures and structures embedded in metallic structures are presented. Moreover, it is demonstrated how the approach can be modified to handle lossy and dispersive materials as well as antenna quantities such as efficiency, gain, directivity, and capacity.

REGULAR SESSION PAPERS This contribution describes the design of a multi-beam dual reflectarray antenna for operation in transmission in Ka-band (20 GHz). The bifocal design concept has been used to obtain an improved performance for the off-axis beams with respect to the single focused antenna. The required phase-shift distributions are initially obtained with the reflectarrays in parallel planes, and then adjusted to compensate the tilting of both reflectarrays in the final Cassegrain configuration. The simulated radiation patterns in the elevation and azimuth orthogonal planes have been calculated for the two beams generated by the focuses, and then the multi-beam performance of the antenna has been evaluated.

CONVENED SESSION PAPERS The inter-element distance in superdirective arrays is usually very small and hence the mutual coupling is considerably high. Consequently, these arrays present relatively low efficiencies. In this paper, we propose using decoupling techniques for reducing the mutual coupling, and hence increasing the efficiency, in this kind of arrays. The concept is proven by full wave simulations of two different Electrically Small Antenna (ESA)-based two-element arrays with an inter-element distance of 0.1λ. In the first array with a ka = 0.56, the original (before decoupling) radiation efficiency of 7% is increased to 13.4% and the realized gain is increased from −6.4dBi to −2.6dBi. In the second array with a ka = 1.18, the original radiation efficiency of 52.1% is increased to 63.7% and the realized gain is increased from 3dBi to 3.9dBi.

CONVENED SESSION PAPERS A concept of modular textile antennas based on commercial snap-on buttons has been recently proposed for wearable applications. This concept has been demonstrated to provide passive system reconfigurabilities in resonance frequency, polarization and/or radiation characteristics using a common feeding structure as a base. In this paper, as a further illustration of the versatility of the modular concept, a circular patch module with a rectangular flap cut in the middle is proposed. This module can provide interchangeability between right-handed circular polarization (RHCP), left-handed circular polarization (LHCP) and linear polarization (LP), as well as passive reconfigurability in resonance frequency for LP, through simple module rotation and different flap configurations (opened or closed).

CONVENED SESSION PAPERS We examine the performance of an implantable antenna combined with a rectifier circuit (Rectenna) in terms of polarization stability, effect of surrounding tissue electrical properties and implantation depth. A single-layer Planar Inverted F-Antenna (PIFA) that exhibits dual-resonance for data telemetry (MedRadio band, 402 MHz) and power transfer (ISM band, 915 MHz) is employed. Antenna polarization is investigated through axial ratio computations. Further, we consider nine tissue-dielectric scenarios comprising ±5% and ±10% variations in the initial tissue permittivity and conductivity. Subsequently, the antenna implantation depth is, also, altered. Indeed, proposed implantable antenna is robust with regards to reliability of wireless link, resonance response and radiation performance. Finally, an improved, previously presented, rectifier system is presented. As shown, its efficiency reaches almost 40% (20% increase) for an optimum load RL=9.5 kOhm at a reference power level Pr=-16 dBm.

CONVENED SESSION PAPERS In this paper, we present an optimized design of an energy harvesting device that converts the arterial wall pulsation to electrical energy and we demonstrate its feasibility to function as a sensor for cardiovascular system monitoring. The device is based on electromagnetic induction and is composed of a coil that pulsates with the artery inside the magnetic field produced by two permanent magnets. In order to validate the proposed concept and evaluate the device's performance, an experimental setup that mimics blood flow and arterial wall movement was constructed. In-vitro experiments indicated that proper optimization can increase the device's produced power and voltage, and that the output voltage of the coil is associated with heart rate, blood pressure, arterial wall velocity and deformation.

REGULAR SESSION PAPERS This paper presents the wireless transmission properties for brick walls with different thicknesses and facade finish coatings. The ceramic hollowed bricks under study are traditionally employed in the Iberian residential construction, where the 11, 15 and 20 cm thicknesses are most common in indoor and outdoor walls. For each brick dimension, three different prototypes were manufactured varying in the type of wall finish, i.e.: naked brick, smooth painted plaster and rough painted plaster. The prototypes were measured in an anechoic chamber at frequencies ranging from 680MHz up to 10GHz. Results demonstrate that the brick wall internal heterogeneity, as well as the type of finish, significantly influence the frequency response of the walls.

REGULAR SESSION PAPERS When the array apeture increases to a huge extent (e.g. tens to hundreds of wavelengths), and the distances between transmitter, scatterers, and receiver are small, conventional plane-wave model cannot be used to characterize the impinging wave accurately anymore. To avoid model mismatch during estimation, in this paper, we use spherical-wave model as the generic signal model, and estimate parameters of multipath component (MPC) with a maximum likelihood method for indoor line-of-sight (LoS) and Obstructed LoS (OLoS) scenarios. The estimated MPCs are reconstructed in the physical environment using a simple geometric method. Comparison with plane-wave model was also conducted to investigate the necessarity of spherical-wave model.

REGULAR SESSION PAPERS This paper analyzes polarimetric characteristics of power delay profiles, cross polarization discrimination (XPD), and received power of specular and diffuse multipath components of MIMO radio channels at 2.45 GHz. Measurements were done in a residential house at two floors levels: ``same floor'' and ``cross floor''. Variations of 5 to 15~dB in PDPs between co-and cross-polar links were found in the same floor level; however these changes decrease as links go from line-of-sight to non-line-of-sight. XPDs of the radio waves were found to be higher for the cross floor configuration, about 5~dB in horizontally and 7~dB in vertically polarized waves. Also, diffuse components of the radio channels were less affected in cross-polar subchannels compared to that of specular components in the same floor level. The results demonstrate the contribution of diffuse components to the total channel power is higher than previously presented studies for indoor environments.

REGULAR SESSION PAPERS Directional beamforming can increase the network capacity significantly with spatial multiplexing, especially for the hot spots such as airport, shopping malls, and stadiums. Accurate characterization and models of the spatial propagation in such indoor environments are required. In this paper, a 3-dimensional MIMO channel measurement campaign in a large gymnasium is presented. A wideband sounder equipped with two dual-polarized crossed linear arrays was used and the transceivers were placed at different positions on the stands. The azimuth and elevation power spectrum and root-mean-square angular spread of arrival (ASA/ESA) of the multipath components were measured. The normal and lognormal distribution models are proposed for the angular power spectra and angular spreads, respectively. Finally it is demonstrated that the angular spreads have no tendency with respect to the transceiver positions. The measurement results can support the design of the directional transmission technologies for spatial multiplexing in indoor hot-spot scenarios. Zhimeng Zhong 1448709 Huawei Technologies Co., Ltd.

REGULAR SESSION PAPERS Plasmonic coatings could be a solution to the design of stealthy targets over the microwave range. In this communication, Perfectly Electrically Conducting spheres with plasmonic coatings are studied. Two main issues are raised. As the exact computation of the Radar Cross Section (RCS) of finely textured targets with overall dimensions greater than the wavelength of interest often leads to high CPU time consumption, an effective medium approximation correctly describing the electromagnetic behaviour of the coating is suggested. The resulting approximated RCS computations are in good agreement with the exact full wave solution over a broad range of microwave frequencies. Afterwards, a textured spherical metallic target was designed and manufactured. Relying on computer-aided additive manufacturing, a periodically grooved metallic sphere has been realized successfully. Eventually, as we shall see, experimental RCS measurements of a periodically grooved metal sphere and the corresponding theoretical computations compare fairly well.

REGULAR SESSION PAPERS A water-based dynamically tunable microwave metasurface is developed and experimentally investigated. A simple approach to tune the metasurface properties by changing the shape of water-based unit cells by gravitation force is proposed. The transmission spectra of the metasurface for linear and circular polarizations of the incident wave are numerically simulated and experimentally measured under the metasurface rotation around a horizontal axis. The measured changes of the transmission coefficient magnitude up to 8 dB at 1.25 GHz are reported while rotating the metasurface by the 90 degree angle. The proposed approach can be used to design cheap metasurfaces for electromagnetic wave control in the microwave frequency range.

REGULAR SESSION PAPERS We propose a novel leaky-wave antenna configuration which consists of a parallel-plate waveguide with the top plate being a bianisotropic Huygens' metasurface of the omega type. By using closed-form expressions for the metasurface design and after a valid stipulation of the fields below and above it, we are able to design a passive and lossless metasurface that achieves the desired field transformation. The theoretical formulation highlights that we have practically all possible degrees of freedom in the stipulation of the input and output fields. In this way, several examples show that we can arbitrarily choose the output angle, the constant leakage factor and the waveguide height. Elena Abdo-Sánchez 546437 University of Málaga & E. T. S. I.

REGULAR SESSION PAPERS A 60 GHz operating Bull's-Eye (BE) antenna with wide corrugations and a soft-surface is numerically and experimentally analyzed. The employment of wide grooves, rather than narrow grooves, allows a high enhancement of the gain, whereas the inclusion of the soft surface, reduces the side lobe level as well as the backward radiation. A BE with narrow corrugations was also simulated for the purpose of comparison. Fabricated antenna shows a gain of 20.3dB which, due to its reduced dimensions, corresponds to a high aperture efficiency ea = 32%. Furthermore, -13.2 dB side lobe level and 10.4 deg beamwidth are observed.

REGULAR SESSION PAPERS Despite their low profile and competitive radiation characteristics, most of the devices in the corrugated leaky wave antenna family feature an unnecessary excess weight which result detrimental for current innovative applications, such as unmanned aerial vehicles (UAV), aircrafts or satellite antennas. Stereolitography, accompanied by plating, is presented as an economic and fast solution for the manufacturing of lightweight devices, which at the same time is able to overcome traditional metal drilling/spark erosion manufacturing limitations. Here we present an elliptical Bull's-Eye antenna operating at 96 GHz fabricated following a 3D-printing and copper coating process. Due to the off-centered grooves, a tilted beam pointing at 16.5º is obtained, presenting a gain of 17 dB and 3.5 beamwidth.This prototype results of interest for point-to-point communications where direct front side view is not possible, as well as for applications where lightweight and cost-effective antennas are needed, such as satellite communications or deployed in UAV's.

REGULAR SESSION PAPERS The following contribution presents the design of waveguide fed antennas that are directly integrable into injection molded plastic parts using 3D molded interconnect devices technology. The fabrication method used for 3D metallization of the plastic parts is Laser Direct Structuring (LDS). First a single dielectric filled waveguide fed horn antenna is developed, fabricated and characterized to verify the LDS process. The results show a good match between simulated and measured data proving the principle suitability of the LDS process. Based on this the approach of integrating this type of antenna directly into plastic parts is discussed. As an example a dielectric horn antenna is integrated into a generic plastic part and evaluated based on field simulations. The antenna is developed to operate in the frequency range of the WiFi IEEE 802.11ad standard.

REGULAR SESSION PAPERS A major drawback of current millimeter wave technologies used for integration of phased arrays on a chip is low efficiency (5-10%) and consequently low realized gain. In this work, we present integrated antenna arrays on silicon that exhibit radiation efficiency of >80% at 60 GHz. This is achieved by suspending the radiating elements of a phased array in air using micro-electro-mechanical (MEMS) processes, effectively replacing a lossy silicon substrate (under each element) with air. In the latest design we used capacitive feeding with pin and patch height of 40 and 60 µm, respectively. Finite element simulation results verify the performance of the array. A finite array with 5×5 elements achieved -10-dB bandwidth of 1.7 GHz. Array is well matched at 60 GHz with S11<−19 dB. Maximum realized gain (at broadside) is 20 dBi with sidelobe level of -13.3 dB. The efficiency is calculated to be 89%.

REGULAR SESSION PAPERS a flexible RFID-Helix antenna wrapped around the power-cord, integrated with a RFID tag and a current impulse detection circuit, for wireless sensing of the activity of home electrical devices, is proposed. While the use of a straight dipole showed a significant distortion of the antenna radiation pattern due to the very close proximity of the wires inside the power cord, the use of a helical dipole reduces significantly the coupling to the power cord. Furthermore, the antenna coupling to the impulse current arising at the switch ON/OFF of the electrical device, required by the application, is improved and the overall size of the antenna reduced. A realized prototype of the impulse sensing RFID tag using the designed helix-dipole antenna wrapped around the cord demonstrated a sensing range of 7-8 m with a standard RFID reader operating in the US 915 MHz RFID band.

REGULAR SESSION PAPERS In this paper, two chipless solutions dedicated to the authentication of manufactured products are proposed. One device is operating in the RF domain while the other used terahertz (THz) waves. The concept of chipless RFID is extended to authentication where each tag has to present a unique signature that can never be reproduced even if someone try to copy the tag. Both approaches use Electromagnetic (EM) wave as a tool for non-invasive and non-destructive authentication of items. The results show that it is possible to discriminate RF, respectively THz, signatures obtained from devices whose differences of geometrical parameters are as small as tens of micrometers, respectively several micrometers in the THz domain.

REGULAR SESSION PAPERS Graphene is a monolayer of carbon atoms with remarkable electronic and mechanical properties amenable to sensor applications. While the plasmonic nature of graphene at terahertz frequency has been widely reported, investigations on the practical utility of graphene at the microwave frequencies used in wireless sensor nodes are sparse. In this paper, a printed RF slot ring resonator is configured with a graphene thin-film for sensor application. The graphene sensing element comprising the slot ring can be integrated with control electronics as a passive wireless sensor node, but the sensor aspect is not addressed in this paper. The novelty of the paper is that RF losses are minimized by capacitively loading the ring at selective locations along its periphery. Dielectric spectroscopy is used to study variation in surface impedance of the film for various graphene loadings, and RF simulations are corroborated with measurements on graphene loaded slot ring resonators.

REGULAR SESSION PAPERS In this study, a wireless and passive displacement/ strain sensing system is proposed for structural health monitoring (SHM). The wireless and passive interrogation of the sensing unit [a variant of a nested split-ring resonator (NSRR)] is achieved through the near-field interaction and electromagnetic coupling between the single antenna in the system and the multiple sensors called the NSRR probes. It is demonstrated that the system can acquire data from more than one NSRR probe simultaneously in a real-life scenario, where the probes are confined within concrete inside a beam, while the antenna monitors them from outside.

REGULAR SESSION PAPERS State-of-the-art millimeter wave (MMW) multiple-input, multiple-output (MIMO) frequency-modulated continuous-wave (FMCW) radars allow high precision direction of arrival (DOA) estimation with an optimized antenna aperture size [1]. Typically, these systems operate using a single polarization. Fully polarimetric radars on the other hand are used to obtain the polarimetric scattering matrix (S-matrix) and extract polarimetric scattering information that otherwise remains concealed [2]. Combining both approaches by assembly of a dual-polarized waveguide antenna and a 77GHz MIMO FMCW radar system results in the fully polarimetric MIMO radar system presented in this paper. By applying a MIMO-adapted version of the isolated antenna calibration technique (IACT) from [3], the radar system is calibrated and laboratory measurements of different canonical objects such as spheres, plates, dihedrals and trihedrals are performed. A statistical evaluation of these measurement results demonstrates the usability of the approach and shows that basic polarimetric scattering phenomena are reliably identified.

REGULAR SESSION PAPERS Radar techniques have been used recently to monitor bats when they are hunting close to wind energy plants. However, the real-time detection of bats is a challenge and activity metrics must be defined that enable a robust bat detection. In this paper we report on FMCW radar measurements at 24 GHz of Seba's short-tailed fruit bats (Carollia perspicillata) in a laboratory flight tunnel. Experiments have been performed with a single flying bat and multiple simultaneously flying bats. We introduce several activity metrics and discuss their properties. Further signal processing results, such as Range-Doppler maps, will be presented and discussed.

By means of two indoor measurement campaigns performed using millimeter-waves massive arrays in a corridor and in an office room, we show the feasibility of the proposed approach and we compared its performance to those of methods already available in the state of the art.

REGULAR SESSION PAPERS A novel processing algorithm for multiple elevation beam (MEB) synthetic aperture radar (SAR) systems is presented. MEB SAR is a promising technique to reduce the onboard data amount, and its key processing procedure is subpulse separation which is affected by the topography. In this paper, the echoes received by multiple elevation channels (MEC) are regarded as signals coming from different direction-of-arrive (DOA) angles. Then, the subpulse separation is transformed to DOA estimation. Considering the sparsity of the received signals in spatial domain, the sparse-based DOA estimation algorithm is adopted. After obtaining the DOA angles, the overlapped subpulses are separated. The algorithm can also be applied to other MEC SAR systems. Finally, the effectiveness of the proposed algorithm is confirmed in simulations. Taoli Yang 1354397 UESTC P.R. China 1 Donglin Li 1445514 Shanghai Institute of Satellite Engineering P.R.

REGULAR SESSION PAPERS Simulated Quiet Zone (QZ) performance of a designed Compact Antenna Test Range (CATR) is validated by QZ field probing. Simulations of CATRs, however, lack of modeling the probe. The receiving antenna which is used in order to evaluate the field in the QZ has an influence on the calculated / measured co- and cross-polar components. The degree of the effect depends on the radiation characteristic and on the cross-polarization purity of the probe. Including the probe into simulations overcomes the disadvantages of probe correction since the possibility exists to calculate arbitrary dimensions of the QZ. To determine the extent, three probes are characterized and used during field-probing measurements at a frequency of 4.5 GHz. Subsequently, simulated QZ data is generated using a single-reflector model in combination with the multi-level fast multipole method implemented in FEKO. The measured probe patterns are included into the calculated data by applying planar near-field theory.

The CATR simulated in this work is similar to the installed facility at the Microwaves and Radar Institute at the German Aerospace Center (DLR) in Oberpfaffenhofen and it has a dual reflector configuration.

REGULAR SESSION PAPERS A new Compact Antenna Test Range, for EW-antenna system production measurements, is presented. The test object is an active, complex antenna system with several low-gain elements as well as an AESA. The focus in the design of the range was to be able to handle efficient production measurements for this advanced, broadband, test object. To facilitate this, the range is highly automated, which makes it possible to measure several frequency bands, Tx/Rx mode, and test object states in an automated sequence. Test object access and handling was also a key parameter in the range design. Special care was taken to minimize disturbances from the turn tables by recessing the azimuth and slide positioners in a pit in the floor. This is especially important for accurate measurements and interferometry calibration of the low-gain antenna elements.

REGULAR SESSION PAPERS A low-cost reflector used in large-scale compact antenna test range (CATR) with Φ6.0m quiet zone and 0.5~110GHz operating frequency is developed. Firstly, the geometry dimension, dividing scheme and structure form of the reflector are designed according to electrical requirements. Then, vacuum forming based on reconfigurable discrete nail mould (RDNM) is developed to rapidly and low-costly manufacture high-accuracy reflector with honeycomb sandwich structure. Due to extra-large area, the whole reflector is divided into many small panels to be fabricated separately. Meanwhile, steel framework and adjustment mechanism are designed to install and adjust all these panels. Then, a closed-loop adjustment system is constructed by adjustment mechanism and commercial laser tracker to adjust and align all these panels on site. Through final alignment, the root mean square (RMS) of surface error of the whole reflector comes up to 28𝛍m. Wang Mingming 1443208 Beihang University P.R.

REGULAR SESSION PAPERS This paper presents the detailed experimental characterization of X-band 400-element transmitarray antennas in dual linear polarization. The latter can radiate two different and independent beams in two distinct directions with orthogonal polarizations. Two prototypes are designed and fabricated at 10 GHz; one with two beams radiating at boresight, and one designed for two beams pointing in a different direction in each polarization. A 3-dB gain bandwidth of 20% is reached for both polarizations and maximum gain is over 25 dBi for broadside beam.

REGULAR SESSION PAPERS Having a robust architecture against tolerances is one of the most important aspects in high frequency antenna design. In this paper, the effect of fabrication errors on the power pattern of reflectarray antenna is investigated. The uncertainty on the actual size of the patch width is modeled with the interval values. The rules of Interval Arithmetic are then exploited to compute the bounds of the deviation in the resonance frequency, the reflection phase of each element and the radiated power pattern. Due to the redundancy of the Interval Analysis in complex domain, Minkowski sum is implemented to perform the summation. We show that the Minkowski-based Interval Analysis can produce a narrower and inclusive bound. To guarantee the validity of the model, a Monte Carlo test has been carried out to cover the Interval- Minkowski bounds.

REGULAR SESSION PAPERS This paper proposes a design methodology to improve the Artificial Neural Networks modeling of reflectarray cells with regards to the prediction of reflection coefficients magnitude. It is applied to model both types of RA cells (capacitive and inductive) with 5 inputs parameters. The results demonstrate that the final ANNs models are reliable and accurate with an average error on the reflection coefficient magnitude of the scattering matrix (|R11|) of -66dB and -69dB respectively for the capacitive and inductive cells. This accurate prediction of magnitude allows rejecting a priori any cell with loss exceeding a prescribed threshold. Comparison of two canonical reflectarray layouts shows the benefit that could be expected in a synthesis process.

A continuous phase range is obtained by loading patches with varactor diodes on the outer layers of a printed circuit board (PCB) while the signal couples through slots in the inner layers. The design, numerical and experimental characterization of the unit-cell in a rectangular WR-42 waveguide are reported.

REGULAR SESSION PAPERS A novel Phoenix cell for large band reflectarray antennas is presented here. The cell starts with a simple square patch whose phase shift is controlled by its sides' length. The size of the patch is then fixed and open-stubs with variable length are connected to it. To complete the phase range at the central frequency, the stub-loaded patch then shrinks gradually until it disappears completely allowing the cell to rebirth. The cell is characterized by a phase range of 360˚ at the central frequency, linear phase responses with respect to frequency and a reduced phase dispersion of less than 34˚/GHz within a 40% bandwidth. The suggested cell retains the same bandwidth when accounting for incidence angles of up to 30˚ and a reduced bandwidth of 32% accounting for higher incidence angles of up to 45˚.

REGULAR SESSION PAPERS The precise localization of an injured person in a forest environment can be made owing to his cell phone by deploying a dedicated direction finding equipment in the search zone and placed onboard either a vehicle or a drone. The localization accuracy being strongly dependent on the propagation channel characteristics, measurements have been carried out with a MIMO channel sounder at a center frequency of 1.35 GHz and with an 80 MHz bandwidth. Each array element is a dual-polarized patch antenna allowing a multidimensional polarimetric estimation of the channel. The receiving array is below or over the canopy when onboard a vehicle or at different altitudes when onboard a drone. Path loss, delay spread and coherence bandwidth are studied for different relative orientations of the antennas, including co- and cross-polarization configurations. Directions of arrival of the rays are deduced from the MIMO matrix owing to a high resolution algorithm.

REGULAR SESSION PAPERS In this paper, we present a simple and complete simulation approach to compare antenna performance within the frame of Vehicle-to-Vehicle (V2V) communication systems. A geometry-based stochastic channel model (GBSCM) is used to simulate propagation channel pertaining to main environments in a V2V context. Once propagation scenarios are simulated, they are combined with the integration of various antenna locations and patterns. Finally, their performance can be analyzed in terms of Bit Error Rate (BER) or Packet Error Rate (PER) after the implementation of the physical layer (PHY layer) following the IEEE 802.11p standard dedicated to V2X communications.

REGULAR SESSION PAPERS More and more radio systems are incorporated in modern automobiles e.g. multiple mobile communication standards for car-to-car or car-to-infrastructure communications like LTE, ITS G5, satellite navigation, radar detection, and so on. These complex systems need to be tested extensively and under realistic conditions. This paper discusses a modular approach for antenna constellations for over-the-air tests in the virtual road simulation and test area (VISTA) of the Thuringian Center of Innovation in Mobility at the Technische Universität Ilmenau. The goal is to reproduce multipath clusters, in terms of the angular spread of arrival and, as a consequence, the spatial correlation of received signals, as a key parameter of mobile communication channels. This paper amplifies the scope of current research on modular antenna configurations and analyzes the influence of array design parameters on the spatial correlation and, hence, on their suitability for reliable channel emulation.

REGULAR SESSION PAPERS This paper describes a reliable methodology for radar cross section (RCS) measurement of complex small and large targets in the W band. The backscattering behavior of a small car model was measured in an anechoic chamber along with various automotive related targets in a wide gymnasium. Experimental performance in the anechoic chamber is compared to the simulation results. Our simulation model is based on deterministic scattering centers, determined by high frequency approaches, like the physical optics (PO) and the physical theory of diffraction (PTD). Nevertheless, simulations of realistic large objects are both time consuming and difficult to implement. The proposed measurement configuration enables the extraction of non-predetermined scattering points for large object modeling which will significantly decrease the simulation time for road scenarios in radar applications.

REGULAR SESSION PAPERS For the LTE standard using multiple-input multiple-output (MIMO) radio-access technology, there is a high challenge to evaluate car antennas appropriately, taking into account the antenna environment formed by the car body in the MIMO channel. New statistical methods are required on base of the propagation properties of antennas which are integrated close to each other in a reflecting and refracting environment. In this contribution we present an evaluation method of LTE-car antennas, which enables the analysis of virtual drives. The test drives are performed via simulation of driving paths in urban or rural environments with ray-tracing, while the description of the receiving part is given via the complete information of the complex antenna characteristics of the coupled antennas which are measured on a real car. An example with two realized antenna modules is analyzed by this method and the results are compared to results from real drives.

CONVENED SESSION PAPERS In this paper, two-dimensional unitary matrix pencil (2-D UMP) is utilized for the synthesis of sparse planar arrays. Firstly, the estimation of synthesis parameters is recast as a 2-D poles extraction problem. By virtue of the equivalent matrix pencil obtained with a unitary transformation, 2-D positions including horizontal and vertical coordinates are directly found as the generalized eigenvalues of the real matrix pencils without solving poles. Owing to the utilization of a unitary transformation, the computational complexity can be significantly reduced since only the real computations are involved in the singular value decomposition (SVD) and eigenvalue decomposition (EVD) procedures. Consequently, the element excitations can be estimated once the real element positions are obtained by the correct pairing. A representative numerical experiment is provided to assess the effectiveness and advantages of the proposed method. Haiou Shen 1448868 Air Force Engineering University P.R.

A configuration based on a multi-source feeding scheme is also tailored by a superposition of modulation patterns. Numerical results based on the Method of Moments are presented for validation.

The approach represents a powerful extension of a design procedure available for the one-dimensional case and able to outperform most of previous synthesis techniques. By exploiting at best the multiplicity of equivalent solutions available for the generation of an unique shaped-beam power pattern, the theory of Compressive Sensing, and a smart formulation in terms of a Convex Programming problem, the proposed design technique results extremely fast and effective.

REGULAR SESSION PAPERS Complex operating environment could introduce serious degradation to the electromagnetic property of active phased array antenna. The effective compensation techniques become the key for antenna to perform in reliable service condition. Therefore, a method combined coupled structural-electromagnetic modal with two-dimensional fast Fourier transform for compensation is presented. A calculation modal of the excitation current compensation for planar array is established accordingly. The adjustment quantities of excitation amplitude and phase can be quickly obtained corresponding to the position error of the element, which could be implemented to recover a high quality pattern from a distorted antenna. Lastly, an X-band space-based active phased array antenna is illustrated to compensate its property under the impact of both space environment and heat power from the electric devices.

CONVENED SESSION PAPERS In the last twenty years, Microwave Imaging (MWI) has emerged as one of the most promising novel medical imaging modalities. With European researchers being at the forefront of MWI development of medical applications, the creation in 2013 of the Action network "MiMed" (MIcrowave MEDical) in the framework of the European COoperation in Science and Technology (COST) was welcomed with vivid enthusiasm. MiMed has polarised mostly independent research efforts into the design of several MWI devices. Such a reserve of knowledge and numerous initiatives carried by MiMed have constituted a unique opportunity for researchers to leverage existing experience and expertise to streamline the transition from simulation/phantom testing to full clinical trials and clinical adoption of MWI devices. Moreover, collaboration among participants has provided the support to overcome common challenges and bring MWI from "research bench to patient bedside", boosting the European Research Area and its excellence in a worldwide context.

CONVENED SESSION PAPERS Carbon-rubber phantoms have recently been introduced as tissue-mimicking materials for microwave biomedical applications. In contrast to other phantom materials, carbon-rubber materials allow easy construction of heterogeneous phantoms with time-stable dielectric properties. However, the fabrication of large solid phantoms may pose a challenge. This paper investigates a large dielectric carbon-rubber phantom with four inclusions with an average dielectric contrast of only 10%.

CONVENED SESSION PAPERS We consider the utilization of higher-order basis functions, in the sparse processing framework, for brain stroke monitoring. Instead of retrieving the permittivity of the whole brain, the goal is estimate the variation of the electromagnetic parameters of the brain between two measurements. We assume that the differences in the measured electromagnetic field indicate the stroke evolution. Using average head model and different noise levels, we show that the method yields accurate results even for low signal-to-noise ratios (SNR) and limited prior knowledge of the brain tissue parameters Marija Nikolic 235005 University of Belgrade Serbia 1 Rosa Scapaticci 688911 CNR-National Research Council of Italy Italy 0 Lorenzo Crocco 369189 CNR - National Research Council of Italy Italy 0 11:00 11:20 1570314101 CS16 Mic Medical Tech.8 Microwave Vision: From RF Safety to Medical Imaging 2.

CONVENED SESSION PAPERS This paper presents a novel approach to microwave hyperthermia exploiting magnetic nanoparticles as focusing agents, and reports the results of a 2D numerical study aimed at preliminarily assessing its effectiveness. The approach exploits magnetic nanoparticles, locally supplied to the tumor, to induce, through an external polarizing magnetic field, a detectable variation of its magnetic contrast. This variation is exploited to determine the excitations of the antenna array focusing the electromagnetic energy on the tumor. The advantage is that the synthesis of the excitations does not require any information neither on the geometry nor on the electromagnetic properties of the treated region, thus achieving totally blind field focusing. The magnetic nature of the magnetic nanoparticles contrast has required the development of an ad-hoc synthesis strategy, which, together with the use of magnetic nanoparticles, represents the novelty of the approach.

CONVENED SESSION PAPERS Magnetic modulated nanoparticles are a promising approach to enhance microwave breast cancer detection and imaging. Assuming that functionalized magnetic nanoparticles are able to accumulate selectively within tumorous tissue, this approach can increase the diagnostic reliability. This contribution deals with detecting and imaging of magnetic nanoparticles by means of ultra wideband sensing. Magnetic nanoparticles are modulated by means of an external magnetic field and the resulting scattering changes of the magnetic nanoparticles are measured using M-sequence radar technology. Investigations are based on phantom measurements and the detection of the response caused by magnetic nanoparticles is realized by a differential measurement between ON- and OFF-state of the polarizing magnetic field. Results show a detectability of magnetic nanoparticles in a realistic measurement scenario. Based on this, 3D images for different amounts of magnetic nanoparticles are realized using a delay-and-sum beamforming algorithm.

CONVENED SESSION PAPERS With growing demand for mm-Wave applications, gap waveguide technology introduced many advantageous features compared to hollow waveguides or SIW. Till now several wideband, high-efficiency and highly directive planar gap waveguide antennas have been proposed. Recently, a new form of pins, the so called half-height pin, is proposed for realizing gap waveguide technology. In this paper, a wide-band, high gain, and high efficiency 8x8-element slot array antenna for 60 GHz band based on the new form of pins is introduced. The simulation shows a very good performance of the antenna, with 14% bandwidth of the 10 dB return loss, 26 dBi realized gain and close to 80% aperture efficiency. The antenna has less difficulty in manufacturing because of new pin form and therefore is suitable for the low cost mass production of mm-Wave antennas.

CONVENED SESSION PAPERS A compact 32-slot continuous transverse stub (CTS) antenna array operating at E-band is proposed here. It is excited by a hollow parallel plate waveguide (PPW) corporate feed network to insure a broad band operation. A parabolic pillbox coupler is used to create the requested current line exciting for the PPW beamformer. The pillbox coupler is fed by a substrate integrated waveguide (SIW) horn located in the focal plane of the parabola. The most important features of the antenna building blocks are described in detail, and the numerical results demonstrate the excellent performance of the proposed antenna. A reflection coefficient lower than -19 dB and a gain larger than 31 dBi are obtained over a 19% fractional bandwidth spanning between 71 and 86 GHz. The proposed antenna architecture is an innovative solution for E-band backhauling applications for next generation 5G networks.

CONVENED SESSION PAPERS In this work, the concept of dielectric-filled waveguide antenna array operating at 71-76 GHz is studied. The developed prototype consists of air-filled to dielectric-filled waveguide transition, dielectric filled power divider, and four dielectric radiating elements. The idea behind using dielectric-filled components is to minimize feeding waveguide structure dimensions in order to have spacing of half a wavelength between the radiating elements. This can help to reduce the grating lobes and it can be possible to integrate phase shifters since there is enough space between the elements. Such antenna structure is a light-weight and low cost in manufacturing. The simulation results show that such antenna array has 11.4 dBi gain with 23.6 half power beamwidth.

CONVENED SESSION PAPERS In this paper different possibilities for an in-antenna power-combining approach are investigated. The radiation is based on the principle of an integrated lens antenna (ILA), where the primary radiator consists of a slot antenna with two or more excitation elements. The output power of parallel amplifiers can be directly combined in the primary radiator itself without any additional combiner network. Regarding the antenna efficiency, the practical limit for the number of parallel branches is found out by simulations. Additionally, different power-splitter networks for achieving a linearly or circularly polarized radiation are presented and it is shown how the input impedance of the excitation elements changes with different number of feed-lines. Finally, primary radiators with different input impedances and polarization schemes are presented and verified by calibrated gain measurements in D-band and H-band frequencies.

CONVENED SESSION PAPERS For the implementation of high-gain dual-band transmit-arrays, adequate unit-cells have to be designed. The potential difficulty is related to the independent 360º phase wrapping needed at each band to compensate arbitrarily large equivalent path length phase compensation. This points to an intractable number of phase combinations at each band, leading to a possibly very large number of different unit-cells. A generic formulation is presented for the design of dual-band unit-cells that considerably reduces the search space leading to thinner and lighter configurations. An example, is presented for Ka-band with a configuration of dual-band unit-cells working simultaneously at 20 and 30 GHz. The unit-cells ensuring both the required phase values and a transmission coefficient amplitude better than -0.9 dB in both bands.

CONVENED SESSION PAPERS The paper presents a novel concept of the integrated lens antenna (ILA) that includes multiple feeds and provides continuous scanning without gain degradation in the given scanning sector. Each feed includes its own RF mixing stage and a radiating element mounted on the lens back focal surface. Continuous scanning is achieved by the power distribution over all the radiating elements that leads to a predictable displacement of the common phase center of the group of active elements relatively to the lens axis. The lens focuses the radiation in the particular direction defined by this phase center position. Low losses and continuous scanning range make this ILA concept perspective for practical implementation in different millimeter-wave applications like point-to-point radios and future 5G systems.

CONVENED SESSION PAPERS Although the classical Theory of Characteristic Modes allows an arbitrary structure to be analyzed prior to the implementation of physical feeds, structures containing dielectrics have so far received very little attention. Recently, a mesh perturbation method is proposed to remove internal resonances from the characteristic mode (CM) solution for lossy dielectrics obtained using the computationally efficient surface integral equation. Herein this method was applied to extract the CMs of a lossy structure consisting of a terminal chassis held in a user hand. These modes were then individually analyzed and a subset was chosen to design a MIMO antenna with not only very low correlation, but also low hand-induced losses.

CONVENED SESSION PAPERS In this paper, a frequency reconfigurable multiple-input-multiple-output (MIMO) slot antenna is presented. The proposed design is low profile and compact with wide tunability range, covering several well-known frequency bands from 1800 MHz to 2450 MHz. The frequency reconfigurability is achieved by loading the annular slot with varactor diodes. The antenna system is also analyzed for MIMO performance metrics. Moreover, the effect of circular slot antenna on the chassis modes is also investigated using the theory of characteristic modes (TCM). The physical principle behind frequency reconfigurability is also investigated using TCM analysis. An interesting finding is observed using varactor diodes for frequency reconfigurability, that is the reactive impedance loading does not alter the modal significance (MS) plots but only aid in the input impedance matching at different frequency bands.

CONVENED SESSION PAPERS A small UWB circular monopole antenna with a differential feed is presented in this paper, as a solution to increase the stability of the radiation pattern of a single-fed circular monopole antenna. A detailed characteristic modes analysis is presented in order to support the selection of the feeding mechanism. Simulated active-S parameter is shown for the proposed antenna, showing a good matching for the UWB frequency range. Normalized surface current distributions are presented, and 3D radiation patterns are compared to a reference monopole. The antenna structure shows more stable and omnidirectional radiation patterns over the studied frequency range compared to a same sized single-fed reference monopole.

CONVENED SESSION PAPERS In this paper, a modal analysis of a slot inserted in a finite ground plane is presented, giving physical understanding of its radiation behavior and the interaction effects between the slot and the plane. The Theory of Characteristic Modes (TCM) reveals that for the case of slotted planar antennas the modes of the slot do not appear as independent modes. This paper also shows that the slot resonance fixes the upper frequency of the excited modes in the combined structure formed by the slot and the finite plate. Moreover, the modal analysis demonstrates that the radiation pattern stability and the radiation bandwidth of the slot antenna are directly related with the size of the finite ground plane. The conclusions reached with the application of TCM can be employed to optimize the geometry and the size of the finite plate in order to prevent the excitation of non-desired modes.

CONVENED SESSION PAPERS The limited eigenvalue dynamic range calculated from a characteristic mode solution is studied. Two methods of handling singular terms in the electric field integral equation matrix filling process are reviewed. Characteristic mode solutions using each singular treatment are compared with modal solutions obtained from a commercial solver. Results show that small alterations to the handling of singular terms in the matrix fill stage can lead to large gains in spectral depth. These gains outpace improvements obtained by increasing total mesh density.

CONVENED SESSION PAPERS Metamaterial inspired concept is a very promising technique to miniaturise antennas suffering from their small electrical sizes while keeping a good radiation efficiency. In this paper, the theory of characteristic modes is used to perform a study of the powers and Q factors of metamaterial inspired antennas, such as the common 2D electric based monopole antenna with a meander line [1]. The aim of this work is to initiate to a new methodology to be used by antenna designers to address the problem of associating metamaterial inclusions to electrically small antennas in order to enhance their performances. It will be able to find the adequate inclusion in order to match an arbitrary shaped antenna in its electrically small regime and keep high overall efficiency. This will require the solving of the eigenvalue problem with further post-processing of the quantities provided by the theory of characteristic modes. M.

REGULAR SESSION PAPERS The potential ways how to excite optimal currents are discussed in this paper. It is be shown that realistic feeding is not compatible with optimal current distributions and therefore proper shape modifications are needed, changing thus, however, the original optimal currents. A set of deterministic algorithms to synthesize feeding network or the radiators geometry will be summarized, and novel procedure to get suboptimal shapes will be presented. Results will be compared with state-of-the-art multi-objective algorithm.

CONVENED SESSION PAPERS Fundamental modernization of railway transportation is on the agenda of the Next Generation Train (NGT) project funded by the German Aerospace Center DLR and the Roll2Rail project within the Shift2Rail initiative. Reliable direct Train to Train (T2T) communication can significantly enhance train control and signaling towards semi or fully autonomous operation, in order to significantly increase the efficiency and safety. With Terrestrial Trunked Radio (TETRA) a communication standard is available with high potential for this use-case. It offers the ability of direct communications between vehicles, i.e. ad-hoc communications over several kilometers. In this paper, we summarize the results of T2T measurements conducted at 450 MHz. We will characterize the propagation conditions and assess the link performance by analyzing transmissions in different scenarios and railway environments.

CONVENED SESSION PAPERS To meet the rapid increasing demand of the high data rate communication, millimeter wave communication system has attracted considerable attention. In this paper, a millimeter wave wideband channel measurement with mobility in urban micro-cell mobile communication scenario at 28 GHz is presented for the purpose of capturing the channel characteristics. Based on the measured data, we analyze the path number, root mean square delay spread (rms DS) and mean excess delay. It is found that the distribution of the path number is well fitted by a Normal distribution while the distribution of the rms DS and mean excess delay is fitted well by a Lognormal distribution. The statistics of these parameters are also given and are compared with the results in other measurements. Besides, the effects of the distance on the path number are discussed. These analysis results can give insight into the design of the 5G wireless communication system. Pan Tang 1335125 Beijing University of Posts and Telecommunications P.R.

CONVENED SESSION PAPERS Within the next decades the railways will change to fully autonomous high speed trains. An increase in efficiency and safety and cost reductions would go hand in hand. Today's centralized railway management system and established regulations can not cope with trains driving within the absolute braking distance as it would be necessary for electronic coupling or platooning maneuvers. Hence, to ensure safety and reliability, new applications and changes in the train-control and -management are necessary. Such changes demand new reliable communication links between train-to-train (T2T) and future developments on train-to-ground (T2G). T2G will be covered by LTE-R which shall replace today's GSM-R. The decentralized T2T communication is hardly investigated and no technology has been selected. This publication focuses on the wide band propagation for T2T and describes a extensive channel sounding measurement campaign with two HSTs. First results of T2T communication at high speed conditions in different environments are presented.

Measurements have been made on a real environment using test transmitters at 900, 2400 and 5700 Mhz, and making measurements inside a HST with external and internal antennas and a portable receiver. The results have shown a high shieling effect of the train at all frequencies and in both cases towers. With high towers the shieling effect of the train is 24dB and from the station platform is 17db. Higher frequencies have shown better behavior .

CONVENED SESSION PAPERS In the context of a growing interest in the use of millimetre wave frequencies for railway applications, we propose to analyse the influence of this environment on antenna performances. The railway environment being quite harsh with the presence of lossy and conductive particles and elements, near-field effects can be detrimental to the efficiency of wireless links at these frequencies. This paper focuses on two specific conditions namely the presence of a layer of metallic dust and a thin water film on radiating elements. It is shown that the impact of these two parameters cannot be considered negligible. In an operational scenario, the antenna main lobe may be tilted backwards. For point-to-point communication systems, trackside antennas will be coated with a deposit of metallic dust. The deterioration of the radiation pattern and the reflection coefficient should be taken into account when forecasting radio propagation, establishing budget links and evaluating performance indicators.

CONVENED SESSION PAPERS In this paper, the impact of truck convoys on radio wave propagation at the mm-wave frequency band in a two lane road tunnel is analyses by computer simulations. The analyzes reveal that the propagation of radio waves is not affected outside the convoy if a convoy occupies only one lane, while two convoys in both lanes cause serious drop of signal level behind the convoys. The signal level is decreased and delay spread is increased within the convoy, which suggests the usage of the vehicle to vehicle communication within a convoy. In addition, due to misalignment of transmitting and receive directional antennas a significant signal gap is occurred close to the base station. We suggest the usage of two antennas at the base station, one omnidirectional to cover proximity areas and the second one directional to cover distance areas along the tunnel.

REGULAR SESSION PAPERS The usage of driving assistance systems that are based on V2X communication technologies as ITS-G5 are a promising technology to increase road safety as well as traffic efficiency. To allow for communication even in challenging propagation scenarios (such as busy urban intersection), we investigated a new concept for rooftop mounted beam-steerable vehicular antennas which is a 2-element monopole array (parallel and orthogonal to direction of travel) and a switchless reconfigurable antenna. It shows that the monopole array configurations give the best propagation results in any scenario and time step. However, the beams have to be steered dynamically to ensure the best possible communication.

CONVENED SESSION PAPERS This paper summarizes the latest advances on an innovative, broadband multibeam antenna, proposed for satellite communications by the Institute of Electronics and Telecommunications of Rennes (IETR), in the framework of a collaborative research with the French Space Agency (Centre National d'Etudes Spatiales). The antenna comprises an array of long slots, parallel-fed by a corporate feed network of parallel plate waveguides. An integrated quasi-optical beamformer, illuminated by a single horn or by a focal array of horns, excites the feed network. The beam scanning can be achieved both mechanically and electronically. The numerical models developed for the analysis and design are reviewed. The experimental results presented for a Ka-band design demonstrates the wideband, wide-angle scanning performance of the proposed architecture. Finally, future research lines for achieving circular polarization are projected. The proposed antenna concept is particularly suitable for high throughput ground terminals on moving platforms.

CONVENED SESSION PAPERS Being developed in partnership between NASA and the Indian Space Research Organisation (ISRO), the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite is planned to launch in late 2020. NISAR will measure many aspects of how Earth is changing with unprecedented accuracy on a global scale from a Low Earth Orbit (LEO) platform. With a 12m deployable mesh reflector, NISAR will feature one of the largest deployable mesh reflector ever launched for a scientific mission. Two large planar phased arrays will feed the reflector, one that will operate at L-Band and be developed by the Jet Propulsion Laboratory (JPL), and an S-band array that will be developed at the ISRO Space Application Centre (SAC). This paper describes the preliminary design of the L-Band feed array.

CONVENED SESSION PAPERS A novel multiple beam antenna architecture is proposed based on a quasi-optical lens beamformer. It consists in the combination of a doubly curved reflector with a stack of fully metallic parallel plate waveguide beamformers terminated with a flare. It has the capability to reduce the phase aberration over a large angular sector, and thus to improve the characteristics of radiated multiple beams. A novel quasi-optical beamformer based on a continuous delay lens was designed, manufactured and tested. The wide band and wide scanning capability is demonstrated at Ku band. Low return loss and mutual coupling is also achieved for all input ports. The agreement between measurements and simulations is outstanding, for both the S parameters and the radiation patterns. The beamformer was also designed to operate in the Ka- Rx/Tx band. It is of high interest for on-board antennas for LEO and MEO constellation systems.

CONVENED SESSION PAPERS In this work we present an antenna concept for wideband and wide-scanning phased array applications. The array unit cell consists of a connected-slot element radiating in the presence of a backing reflector and an artificial dielectric superstrate. The artificial dielectrics have anisotropic characteristics that allows to avoid surface waves and scan blindness over a wide scan range and a large frequency band. The design of a dual-polarized array operating in the bandwidth from 7 to 14.5 GHz is presented. Simulated performance show active voltage standing wave ratio (VSWR) lower than 2.5 for scanning up to 60 degrees in the H-plane and 70 degrees in the E-plane. This array is implemented with a single multi-layer printed circuit board, which represents an advantage in terms of cost and complexity, compared to previous connected-array designs.

CONVENED SESSION PAPERS Communications with satellites in deep space require large antenna aperture systems on the ground in order to receive and transmit data at the power levels necessary to establish a link. However, these large antennas are costly to build and maintain and represent single point failure systems. An alternative to this approach, presently being investigated by NASA, is the use of several smaller aperture antennas combined in an array. The additional difficulty introduced by this approach is the more pronounced impact of atmospheric turbulence which induce phase scintillation errors across the effective aperture of the array. In this paper, the impact of atmospheric-induced phase scintillation on ground based antenna arrays is defined and techniques to mitigate phase scintillation for next generation communications arrays are introduced. A particular focus is made on a novel passive phase scintillation sensing technique utilizing a blind source separation (BSS) approach.

CONVENED SESSION PAPERS In this work we present an approach for the prediction of far-field pattern characteristics of phased array fed reflector antennas by modeling only a small part of the array. In this approach, the simulated EEPs of the FPA are modeled as the phase-shifted versions of the simulated embedded element pattern (EEP) of the central element, and thereafter combined with the optimum weighting coefficients in order to find the total pattern of the feed. Although, the EEPs of dense array antennas are generally not identical (due to the array antenna mutual coupling and edge truncation effects), for typical FPA excitation scenarios, where the array edge elements have relatively low weights to produce the desired illumination of the reflector, this simplified approach has been found sufficiently accurate.

CONVENED SESSION PAPERS Space telecommunication antenna applications with required in-orbit shape variation ask for morphing skins of antenna reflectors for fulfilment of diverse requirements. Mechanically reconfigurable reflectors can replace the typical configuration of several shaped reflectors and satellites with a single reflector and, thereby, enhance coverage performance to several needed areas of the Earth during a single lifetime in orbit. Thus, their application promises huge cost savings. Design manufacturing and verification of the reflector morphing skin is a challenging task because besides the ability to morph they have to satisfy mechanical and radio frequency stringent requirements. Most challenging mechanical requirement is an amplitude of reshaping in the range of +/- 15 mm maintaining the smoothness of the surface. Material selection and design, tailoring of its properties based on numerical and experimental studies, enhancing radio frequency characteristics and resulting verification of a potential concept of the mechanically reconfigurable reflector are addressed in the paper.

CONVENED SESSION PAPERS An hybrid array fed reflector antenna solution is described in this paper, combining a focused geometry in one plane and an imaging (defocused) geometry in the orthogonal plane. This doubly curved reflector geometry can be combined with a stack of linear phased arrays, introducing some re-configurability at a moderate cost when compared to more conventional imaging reflector solutions using planar phased arrays. A simple analytical formulation is derived to define the proposed doubly curved surface and numerical results are presented for a multiple beam mission at Ka-band.

CONVENED SESSION PAPERS The efficiency of use of the parabolic reflector of a single offset reflector compact antenna test range (CATR) is affected largely by the illumination provided by the range feed and the reflector edge treatment with the realized quiet zone (QZ) diameter being typically as little as 30% of the diameter of the reflector. Different reflector edge treatments are commonly employed to taper the intensity of the reflected fields at the reflector aperture boundary. Such strategies mean that at higher frequencies the transverse dimensions of the QZ are unnecessarily reduced thereby decreasing the spatial efficiency of the CATR. In this paper we report preliminary results that investigate an alternative strategy that utilised a shaped beam antenna whose excitation is optimized to achieve maximum QZ size. We demonstrate that a 9-element array feeding an un-serrated rim reflector can attain a useable QZ size approaching 50% the size of the diameter main reflector.

CONVENED SESSION PAPERS Large compensated compact ranges are designed for antenna and payload testing of spacecraft antennas and payload units. The Compensated Compact Range concept (CCR) of Airbus does have two major advantages for such measurements. First of all a small cross-polarization (< -40 dB) for frequencies ≥ 3 GHz due to the compensating reflector design. In addition they provide a scanning capability of the test zone. The first item is a necessary condition for precise spacecraft antenna measurements at which the cross-polar performance is an important requirement. The second one, the scanning capability, is an interesting feature for deployed antennas of large spacecraft's. It can be easily utilized for antenna testing as well as radiated payload testing scenarios. This paper addresses practical implementations, achieved performance figures of the latest installations and inherent limitations by the utilization of the scanned quiet zones at a CCR test facility.

CONVENED SESSION PAPERS The spherical near-field antenna measurement technique is unique in combining several distinct advantages and it generally constitutes the most accurate technique for experimental characterization of radiation from antennas. From the conception in 1970, spherical near-field antenna measurements have matured into a well-established technique that is widely used for many wireless applications. For several of these applications, other measurements techniques would do equally well. However, for high-accuracy applications, such as remote sensing satellite missions in ESA's Earth Observation Programme with uncertainty requirments for directivity being at the level of 0.05dB, the spherical near-field antenna measurement technique is clearly advantageous. This paper addresses several aspects of high-accuracy antenna testing using the spherical near-field antenna measurement technique. This involves sources of uncertainty, measurement procedures, processing procedures, and facility validation - as well as examples of measurement campaigns with challenging uncertainty requirements for directivity and gain Olav Breinbjerg 454793 Technical University of Denmark Denmark 1 10:00 10:20 1570317493 CS42 Sat Measure.5 On Orbit Performance Validation & Verification of the SMAP Instrument Antenna 2. CONVENED SESSION PAPERS NASA's Soil Moisture Active Passive (SMAP) Mission is currently flying in a 685 km orbit. Featuring a Synthetic Aperture Radar (SAR) and a radiometer sharing the same antenna, SMAP was developed in collaboration between Jet Propulsion Laboratory (JPL) and Goddard Space Flight Center (GSFC). While the radar requirements on the instrument antenna were more benign from an RF point of view, the radiometer requirement were more difficult to meet because of the stability required by the radiometer to operate to its full potential. The instrument antenna performance was predicted by a very detailed RF model and verified by measuring a 1/10th scale model with great accuracy before launch. Once in orbit, we had the opportunity to measure the antenna performance for both the radiometer and the radar and compare it with the predicted performance given by our RF model.

In this paper, we present an overview of the COWVR instrument, and a detailed description of the EM modeling of the antenna system and the test campaign carried out at JPL to assess its performance. Special emphasis has been placed on assessing the accuracy of the predictions made with the RF model. We will show that the predicted radiation patterns are accurate enough so one can use them for orbit radiometer calibration.

CONVENED SESSION PAPERS In this contribution, a calibration method for broadband off-axis holography is presented. The phase of the reference antenna is retrieved in an intermediate step by using an auxiliary well known antenna, whose phase can be theoretically modeled. Therefore, the vector calibration can be bypassed yielding a process based on scalar measurements only. The proposed method can be applied to near- and far-field acquisitions and has been validated by means of a numerical example for the characterization of a parabolic reflector in the W-band.

REGULAR SESSION PAPERS Recent use of measured data as near field sources in Computational Electro Magnetic (CEM) tools has opened the possibility to represent antennas in numerical simulations, even when the antenna characteristics and geometry are unknown and therefore cannot be included in a full wave model [1-4]. The near field source consists of an equivalent current representation of the antenna, which is prepared by the inverse source method from the measured radiation pattern [5-9]. This link bringing together numerical simulations and antenna measurements has been validated by a proper campaign, that involves MVG and different software (SW) vendors [10-15]. In the first part of this paper, the latest results of the validation are presented completing the activities described in [1-3]. In the second part of the paper, the link between measurements and simulations has been applied to more complex and/or realistic problems, including scattering problems.

REGULAR SESSION PAPERS In this paper, the generation of passive intermodulation at standard TNC coaxial connectors is investigated. A series of tests has been performed in order to analysis the intermodulation level under different temperature circumstances. The relationship between the intermodulation response of the connectors and the change of temperature and straining on the junctions has been studied. It has been found that the passive intermodulation of TNC coaxial connectors was very sensitive to the changes of temperature and straining. High intermodulation should be caused when warming up from the low temperature. Rui Wang 1351155 National Key Laboratory of Science and Technology on Space Microwave P.R.

REGULAR SESSION PAPERS This paper proposes a method of constructing an antenna array on the typical ground plane of the modern mobile terminal. An IFA and a slot in a metal frame antenna elements have been used to illustrate the proposed method. The radiation pattern of the element is recorded at the chosen number of the discrete locations on the ground plane. Antenna elements at the positions, where the boresight is similar and the maximum gain is high are combined into an array. The performance is verified by comparing performance of the one antenna element to the performance of the constructed arrays. The proposed method works both in free space and in data mode for two types of antenna elements. The method shown that a maximum gain of the constructed array is 1 to 2.5 dB higher then the gain of a single element both in free space and in data mode.

REGULAR SESSION PAPERS Pre-fractal wire antennas show a decreasing resonant frequency for increasing iteration number due to the longer wire length. However, the resonant frequency reduction stagnates after a few iterations. This paper gives an explanation for this behavior, that we call the shortcut effect, based on the signal taking shortcuts between wire corners. This hypothesis is verified by computer simulation in the time domain and it is shown that it is almost not present in the plasmonic regime at optical frequencies: the high-localization of plasmonic modes mitigates the shortcut signal, so that plasmonic antennas show a much better reduction of the resonant frequency for a higher fractal iteration count that the microwave frequency ones.

The proposed structure is expected to make good enhancement of light absorption inside the active layer of the photovoltaics (PV) in the visible and near infrared range of frequencies (200-900 THz). In this work, the proposed Nano-antenna is in a shape of crescent with a gap on its side, that is embedded inside the photovoltaic cell resulting in a highly confined near-field around the nanoparticle and with the semiconductor forming the PV. The extinction cross-section of the proposed nanoparticle in vacuum has been calculated versus the wavelength. And, the modes of the fields are studied. The effect of embedding this crescent nanoparticle in a silicon photovoltaic is investigated by comparing its absorption with the conventional disk nanoparticle. The proposed structure enhances the light absorption improving the efficiency of the PV.

REGULAR SESSION PAPERS This contribution discusses a near-field antenna setup capable of delivering multiple input signals with a controllable (i.e., user defined) amplitude and phase relations to an antenna under test, operating in the X-band. The setup is based on a Cartesian modulation (phase and quadrature signals) of phase coherent signals, achieved employing broadband passive IQ-mixers controlled via high-resolution digital-to-analogue converters (DACs). A dedicated calibration procedure allows achieving independent phase and amplitude control on the different signal paths to compensate for loss and delay mismatches among the different channels. The capability to align the relative phases of the various path with respect to one enables the direct testing of phased antenna arrays. The system calibration is elaborately described. The proposed Cartesian modulation is demonstrated by studying a complex antenna array, with a subset of its elements being controlled independently and phase delayed for actively controlling the far-field radiation pattern.

REGULAR SESSION PAPERS In spherical Near Field (NF) measurements post-processing techniques based on spatial filtering have been presented as promising tools for the mitigation of echoes or stray signals deriving from the surrounding environment. The spatial filtering is very efficient in measurement scenarios with a stationary Antenna Under Test (AUT). Whenever the AUT is rotating, in order to increase the effectiveness of the echo reduction, the antenna needs to be displaced outside the center of rotation. Unfortunately, the measurement of the AUT in an offset configuration requires the acquisition of a number of samples higher respect to the onset configuration. An innovative spherical NF/FF transformation algorithm for offset measurements based on a Translated Spherical Wave Expansion (TSWE) has been recently proposed. In this paper, we investigate by experiment the echo reduction properties of offset AUT measurements using TSWE.

REGULAR SESSION PAPERS The paper proposes a fast and interpolation-free method for near-field 3-D radar imaging. The scattered data are measured on 2-D planar antenna array with wideband stepped frequency signal. The near-field 3-D imaging procedure is indeed a nonuniform summation problem. Different from the conventional interpolation fast Fourier transform (FFT) method, the proposed method regards the imaging procedure as a Fourier basis mismatch issue and utilizes perturbation technology to solve the problem. The nonuniform wavenumber grid is first approximated onto a newly reconstructed uniform grid by first-order Taylor expansion. Then the nonuniform spatial spectrum summation procedure can be efficiently implemented by two 3-D inverse FFTs to obtain 3-D image. Experiment demonstrates the effectiveness and efficiency of the proposed method. Yingzhi Kan 1448429 National University of Defense Technology P.R.

REGULAR SESSION PAPERS It has become a popular trend in using metallic housing for mobile phone. The metallic housing often posts a great challenge towards the design of internal antenna which is used commonly in mobile devices. As such, it has become a common practice that most will integrate the metallic housing as part of the antenna for the mobile phone. This paper presents an antenna solution for mobile phone with a metallic back cover. The antenna solution is for the Main Antenna operating at several frequency bands in the range of 700 - 960MHz, 1710 - 2170MHz, 2300 - 2400MHz as well as 2500 - 2690MHz, in the cellular network. The antenna solution presented in this paper, demonstrates the use of tunable component, integrating with the metallic housing to provide flexible tuning to cover the various frequency spectrums in the 2G, 3G and 4G cellular network.

REGULAR SESSION PAPERS In this work, we present a new formula for evaluating the half-power beamwidth (HPBW) of 1-D leaky-wave antennas (1-D LWAs). With respect to Oliner's formula, whose validity is restricted to certain hypothesis on the beam size and the pointing angle, our analysis is quite general, being accurate even when radiation points near endfire, where current formulas notably diverge. Even more interestingly, this new expression takes into account the dependence of the HPBW on different parameters, namely the length of the antenna, the pointing angle, and the attenuation constant. A simple approximate analytical formula is derived and validated through numerical results. To complete the picture, previous Oliner's formula is obtained as a limiting case of this general formulation. These results would provide a very useful tool for the correct prediction of the radiating features of 1-D LWAs. Walter Fuscaldo 982785 Sapienza University of Rome Italy 1 David R.

REGULAR SESSION PAPERS In this paper, the directivity limit of end-fire arrays based on Huygens source elements has been numerically investigated. Firstly, the elementary infinitesimal Huygens source behavior is introduced and studied through Spherical Wave Expansion (SWE). Then, the maximum theoretical directivity of two-, three- and four-element arrays is calculated as a function of the inter-elements spacing. The optimization has been performed using a synthesis method based on SWE. For an inter-element spacing of a tenth of the wavelength, the obtained directivities are equal to 9.0 dBi, 11.7 dBi and 13.7 dBi for the two-, three- and four-element arrays, respectively.

REGULAR SESSION PAPERS Most antenna theories treat an antenna is reciprocal, though non-reciprocal passive antennas are possible with gyrators and circulators. We describe basic properties of transmitting and receiving antennas which can be non-reciprocal, then related them considering thermodynamic equilibrium. An extension of the fundamental equation is derived, which is valid for any passive antennas. Based on the extended fundamental equation, we propose to define a new property of receiving antenna, reception efficiency. The reception efficiency is equal to the radiation efficiency for reciprocal antennas. The properties of a non-reciprocal passive antenna can be organized with the receiving efficiency, making transmission and reception pairs. Further, we introduce reciprocity conjugate and construct a non-reciprocal antenna model with two reciprocal antennas.

CMA of aperture antennas is usually based on the equivalent magnetic current method but the solver is not available from main-stream solvers. In this paper, the problem is studied for the first time through the duality principle. Eigenvalues, magnetic current distribution of arbitrary aperture antennas can be obtained by the CMA of its complementary form. Formulation of the method is given and the relationship between aperture and its complementary form is verified by numerical examples. Peiyu Liang 1365177 Beihang University P.R.

REGULAR SESSION PAPERS Historically, antenna designs have been dictated by specific performance requirements for gain, beamwidth, return loss, etc. without consideration of the environment the antenna is being deployed in. Herein, we consider an over-the-air (OTA) approach for characterizing antenna performance for a wireless device arbitrarily deployed in a cluttered environment, e.g., a machine-to-machine (M2M) installation. We then explore antenna system geometries that can be cofabricated with the device's enclosure using 3D printing technologies. Based on a channel characterization study and fabrication constraints, we propose a tripolar antenna design that is readily integrated with, for example, a wireless sensor.

REGULAR SESSION PAPERS The automotive industry is in need of reliable, accurate yet cost-effective over-the-air (OTA) characterization methods of the communications systems installed on cars. This paper analyses the scattering contributions to spurious variations of receive signals in a Random Line-of-Sight (Random-LOS) measurement setup in a semi-anechoic chamber. Figures of merit are the delay spread and the dynamic variations of the receive signals. Transmission measurements were performed on a two-element LTE shark-fin antenna mounted on the roof of a Volvo XC90. We show that by using a vertically oriented uniform linear array, with vertically polarized bowtie antenna elements, we can efficiently remove the unwanted ground reflection present when a single bowtie antenna is used. We also show that the improvement depends on the position of the antennas mounted on the car as well as on the azimuthal angle.

REGULAR SESSION PAPERS Antenna characterization is usually performed by antenna pattern measurements in an anechoic chamber. Subsequently, a conducted test, the Radiated Two-Stage (RTS) or the Wireless-Cable method can be used for an overall system test considering the measured patterns. In this paper we present a method to perform device tests for antenna arrays / smart antennas without the need of radiation pattern measurements, and we validate it experimentally. By using Over-The-Air tests in a Virtual Electromagnetic Environment and Wave-Field Synthesis, the propagation environment can be realistically recreated in the region around a Device-Under-Test. This allows for reproducible performance comparisons of different antennas or systems under identical propagation environment conditions. As a special application, we consider the Controlled Reception Pattern Antenna (CRPA) in a Global Navigation Satellite Systems environment in the presence of interferer signals.

REGULAR SESSION PAPERS The wireless industry is getting deeply engaged in the 5th generation communication standard. Despite lack of clear definitions, there are some parameters of the emerging standard which are commonly accepted. Higher frequencies (frequencies above 6 GHz) in the millimeter wave spectrum will be a key component for enabling a massive increase of the available bandwidth and thus data rates for the end users. This will however impose challenges on the test equipment for the wireless devices operating on these frequencies. The Over-the-Air test facilities used today for 4G and legacy standards are optimized for operation below 6 GHz. A frequently used tool for Over-the-Air performance assessment is the reverberation chamber. This paper will analyze the feasibility of the reverberation chamber to be extended to the frequencies considered for 5G.

INVITED SESSION PAPERS This talk introduces recent developments in the signal processing aspects of ultra-wideband (UWB) radar technology for measuring human bodies. Ultra-wideband radar has various applications, including measuring body shape and action types, and even remotely measuring vital signs such as respiration and heartbeat. This talk covers several advanced signal processing techniques, which are applicable to UWB radar data for retrieving information about the subject. Near-field radar imaging technology is currently used for body scanners at airports intended to detect concealed weapons. Our techniques enable us to generate high-quality radar images quickly, which is crucial for real-time applications. Another technique we have been developing is related to noncontact measurement of vital signs, which could be a breakthrough in the recent trend of health-conscious gadgets. Our signal processing helped us to achieve an unprecedented level of accuracy in the noncontact measurement of instantaneous heartbeat intervals using a multiple-input multiple-output UWB radar system.

INVITED SESSION PAPERS The effects of the propagation of radio waves in the atmosphere can be relevant for a number of Satellite services, including Satellite Communication (SatCom) systems, Global Navigation Satellite Systems (GNSS), Earth Exploration and Space Exploration systems. In particular the lower part of the atmosphere (i.e. the troposphere and to some extent also the stratosphere) induces several propagation effects, including attenuation, depolarisation, signal scintillation, noise emission, excess path length. These effects are relevant in all phases of a Space project, including preliminary and final design, in-orbit tests and operations. The effect of atmospheric propagation on Satellite services becomes more relevant as technological developments opens new frequency bands (see evolution of SatCom frequency bands from C up to W band), improves the performances of system components making more critical for the link budget the random contribution of atmospheric propagation or the system requirements impose a trade-off between system performances and system margins (e.g. between maximisation of data throughput and minimisation of system unavailability). In this framework the criteria for system design and control have to evolve from a classical static approach towards flexible and adaptive methodologies. This implies also the need to improve channel assessment techniques and to minimise the error of experimental measurements.This talk will present an overview of developments and channel modelling used by the European Space Agency in the framework of a number of ESA projects, including the Alphasat Aldo Paraboni (TDP5) experiment for SatCom services at Q/V band, contribution to Radio Regulations (ITU-R SG3), the development of models of tropospheric error for Galileo GNSS and its evolution, the use of Ka band for Earth Exploration missions (like METOP-SG) and support to radioscience experiments of Space Exploration missions (like Bepi-Colombo and JUICE, to Mercury and Jupiter).

INVITED SESSION PAPERS Gap waveguide technology is based on the control of wave propagation by using periodic structures. This technology, derived from the metamaterials and artificial surfaces background, has been employed during the last seven years to develop new antenna system components. The main advantage is the compromised low loss characteristic/low cost feature, provided by the possibility of using only metal and the non required electrical contact. Consequently, the technology has a lot of potential to be use in the millimeter wave frequency range. Along these years, classical antenna designs have been revisited using this technology as for instance slot arrays or leaky wave antennas but also other system components such as filters, diplexers or feed networks. A global overview of the technology, the different metasurfaces to be used and mainly the state of the art in terms of antenna designs making use of it will be presented in the talk.

INVITED SESSION PAPERS For more than last forty years, terahertz components and instruments have primarily been developed for space science applications in radio astronomy and planetary sciences. However, in recent years, terahertz waves are increasingly being used in commercial applications such as high speed communications, security imaging, autonomous landing and refueling of airplanes, and medicines. In spite of all these fascinating scientific and commercial potential, the terahertz frequency range (loosely defined as 300 GHz < ν < 10 THz) still remains one of the least utilized electromagnetic bands because of the unavailability of commercial source and sensor components, and sub-systems. Recent progress in CMOS technology as well as availability of InP HEMT based amplifiers in terahertz frequency band has caught the imagination of researchers for developing terahertz instruments for commercial applications as well. Rapid progress in multiple fronts, such as commercial software for component and device modeling, low-loss waveguide circuits and interconnect technologies, silicon micromachining for highly integrated and compact packaging, and submicron scale lithographic techniques, is making it an exciting time for terahertz engineers and scientists. In this presentation, an overview of the state of the terahertz technology will be presented. The talk will detail the science and other applications that specifically require technology at terahertz frequencies. The challenges of the future generation instruments, detectors, and antennas at these frequencies in addressing the needs for critical scientific and commercial applications will also be discussed.

CONVENED SESSION PAPERS Microwave imaging is a rapidly evolving modality. Microwave imaging systems have had clinical trials, but these typically require a lengthy regulatory approval process, numerous volunteers, and healthcare professionals. To allow for rapid yet realistic evaluation and refining of microwave imaging algorithms and systems, high-quality phantoms that mimic both the complex structure and dielectric properties of breast tissues are required. This work presents a design process that allows for breast phantoms to be modeled after MRI scans, along with a validation of the manufactured phantoms. The dielectric properties of the phantom materials were tested to ensure that they were similar to the properties of breast tissue. Breast phantoms were 3D-printed using the extracted MRI data and were tested using a clinical breast microwave-radar imaging system. The collected data were reconstructed using a holography algorithm that compensated for tissue density changes by adjusting the propagation speed.

CONVENED SESSION PAPERS Magnetic nanoparticles have been recently proposed as a contrast agent for breast cancer microwave imaging. In this communication, we report on the ongoing activities aiming at the feasibility validation of magnetic nanoparticles enhanced microwave imaging. In particular, we discuss the results of some experiments, carried out to deal with the factors that influence the detection limits of the technique. Previous experiments have shown that a major limitation to the minimum amount of contrast agent that can be appreciated is due to the instrumental drift, which cannot be overcome by simply averaging the measurements. In addition, owing to the low level of the useful signal, possible magnetic effects arising from the system and the involved media can become relevant and impair the measurements. In the following, we deal with these aspects and describe how to overcome them, while preserving the detection capabilities of the technique. Results from relevant experiments are presented.

CONVENED SESSION PAPERS This paper presents design considerations for the development of wide-scanning antennas for on-craft satellite communications. A scanning coverage of 80⁰ is required over a 15% bandwidth in Ka-band. A solution based on a phased array illuminating a passive superstrate is identified as the most promising. A fully-electronic beam-scanning is considered to reduce the overall thickness of the antenna architecture by avoiding mechanical rotational supports. This is beneficial since a reduced thickness corresponds to a lower drag. Two kinds of superstrates were investigated, a flat solution and a flattened dome. In both cases, the deflecting structure is illuminated by a phased array and is represented as a surface characterized by a phase shift distribution that allows to maintain high gain up to very large scan angles. A flatter gain profile compared to a typical cosine scan loss for planar phased arrays was achieved in both cases.

REGULAR SESSION PAPERS This paper proposes the performance comparison of two different corrugated feedhorns and their corresponding feed chains working simultaneously in the X and Ka frequency bands. One of the solutions is composed of an X band coaxial corrugated horn that combines axial and radial corrugations fed laterally by an OMTJ formed by four branches to allow dual polarization and a smooth-walled spline-profile Ka band horn antenna placed inside the inner coaxial of the corrugated X band horn. The second solution is formed of a radial corrugated horn antenna for Ka band connected directly to another horn antenna that combines axial and radial corrugations for X band.

REGULAR SESSION PAPERS This paper describes a Ku band, electronic beam steered array, operating at 10.7 GHz to 12.7 GHz intended for satellite DVB reception. The beam steering operates in the azimuth plane and the antenna also has a fixed beam squint at 23 deg elevation. This allows the antenna to be mounted vertically on a wall. Therefore the mounting can be very discrete, with less than 1cm protrusion from a wall in comparison to much bulkier parabolic dish antenna solutions. The relative simplicity and low profile of the antenna has been made possible by the use of COTS Ku band IC's, combined with novel analogue IF beamforming circuits. The antenna has been shown to be capable of receiving commercial DVB satellite signals transmitted from the Astra satellite in the UK. The antenna has dimensions of 25x37cm and is less than 1cm thick. It has a measured G/T of 7dB/K Neil Buchanan 537661 Queens University Belfast United Kingdom 1 Vincent Fusco 133875 Queen's University Belfast United Kingdom 0 Arpan Pal 941449 Swansea University United Kingdom 0 CS36 Charac Modes I CS36 Practical Applications of Characteristic Mode Theory to Antenna Design 23 March 2017 16:50-18:30 2017-03-23T16:50:00+01:00 2017-03-23T18:30:00+01:00 Oral Sessions: Room 342A 16:50 17:10 1570314961 CS36 Charac Modes I.1 Antenna Design for Smartphones Using Modal/Eigenmode Analysis 2.

Here, a review of the underlying design fundamentals is outlined. Next, a design example featuring the antenna design of a modern smartphone is presented. The design cycle is simplified through finding an antenna with appropriate complex resonance frequency to cover a required band. Locating the appropriate feed position is then a matter of extracting the corresponding impedance map for this antenna.

CONVENED SESSION PAPERS In this paper, we report the results of a preliminary study of the design of dual-band platform-mounted antennas. In this approach, appropriately-designed coupling elements are employed to excite a desired platform mode to obtain an operating band in the HF frequency range. Moreover, the coupling elements are also designed to act as ultra-wideband radiators within the VHF frequency band. The coupling elements are modified loops with two feed points, one at each end of the loop and they can be excited either in the common or in the differential mode. When the coupling loops are fed differentially, they excites the fundamental mode of the platform resulting in an HF NVIS antenna. On the other hand, exciting the coupling loops in the common mode allows them to radiate as a vertically-polarized, omni-directional ultrawideband radiator operating in the VHF frequency band.

CONVENED SESSION PAPERS In this paper, by using the Theory of characteristic modes (TCM), we analyze the effect of Inductive Coupled Elements (ICE's) used for the excitation of Characteristic Modes (CM) on antenna chassis. ICE's are used in sets to excite chassis modes and are placed at current maximas of the desired modes. Using TCM analysis, it was found that the introduction of such ICEs significantly affect the CM of the chassis and therefore can not be used as an efficient method for the excitation of CM. In addition, CM are compared with the total current generated on the surface and vicinity of a PIFA antenna. For normal excitation (not taking into account a single CM), a combination of modes are excited on the antenna chassis and surface depending on the frequency of interest. Also these currents are localized around the antenna. Asim Ghalib 1077641 King Fahd University of Petroleum and Minerals Saudi Arabia 1 Mohammad S.

These include, among others, excitation of the Characteristic modes on complex platforms; antenna placement on these platforms to achieve a desired radiation pattern, specified over a limited angular range; determining excitation coefficients of antennas to achieve interference suppression of unwanted signals. It then goes on to present some systematic approaches to addressing these problems by modifying the conventional Characteristic mode analysis in a suitable manner.

REGULAR SESSION PAPERS Carbon Fiber Reinforced Polymer (CFRP) or generally Carbon Fiber Composites (CFC) are increasingly utilized in lightweight construction. Large CFRP parts such as chassis or fuselages are utilized as antenna ground planes. However, radiation characteristics of antennas designed for metal ground planes change when mounted on anisotropic composites. In this paper the influences of CFRP ground planes on the radiation characteristics of antennas in the range from 1 - 10 GHz are investigated with measurements of conical monopole antennas. Measurements show that ground planes from unidirectional CFRP severely distort radiation patterns, while the influence of woven plies is small.

REGULAR SESSION PAPERS In this paper the detection of Orbital Angular Momentum (OAM) modes at a carrier frequency of 10 GHz is evaluated by modelling and by experimentation. A 2-element antenna array and the phase gradient detection method is used to determine whether a mode 0 or -1 is present, where our results verify that a distinct difference in measured phase profile between the two modes is distinguishable even in the presence of a multipath reflection. The measured influence of the multipath reflection is shown to agree well with modelling results. Our model combines full-wave simulations of transmit and receive antennas with a ray tracing model, revealing the respective influence of the direct and reflected multipath components of the signal. Consequently, our work shows novel insights confirming the behaviour of an OAM radio signal with a dominant reflected component and subsequent performance of the detector through experimentation.

A coaxial tube method (employed in EM solver) is used as emulation tool, with simulation and optimization performed in WIPL-D software suite. The material in question was selected as TDK IB-017. With the advanced mathematical model for the EM properties, a better agreement can be achieved.

REGULAR SESSION PAPERS In existing exposure standards and guidelines the relationship between dosimetric quantities at a given frequency is not always consistent as some simultaneously applied limits are more restrictive than others, e.g. limits on induced currents compared to those on external electric field or specific absorption rate (SAR). To evaluate the current induced in the human body in 1 - 90 MHz range, we propose an equivalent circuit composed of two elements: the first one provides the voltage at human body mid-height and the second one describes the equivalent human body impedance. Then, assuming that the human body is equivalent to an antenna between 1 and 90 MHz, we calculate induced currents at the human body height. Using the relationship between external electric field and voltage at the body mid-height, we calculate the current along the body and suggest updated limits on induced currents more consistent with the external electric field limits.

REGULAR SESSION PAPERS In this work, we report complex permittivity measurement of thick paraffin films at the frequency range of 26 GHz - 1 THz. Paraffin is a low loss dielectric polymer that exhibits 15% volumetric change through its solid-liquid phase change. Unique electrical and mechanical properties of paraffin makes it an attractive phase change material for the development of millimeter wave (mmW) and terahertz (THz) reconfigurable RF components such as variable capacitors and antennas. We employ a free-space measurement technique using time domain spectroscopy (TDS). Complex permittivity of paraffin is characterized over the frequency range of 26 GHz - 1 THz by using Debye relaxation model to extrapolate the measurement data for lower frequencies. Measured relative permittivity of paraffin is 2.26 and loss tangent is measured to be 1.57e-4 at 26 GHz and 0.006 at 1 THz.

REGULAR SESSION PAPERS The simulation of EM (electromagnetic) wave propagation requires considerable computation time, as it analyzes a large number of propagation paths. To overcome this problem, we propose a GPU (graphics processing unit)-based parallel algorithm for VPL (vertical plane launch)-approximated EM wave propagation. The conventional algorithm computes the gain along propagation paths with irregular memory access, which results in low GPU performance. In our proposed algorithm, a CPU reorders irregular propagation paths to a GPU-suitable linear order on the CPU memory at each receiving point. We hid the reordering time behind CPU-GPU communication and GPU-based computation of gain on the reordered memory. We found that our proposed algorithm with a quad GPU is up to 30 times faster than the conventional algorithm with a 16-threaded dual CPU.

REGULAR SESSION PAPERS This paper presents a new approach to compute the image tree of given order of ray interaction for ray-tracing. The intra-visibility of walls and vertical edges along with their angular position in the visibility region is computed. The image tree is readily created as the angular information is used to determine if a wall or vertical edge lies within an image illumination zone. Validation results show a considerable reduction in run times for image tree computations. The elimination of a recursive visibility algorithm for image tree creation is a first step towards efficient ray-tracing in mobile transmitter scenarios such as in vehicular networks.

REGULAR SESSION PAPERS Radio frequency (RF) propagation is highly dependent upon the vertical distribution of moisture and temperature along the transmission path. Vertical gradients in the atmosphere can alter normal propagation, producing sub-refraction, super-refraction or trapping conditions. The U.S. Navy employs a high resolution numerical weather prediction (NWP) model to forecast these gradient structures and their mesoscale variability. In this research we explore the fidelity of propagation loss predictions obtained using an NWP environment with measured data collected during the Tropical Air-sea Propagation Study (TAPS), a campaign that took place off the northeastern coast of Australia in Nov/Dec 2013 [1]. We demonstrate good agreement with Ka-Band path loss prediction to those received by a ship mounted MIMO system for ranges up to 45-50 km from the shore-based transmitter and investigate relationships between propagation loss, the evaporation duct height, and environmental parameters.

REGULAR SESSION PAPERS For applications of 5G (5th generation mobile networks) communication systems, dual-polarized patch array antenna operating at 28.5 GHz is designed on the package substrate. To verify the radiation performance of designed antenna itself, a test package including two patch antennas is also design and measured its scattering parameter. Using a large height of dielectric materials, 1.5 ~ 2.0 GHz of antenna bandwidth is achieved which is wide enough. Besides, the dielectric constants are reduced to reflect variances of material properties in the higher frequency region. Measured results of the test package show a good performance at the operating frequency, indicating that the fabricated antenna package will perform well, either. In the future work, manufacturing variances will be investigated further. Jin-Kyoung Du 1449114 LG Electronics Inc. Korea 1 Kwangsup So 1449118 LG Electronics Inc.

REGULAR SESSION PAPERS We present here a new design of a substrate-integrated waveguide (SIW), which is based on the use of a metamaterial-inspired periodic structure of coupled complementary split-ring resonators (CSRR). The resonators are etched on the metal surfaces that cover both sides of the dielectric substrate. The strong interaction between two side-by-side placed CSRRs provides the necessary means to block propagation through the ring structure and completely replace the series of via posts that is characteristic of a conventional SIW. The proposed transmission line has excellent propagation characteristics, since propagation losses are kept at levels comparable to those of the classic SIW, while the fully planar structure and the associated ease of implementation render the proposed SIW a strong alternative for a cost-effective implementation of millimeter-wave circuits and antennas.

REGULAR SESSION PAPERS We report multiphysics simulation of paraffin variable capacitors integrated with bent slot antenna to form a frequency reconfigurable structure. Paraffin is a low dielectric loss, phase change material that its solid-to-liquid transition exhibits 15% volumetric change. Here, we introduce low-loss paraffin phase change material (PCM) capacitors at 100 GHz that are monolithically fabricated with antennas. A frequency reconfigurable slot antenna loaded with paraffin PCM capacitors is designed that is capable of continuous frequency tuning in the range of 97.5-103.5 GHz. Antenna has a maximum gain of 3.78dBi and it is constant over the reconfiguration range. Actuation mechanism is analyzed in a multiphysics simulator. To characterize the deflection profile and the temperature distribution, it is crucial to fully couple the electric currents, heat transfer and solid mechanics. A new fabrication method for the deposition of the thin paraffin film is developed and a fabrication process for the reconfigurable antenna is presented.

REGULAR SESSION PAPERS In this paper, the generation of twisted pulses carrying orbital angular momentum is discussed. Such pulses are generated by polychromatic superposition of higher-order Bessel beams. The non-negligible effect of the wavenumber frequency dispersion on the pulse propagation at millimeter waves is taken into account. Large operating bandwidths are required to synthesize spatially confined electromagnetic pulses. For this reason, a wideband Bessel-beam launcher is proposed, implementing an inward cylindrical traveling-wave aperture distribution with an azimuthal phase variation. Preliminary results clearly show the possibility of successful generation of twisted electromagnetic pulses at millimeter waves.

REGULAR SESSION PAPERS The abundance of mobile wireless devices is giving rise to a new paradigm known as Internet of Things. Since the wireless sensing devices will be oriented randomly in the environment, they should be able to communicate equally in all directions in order to have stable communication link. Hence, compact near isotropic antennas are required, which can enable orientation insensitive communication. In this paper, we propose a simple design methodology to design a compact near-isotropic wire antenna based on equal vector potentials. As a proof of concept, a quarter wavelength monopole antennas has been designed that is wrapped on a 3D-printed box keeping the vector potentials in three orthogonal different directions equal. By optimizing the dimension of the antenna arms, a nearly isotropic radiation pattern is thus achieved. The results show that the antenna has a maximum gain of 2.2dBi at 900 MHz with gain derivation of 9.4dB.

Approximate closed-form solutions of the integral equations for narrow strip antennas are obtained for practically important situations. It is concluded that the replacement of a magnetoplasma by a relatively simple model of uniaxial medium almost does not affect the description of the characteristics of the considered narrow strip antennas.

REGULAR SESSION PAPERS The design of a wideband, vertically polarized omnidirectional dipole antenna based on a non-uniformly segmented structure is presented. The proposed non-uniformly segmented configuration mitigates the phase change of the currents flowing in the long dipole arms, so that the reverse currents which deteriorate the radiation pattern can be avoided, and a stable omnidirectional pattern can be maintained over a wide frequency band. Simulation results show that the proposed dipole has a wide pattern bandwidth of 66%, ranging from 1.96 GHz to 3.90 GHz, with S11 less than -10 dB. Within the band, the main lobe of the dipole remains in the broadside direction in the E-plane and the antenna achieves the desirable omnidirectional radiation pattern, with a gain flatness of less than 0.3 dB in the H-plane.

REGULAR SESSION PAPERS A low profile unidirectional UWB antenna for multi-service base stations is presented in this paper. The main goal of this article is to design a low profile UWB antenna with a very stable and unidirectional radiation pattern. The proposed design is based on exciting the fundamental mode of a planar structure composed of two metallic rings, applying the Theory of Characteristics Modes(TCM). The feeding structure used to excite that mode is asymmetric and it is implemented with two CPW-ports (Co-planar Waveguide) with an impedance of 50Ω, that bifurcate into two transmission lines with different lengths that are coupled to a circular aperture using the slot line model. The design has been obtained using a mathematical formulation, so it can be easily scaled to any frequency. Additionally, an analysis of the operation of the structure is performed, according to TCM. The -10dB bandwidth obtained is 64.22%, with unidirectional radiation patterns.

REGULAR SESSION PAPERS Experimental evaluation of a Ground Penetrating Radar (GPR) system is presented. The method is based on an Underground-SAR imaging algorithm that takes into account the complex permittivity of the soil to compensate for the slower wave propagation so that buried objects are imaged at the correct depth. The proposed GPR imaging system is devoted to operate in C band, from 3.5 to 5.5 GHz, in order to enhance lateral resolution thanks to the higher operating frequency. The 2 GHz frequency bandwidth enables 7.5 cm range (or depth) resolution. Several cases with different Tx/Rx hardware and antennas have been tested in order to analyze the influence in the recovered SAR images. 2D-MoM simulations have been done to evaluate the agreement with experimental results as well.

REGULAR SESSION PAPERS In addition to image processing and neural network, inverting the Geophysical Model Functions (GMFs) is one of the most widely used ways to retrieve oceanic parameters, i.e. surface wind speed, temperature, salinity, etc., from Synthetic Aperture Radar (SAR) data. More exact the description of the GMFs is, more accurately the results are obtained. For this problem, one can find two principal approaches: empirical (EP) GMFs based on in situ measurements and electromagnetic (EM) GMFs based on EM calculations of radar scattering from sea surface roughness. In order to explore the potentials of the GMFs for inverse problem in C-band, we compare in this paper radar scattering calculated by CMOD5.N (EP GMF), and TSM and SSA (EM GMFs). Likewise, we compare wind speed estimates by inverting the studied GMFs. Based on comparisons, several solutions may be proposed to improve the calculation of radar scattering, and then the retrieval of oceanic parameters.

Leveraging the computational imaging concept, the frequency-diversity enables imaging in an all-electronic manner, without the need for mechanical raster scanning or active circuit components, minimizing the data acquisition time and simplifying the system architecture.

REGULAR SESSION PAPERS This paper deals with the polarization aspect in 3D inverse scattering. The vectorial information contained in the scattering matrix is often under-exploited in quantitative inverse scattering problems even if it has been expensively studied in radar processing. In this work, we present a study of the influence of the polarization state of the electromagnetic wave on the reconstructed permittivity maps. Reconstructions performed from measurements in different polarization cases will be compared and discussed.

REGULAR SESSION PAPERS It is important to know which parts of an inspection domain could be suitably reconstructed in through the wall imaging (TWI). It is also of interest to find a frequency range for which a reconstruction algorithm is efficient. For these purposes, a quantitative investigation of the coverage area and frequency bandwidth of the imaging setup is introduced. The imaging process is based on the linear sampling (LSM) as a well-known qualitative method in the literature. The method is very effectual since it is fast and robust against noise. We need the background Green's function for the realization of LSM which is derived recently by the authors. The frequency bandwidth of the imaging algorithm would be obtained by calculation of a resemblance coefficient (RC) for the various frequencies. Here we also define a new parameter named coverage area (CA) and discuss a scenario to find it.

REGULAR SESSION PAPERS In this paper, we present the theoretical considerations for the implementation of a single layer anisotropic metasurface (MTS) antenna capable to provide different circularly polarized radiation patterns at two frequencies at Ku band (13.5GHz and 16GHz). Circular metallic subwavelength patches with a groove through the diameter are employed to synthesize the proposed MTS configuration. At lower band broadside radiation with a maximum directivity of 26.5dBs is obtained, with 28dBs cross polar field component. At higher band, isoflux-shaped radiation pattern with a drop-off angle around 33 degrees and 10dBs cross polar field is obtained.

REGULAR SESSION PAPERS This paper presents a modal field-based approach for an initial design of low cross hybrid mode conical horns with engineered metasurfaces (MTSs) as sidewalls, described through equivalent surface impedances, referred to as MetaHorns (MTHs). The proposed method overcomes the intrinsic non-separability problem in conical structures with arbitrary walls through an adiabatic local mode approximation. By exploiting the fundamental mode adiabatic propagation characteristics as input for MTS design, the approach provides a good starting point for the design of MTHs with symmetric radiation pattern and low cross polarization. The quasi-analytical nature of the method assures a physical insight on MetaHorn behavior, resulting in a better control on design process, lightning optimization algorithms and full wave simulations, which can be thus used in a subsequent step as refinement of the antenna synthesis process.

REGULAR SESSION PAPERS This paper describes the design and realization of a modulated metasurface (MTS) antenna at 300 GHz. To overcome the hurdles associated with the use of dielectric substrates in the sub-millimeter wave range, we propose an MTS structure which consists of an array of metalized cylinders placed on a ground plane. The metal cylinders are arranged in a square lattice with sub-wavelength unit cell size. This MTS topology has been successfully used to design a spiral MTS antenna. The resulting structure has been micromachined out of a silicon wafer by means of deep reactive ion etching (DRIE). The performance of the antenna has been verified by full-wave simulations, and measurements will be available at the time of the conference.

The proposed miniaturization method consist in transforming the electrical filled square dipoles into vertical folded square loops. The surface of the radiating element is reduced to 0.23λ0*0.23λ0, where λ0 is the wavelength at the lowest operation frequency for a standing wave ratio (SWR) <2.5, which corresponds to a reduction factor of 48%. The antenna has been prototyped using 3D printing technology. The measured input impedance bandwidth is 51.2% from 1.7 GHz to 2.9 GHz with a Standing wave ratio (SWR) <2.

REGULAR SESSION PAPERS The resistively loaded 3D printed antenna demonstrates that commercially available thermoplastic filament which incorporates carbon particles can be used to print the radiating element directly, without any need to coat it with metal. Antennas used for Ground Penetrating Radar are generally resistively loaded in order to minimise late-time ringing which would obscure the returns from targets. Therefore radiation efficiency is not expected to be high. Wideband operation and good directivity are desirable characteristics of air-coupled GPR antennas, as realised here using a low cost fused filament 3D printer.

Additionally while the resulting physical antenna properties may not be perfect compared to the design or what can be machined, their RF/microwave performance can be quite forgiving thereby allowing the antenna design engineer to fully exploit the rapid prototyping concept.

REGULAR SESSION PAPERS A dual band antenna is inkjet-printed and then folded as part of a paper unmanned aerial vehicle (UAV). The patterns of the antenna are reproduced on a standard photo paper substrate using an off the shelf inkjet printer. Readily available cartridges with nanoparticle silver conductive ink are employed. A single-layer planar antenna is fed by coplanar waveguide (CPW). The geometry of the radiating element consists of a semicircle with a centered square slot. In order to examine the effect of bending on performance, the antenna is tested unfolded and then folded when integrated onto the airplane. Two configurations of the folded antenna on the plane are analyzed. The aim is to investigate the feasibility of fabricating foldable antennas for paper airplanes using low-cost inkjet printing techniques.

CONVENED SESSION PAPERS This paper presents a study into the effect of receiving antenna orientation and polarization on the measurement of antenna efficiency for electrically small antennas (ESAs) in a reverberation chamber (RC). Throughout the measurements, the same transmitting antenna was used whereas the receiving antenna was either the antenna under test (AUT) or a reference antenna (REF) of known efficiency. A series of measurements were made for various combinations of AUT and REF antenna orientations and polarizations. The obtained radiation efficiency results are compared. The AUT used for this study was an electrically small dielectric resonator antenna (DRA). The results show that differences in measured efficiency of up to 2 dB (i.e. 40%) can arise due to different AUT and REF orientations and polarizations.

CONVENED SESSION PAPERS This paper focuses on enhancing multiband isolation between two antenna elements in a reconfigurable multiple input multiple output (MIMO) system. The antennas are reconfigurable printed inverted F antennas (PIFA) that resort to two PIN diodes each to achieve frequency reconfiguration. The isolation between the antenna elements is proposed to be improved through the use of multiple nested slots in the common ground plane between the elements. These slots collectively act as a multi-band reject filter and improve the isolation at the various operational frequencies of the antenna system. The reconfigurable MIMO antenna system is proposed for integration into mobile devices with an operation that covers mobile communication applications.

CONVENED SESSION PAPERS Clinical studies have established that adjuvant mild hyperthermia significantly increases the efficacy of radio- and chemotherapy across many tumor sites. Radiofrequency hyperthermia treatment quality is usually monitored with invasive temperature sensors, which provides limited data sampling and causes infection risks. To mitigate these issues, magnetic resonance (MR) measurements can be exploited for 3D thermal dose assessment during treatment. To this end, a number of novel hardware approaches have been proposed to combine RF heating and imaging more effectively. In this work, we review the status of MR guided radiofrequency hyperthermia, including the electromagnetic inter-systems interactions.

CONVENED SESSION PAPERS A parasitic superdirective electrically small coil array based on printed loop antenna for magnetic resonance imaging (MRI) applications is presented. The proposed coil array is composed of two coils wherein one of the coils is excited and the other is loaded with a tuning capacitor acting as a director to generate directional near-field distribution. The coils are with identical diameter of 30 mm and are positioned with a distance of 12.5 mm (0.0125 wavelength at 300 MHz). An antenna prototype exhibits directional field distribution and more than 3-dB enhancement of magnetic field intensity compared with a conventional single loop coil antenna with identical size. The proposed directional coil is used as the RF receiving coil for a 7T MRI system, it increases the signal-to-noise ratio (SNR) and penetration level of the system.

CONVENED SESSION PAPERS Hyperthermia therapy is a promising method of cancer treatment, where cancer cells are killed via moderate heat exposure. Magnetically mediated hyperthermia (MMH) is based on the heating of particles or implants, by an externally applied alternating magnetic field. Some MMH systems use induced eddy currents as heat sources. Their operation is very similar to that of wireless power transfer (WPT) systems. Hence, optimization techniques aimed at maximizing the power transfer efficiency of WPT systems can be adapted to optimize heating efficiency in MMH. This paper provides the theoretical framework of this new route to designing MMH systems and analytical results for their optimal heating efficiency. Full-wave electromagnetic simulations further demonstrate the viability of the proposed MMH approach.

CONVENED SESSION PAPERS Microwave thermal ablation is under consideration for minimally invasive treatment of bilateral adrenal adenomas, symptomatic of Conn's syndrome. Currently available microwave technologies are ill-suited to precise ablation of small adrenal targets. We report on our preliminary computational and experimental efforts towards the design of microwave ablation systems for targeting adrenal masses. Broadband dielectric properties of ex vivo bovine adrenal glands were experimentally measured. Computer simulations demonstrated the feasibility of achieving precise ablation of adrenal lesions with 2.45 GHz systems. Experiments in ex vivo adrenal tissue using a water-cooled 2.45 GHz antenna illustrated the feasibility of heating 10-20 mm adrenal targets with 40 W power applied for 1 min. These preliminary results warrant further investigation and development of microwave technology for precise ablation of adrenal masses.

CONVENED SESSION PAPERS Microwave ablation (MWA) is widely recognized as a promising treatment tool for cancer. To ensure an effective and safe treatment, real-time monitoring of the dimensions of the ablation zone is indispensable. In this paper, we propose a microwave imaging algorithm for monitoring the evolution of the ablation zone. This algorithm estimates the boundary of the ablation zone by exploiting the time difference of arrival (TDOA) between pre- and during- ablation signals. A notable advantage of this method is that it requires few assumptions about the spatial distribution of dielectric properties of the propagation media. We investigate the performance of this approach using simulated array measurements obtained from FDTD simulations of MRI-derived numerical breast phantoms. The results demonstrate that our proposed method offers the potential to achieve millimeter order accuracy in estimating the boundary of the ablation zone in heterogeneous and dispersive breast tissue.

CONVENED SESSION PAPERS In this communication, we present a full-wave numerical study aimed at showing the potential of microwave tomography as a tool to monitor microwave ablation of solid tumors. The goal is to track the changes in dielectric properties of the tissue undergoing the treatment, in order to appraise the evolving dimension and shape of the thermally ablated area surrounding the applicator. Such an in-line monitoring capability would entail a significant improvement in the therapeutic effectiveness of cancer treatments exploiting microwave ablation, both in terms of optimization/personalization of the therapeutic protocol and of reduction of unwanted side effects due to the unwanted increase of temperature in healthy tissues. The numerical study involves a scenario inspired by an existing experimental set-up, already used for the ex-vivo assessment of microwave ablation treatments. Hence, the promising results we have obtained, fully motivate us to progress towards the experimental demonstration of the concept in ex-vivo conditions. Gennaro G.

CONVENED SESSION PAPERS An efficient spherical NF/FF transformation for an offset mounted AUT, with a quasi-planar shape, employing a number of NF data minimum and practically equal to that for a centred mounting, is developed. This result has been achieved by applying the nonredundant sampling representation of electromagnetic fields to the voltage collected by the probe and considering the AUT as contained in a double bowl. The interest for this transformation is due to the fact that sometimes an AUT mounting centred on the scanning sphere centre cannot be possible. In such a case, the number of NF data required by the classical NF/FF transformation can remarkably increase, owing to the growth of the minimum sphere radius. In the considered approach, the NF data required by the standard transformation are accurately recovered from the nonredundant ones by employing a 2-D optimal sampling interpolation algorithm. A remarkable measurement time reduction is so obtained.

Publications on the more general problem of phase retrieval have been able to state conditions on the number of amplitude measurements required for various algorithms to find the globally optimal solution. In this contribution, a possible and practical approach of acquiring the necessary amplitude measurements in terms of phase differences is presented.

CONVENED SESSION PAPERS Accurate spherical Near-Field antenna measurements are typically performed compensating for the probe pattern during the Near-Field to Far-Field transformation. Depending on the complexity of the probe modal content and on the required accuracy, different Probe Correction (PC) techniques can be applied. It is common practice to distinguish between first order PC, where only |μ|=1 spherical modes of the probe are compensated for, and full PC, taking into account the entire probe spectrum. Another key factor to be considered when applying the PC is the probe characterization. In order to obtain very accurate results, it is common practice to calibrate the probe in dedicated measurement campaigns which, unfortunately, can often be time consuming and expensive. Alternatively, the simulated probe performance can be used to perform the PC. A comparative investigation between full and first order PC performed using calibrated or simulated probe is presented in this paper.

NIST set out to develop an antenna measurement facility that would be reconfigurable to different near-field antenna measurement geometries and perform antenna measurements from 100 to 500 GHz. The positioning capability of the robot has been evaluated and spherical near-field measurements performed at 183 GHz. Spherical far-field and extrapolation measurements have been performed at 112, 118 and 125 GHz.

CONVENED SESSION PAPERS Accurate measurement of high directive antenna has always been a very challenging topic, especially at millimeter waves (mmW). MmW system are more efficient with a direct connection between the electronic circuits and the antenna. In order to characterize accurately the antenna, RF probe feeding is required and a specific measurement procedure is needed. In this paper, a dedicated set-up is described with near-field measurement capabilities for directive antennas. A 15*15 λ0 reflect array is measured as a proof of example.

CONVENED SESSION PAPERS Standard probes for near-field antenna measurements, open-ended waveguides, become bulky and heavy at lower frequencies, below about 2 GHz, that complicates their handling. This paper presents a practical design of a log-periodic dipole antenna (LPDA) specifically developed to possess low level of cross-polarization, to be used as a probe for near-field antenna measurements at frequencies below 2 GHz. The manufactured antenna has low weight and it is easy to handle. The covered frequency band is from 500-1100 MHz, which corresponds to two standard waveguide bands. The antenna can be easily scaled to lower or higher frequencies in the UHF band.

Although rigorous formalism exists, this formalism is not commonly used due to its complexity. Simplified equations are derived in particular antenna under test (AUT) polarizations and kind of probe corresponding to the most common cases. Application of the technique to a reflector antenna (about 30 dB @ 12 GHz) is described. Analysis of measured results is carried out to illustrate a comparison of accuracy of this technique with results obtained with a compact range.

CONVENED SESSION PAPERS Massive MIMO is a multi-user technology, where radio base stations (BSs) are equipped with a large number of antennas to simultaneously serve many terminals in the same time-frequency resource. Performance evaluation of such large-scale antenna systems in the design and development stage is challenging. In this paper, we propose to evaluate massive MIMO BSs with a sectorized multi-probe anechoic chamber (MPAC) setup. A sectorized MPAC setup with 16 probe antennas distributed uniformly within $[-60^o, 60^o]$ in azimuth domain is utilized to reproduce target channel models. A $8\times8$ and a $16\times16$ uniform planar array at 3.5 GHz are selected as the BS under evaluation, respectively. Radio channel emulation accuracies in terms of power-angular spectrum, spatial correlation and beamforming pattern are investigated for the proposed MPAC setup and desired channel models.

CONVENED SESSION PAPERS Two OTA test methods from literature are selected as those most suited for testing future 5G equipment when assessing end-to-end performance: coherent wave-field synthesis and radiated two-stage or "Wireless Cable". Both methods have their advantages and disadvantages. Wave-field synthesis is transparent for antenna characteristics of Equipment-under-Test but not viable for large test objects. The Wireless Cable puts no direct size constraint on Equipment-under-Test but requires antenna pattern measurements beforehand and cannot cope with dynamically adaptive antenna patterns. Other methods from literature show deficits regarding real-time testing or accuracy of the angular distribution of emulated radio fields. Wim A. Th.

CONVENED SESSION PAPERS This paper discusses physical dimensions for a multi probe anechoic chamber based (MPAC) over-the-air (OTA) setup aiming for base station (BS) testing. The target frequency of the simulated massive multiple-input-multiple-output (MIMO) BS arrays is 28 GHz. The assessment is performed with two metrics. The first metric is a new power metric based on assumptions of a code book of fixed beams and planar waves. The second one is the multi-user (MU) MIMO sum rate capacity. The intention is to evaluate physical dimensions in metres with respect to different BS array sizes. Simulation results indicate that OTA performance of a BS array with maximum dimension of 0.15m could be measured with a setup having measurement distance of approximately 1m.

CONVENED SESSION PAPERS The move of cellular communications from existing frequencies predominantly below 3 GHz up to the lower end of the mmWave bands around 28 GHz and higher, is set to change everything about how we design, test and operate such systems. The successful launch of a new radio (NR) access system is critically dependent on a correct understanding of the quasi-optical propagation behaviour of narrow beamwidth mmWave signals. The development of accurate channel models will correctly inform the NR specifications and equipment design, then finally the test requirements. However there is not yet consensus across these four domains on key parameters such as the number of usable beams, their angular width and their dynamics in terms of spatial consistency, power, time dispersion and frequency dependency. This paper examines explains the need to make coordinated progress across the industry to ensure a timely and technically successful deployment of mmWave 5G.

Considering the maximum side lobe level of a dense connected Vivaldi antenna array operating at a frequency and scan angle where a grating lobe is generated in the visible region, it is shown that introducing a separation between the constituent station tiles results in an initial reduction in the grating lobe level of approximately 8 dB. Further mitigation of the dispersed grating lobe power is demonstrated by solving the tied-array beam of 18 disconnected dense Vivaldi antenna stations rotated by 10 degrees with respect to each other.

CONVENED SESSION PAPERS Crossed Ring Antenna is using a 2-D planar structure design to form low cost aperture arrays. However, using the conventional PCB based conducting materials to build the radiating or receiving antenna surfaces for large scale applications, such as Square Kilometre Array, is still costly. 2-D material like printed graphene implemented by forming conductive ink with graphene nanoflakes can be a promising solution. It is superior for conformal structures and can be processed at low temperature, therefore low cost substrate such as textile, paper can be used for printing. On the other hand, mono or few layers of graphene is a moderate to bad conductive surface in the mm-waves and lower frequency.

REGULAR SESSION PAPERS We provide a complete and exact space-time system model for arbitrary antennas valid for generic field excitations. The method is based on introducing a time-dependent extension of the antenna current Green's function (ACGF). It is shown that this approach is more general than the conventional impulse response model by proving that for generic antennas an impulse response may not exist. A complete antenna-field-digital communication link is analyzed using the method and the optimum receiver structure matched to any given antenna and electromagnetic field illumination is derived.

REGULAR SESSION PAPERS In this work, the Intersection Approach algorithm is adapted to perform near field synthesis of reflectarray antennas. First, a brief description of how the near field radiated by the reflectarray is presented. Then, the algorithm is detailed, in particular, the definition of the forward and backward projectors. Unlike as the far field version of the Intersection Approach, for near field synthesis the backward projection cannot be implemented by a Fast Fourier Transform, and another strategy is employed, namely, the use of a general minimization algorithm, the Levenberg-Marquardt algorithm in this case. Finally, the algorithm is validated with a near field optimization consisting on generating a planar field amplitude in a volume for applications such as RFID tag identification or wireless short range coverage.

The antenna has three layers.The first one (feeding-layer 1) is practically identical to the second one (feeding-layer 2). This optimizes the design and facilitates manufacturing.The corporate-feeding networks on the two layers are rotated 90 degrees to each other to get the two orthogonal polarizations. Radiating elements are square apertures located on the top of the antenna. Simulated results show both impedance bandwidth and radiation pattern bandwidth greater than 15% for both polarizations.

REGULAR SESSION PAPERS Design and measurement of a planar radome absorber under oblique incidence are presented. The structure is composed of a bandpass multilayers frequency selective surface (FSS) combined with periodic cylindrical-shaped absorbers. This configuration made the resulting structure transparent at the intended antenna operational frequencies (C-band) and absorptive at higher frequencies (X-band). The prototype has been fabricated with a dimension of 24.5 cm × 24.5 cm × 0.65 cm. Performance under oblique incidence (without the antenna) is investigated using NRL arch technique in the absorption band. Reflection less than -10 dB is maintained in the range of 8.5 GHz - 11 GHz up to 40° incidence angle for incoming waves with perpendicular polarization. Under parallel polarization, the -10 dB reflection is achieved up to 50° in the range of 8 GHz - 12 GHz.

REGULAR SESSION PAPERS In the present paper, the Kirchhoff's Current Law (KCL) is re-considered as a cloaking condition for structures based on dielectric-plasmonic materials (Plasmonic Cloaking) and devices made up of metallic-dielectric metasurfaces (Mantle Cloaking). Consistently with Devaney-Wolf Theorem III on non-scattering sources, the KCL is derived by imposing zeros on scattered near-fields in the quasi-static limit: beyond the quasi-static regime, the KCL can represent a local condition on each unit cell of impedance metasurfaces. The aim of this paper is to introduce a unified physical-mathematical framework for invisibility and cloaking devices from a novel perspective based on contrast and impedance concepts.

REGULAR SESSION PAPERS This paper presents a novel solution to extend the scanning range of a cavity-backed stacked-patch phased array subject to scan blindness. Two main aspects are investigated. The first section is a thorough description of the scan blindness mechanism occurring in the reported array, taking into consideration the characteristics of the associated mutual coupling scheme. The second section introduces a revised array topology that allows extending the scanning range. The proposed solution is based on the switching between two operating modes of the structure, each one covering a distinct scanning range. Taken together, they potentially allow freeing the structure from scan blindness. In the present case, the scanning capability of the array has been extended by 10° in the scanning plane of interest.

REGULAR SESSION PAPERS — A novel high gain polarization switchable rectangular slot antenna is proposed in this paper. Antenna consists of a rectangular slot can be switched in three polarization states; left hand circular polarization (LHCP), linear polarization (LP), and right hand circular polarization (RHCP) by controlling the bias voltage of PIN diodes. The proposed antenna is fabricated on a RT/duroid 5880 substrate. Slots are etched on one side of the substrate, while the microstrip feed network is printed on the other side. A metal reflector is placed in a plane parallel to the slot surface to make radiation pattern unidirectional and hence increase the overall gain of the antenna. Measured results are well matched with the simulated ones. Measured 3dB axial ratio bandwidths for LHCP and RHCP are 125 MHz and 120 MHz, respectively. Measured gain of the antenna is around 7 dB at 1.2 GHz in all three states.

REGULAR SESSION PAPERS In millimeter and sub-millimeter wave imaging systems a persistent goal is the increase in sensitivity and Field-of-View of the system. Typically the highest sensitivity is achieved by cryogenically cooling the detectors, specifically in satellite based astronomic applications. However, good sensitivities can also be achieved by using tens thousands of receivers utilizing a very broad portion of the THz-band. This leads to uncooled integrated detection solutions suitable for low-cost imaging applications. In wideband systems the optimal sampling configuration will be a trade-off between imaging speed and resolution. In this contribution we will investigate the optimal sampling configuration in terms of imaging speed as function of bandwidth, considering the system is detector-noise limited. Using a leaky-lens FPA with a relative bandwidth of 1:5 results in an increase in imaging speed of a factor 45 w.r.t. a 1:1.5 horn antenna FPA, at the cost of a 4.17 times lower resolution.

REGULAR SESSION PAPERS This paper presents the description and analysis of a continuous parallel plate waveguide (PPW) lens-like beamformer. The main design parameters of the continuous delay lens are defined starting from an ideal bifocal constrained lens. A dedicated ray tracing analysis tool is developed to better describe propagation effects in the delay lens and provide more insight on phase aberrations versus pointing angle. Numerical results of a specific design at Ku-band are reported by comparing radiation patterns obtained with the ray tracing tool and a full-wave method. These results are also compared to the ideal bifocal constrained lens design.

REGULAR SESSION PAPERS Waveguides with anisotropic surface impedance boundaries have been investigated for the purpose of matched feeds for offset reflectors. Matched feeds employ higher order waveguide modes to cancel out cross polarization introduced by the offset geometry. Since the higher order modes propagate at different speeds than the fundamental mode in conventional waveguides, it is challenging to meet phase relationship requirements over a large band. We have found that traditional corrugated waveguides are poorly suited for matched feed applications. However, other surfaces that satisfy the balanced hybrid condition, but have a small capacitive longitudinal reactance and large inductive azimuthal reactance show very promising properties: In a large band, HE11 and HE21 have similar propagation characteristics.

CONVENED SESSION PAPERS Radars capable of measuring targets' polarimetric characteristics provide valuable supplementary information for a more reliable detection, identification and physical parameters estimation. The novelty of this work lies in that it had not been previously possible to perform measurements for a comparison of polarimetric orthogonal simultaneous vs time-multiplexed sequential sounding signals in real-time, because of the time delay required to reconfigure a system to cater for the different waveform types. During this time delay, an observed non-stable target(s) would have had substantially moved, yielding both measurements not directly comparable. In this paper we present the polarimetric interleaved simultaneous-time-multiplexed waveform, justifications for the PARSAX radar setup upgrade, and the system implementation with a focus on the receiver FPGA. Preliminary results from the comparison are revealed. The data and results will be used for a future detailed comparative analysis of sounding waveforms and their impact on polarimetric target characteristics Sharef Neemat 1448743 Delft University of Technology The Netherlands 1 Oleg Krasnov 460751 Delft University of Technology The Netherlands 0 Etienne Goossens 1448778 Delft University of Technology The Netherlands 0 Alexander Yarovoy 995973 TU Delft The Netherlands 0 11:10 11:30 1570313766 CS35 Polar & RCS.3 Polarimetric EM Simulation of Dielectric Radar Benchmark Targets 2. CONVENED SESSION PAPERS This paper studies the accuracy and limitations of different electromagnetic (EM) simulation approaches for dielectric radar benchmark targets. In comparison to perfect electric conductors (PEC), dielectric targets are much more complex from an EM point of view. However, dielectric materials are widely used for modern aircraft and unmanned aerial vehicles (UAVs). Apart from that, EM simulation tools nowadays play an important role in the design of aerial vehicles and radar systems. In order to evaluate the accuracy and performance of different EM simulation approaches, the results obtained using Physical Optics in combination with a ray tracing approach are compared to full-wave reference data.

CONVENED SESSION PAPERS Three-dimensional radar cross-section (RCS) images are a valuable support for understanding the scattering events occurring at a radar target. Traditional RCS measurement methods require a large angular range and many measurement points to provide sufficient resolution and unambiguousness. This paper proposes the usage of high resolution techniques, enabled by taking the polarimetric signal components into account. Therefore, the geometry of a compact antenna test range is explained and integrated into a signal model similar to the one of the direction of arrival (DOA) problem. Subsequently, a choice of prominent DOA algorithms are adapted and analyzed according to their tomographic RCS imaging performance. The validation of this approach is done by measuring a reference target's three-dimensional RCS. A comparison of the results of the conventional Bartlett-Beamformer to high resolution methods like Multiple Signal Classification (MuSiC) and Deterministic Maximum Likelihood (DML) is provided in the end, constituting the advantages of MuSiC.

CONVENED SESSION PAPERS This paper presents a new principle of a passive chipless RFID wireless sensor for a rotational motion measurement and identification. The sensing and identification principles are based on a high quality factor substrate integrated cavity (SIW) resonator with dual antennas at two different angles. Depending on the angle difference between the dual antennas, the backscattered power generates a unique and identifiable pattern, which encodes in time domain both the rotational speed and the signature code of the rotating object. By the utilization of different dual polarizations, different sensor tags can be created with identification capabilities allow to distinguish between different sensors. The sensor operation principle has been investigated experimentally for determining maximum number of possible codes using the response time of the reader. The choice of SIW for proposed sensor has the advantages of having Q factor and low insertion loss as well as compatibility with planar microwave circuit technology.

CONVENED SESSION PAPERS Internet of Things (IoT) is becoming a driving paradigm for the Information and Communication Technology (ICT) evolution. Beyond the well known sensing and communication features that must equip objects to become smart and thus to insert them into IoT world, energy autonomy and the largest compatibility with hosting objects must be pursued. Chipless sensor tags are one of the most promising solution to cope with all these features concurrently, since they are passive and can be easily implementable by using eco-friendly materials. The main limit of classic chipless architectures, however, is that they are usually static and in any case sensing information can be recovered only in presence of a stationary environment. This paper presents a review of some "multi-bit" sensor tag architectures based on the harmonic radar principle that can overcome this limitation and thus be profitably used to support the massive deployment of IoT devices.

REGULAR SESSION PAPERS In this work, we present an analysis of artificial dielectric layers (ADLs), when a lateral shift between layers is present. The alternate lateral displacement of the layers is an important parameter to engineer the desired effective electromagnetic properties of the ADL material. More specifically, much higher equivalent dielectric constants can be realized by alternatively shifting the layers, compared to the aligned case. Closed-form expressions are given for the equivalent layer reactance that include the higher-order interaction between shifted layers. These analytical formulas are of great aid to design artificial dielectric slabs, as they provide the scattering parameters for generic plane-wave incidence. The effective permittivity and permeability tensors of the artificial dielectrics can then be retrieved from the scattering parameters.

REGULAR SESSION PAPERS In this work we demonstrate three different designs of tunable mid-infrared (MIR) beam steering devices based on multilayer graphene-dielectric metamaterials. In all designs the tunable beam steering is achieved by controlling the effective refractive index of the graphene metamaterial, which is done by changing the chemical potential of each graphene layer. The proposed beam steerer concepts allow a wide range of output angles (up to approximately 70 deg) and low reflection losses. The graphene-based tunable beam steering can be used in tunable transmitter/receiver modules for infrared imaging and sensing.

REGULAR SESSION PAPERS We investigate the use of black phosphorus thin films in infrared plasmonics and discuss spatial dispersion effects. For appropriate film thickness, black phosphorus exhibits a moderate bandgap suitable for operation in this frequency band, and the intrinsic anisotropy of its conductivity tensor provides exciting possibilities in metasurfaces/reflectarray design, such as polarization-dependent devices and unusual topological transitions for plasmons induced by electrical or mechanical bias. We study the limits on plasmon confinement and field enhancement imposed by spatial dispersion and demonstrate that these bounds are looser than in graphene. These findings may lead to infrared plasmonic devices enabling light-matter interactions beyond the capabilities of other plasmonic materials, with exciting applications in sensing, thermal imaging, and heat scavenging.

REGULAR SESSION PAPERS A reactive impedance surface (RIS) based on graphene material is designed and analytically investigated using transmission line (TL) approach at terahertz frequency. Surface impedance behavior of the unit cell structure can be tuned by varying the chemical potential assigned in each circular RIS elements. A dipole antenna with a backed dielectric is mounted over a 8×8 RIS structure. It is observed that graphene-based RIS provides a miniaturized resonance alongwith good impedance matching and improved impedance bandwidth. The proposed structure reduces the back lobe of the conventional dipole antenna accompanying with a front-to-back ratio of 12 dB. A good co-pol and cross-pol isolation in both E-plane and H-plane is observed for the loaded structure.

REGULAR SESSION PAPERS A surface wave launcher in substrate integrated waveguide technology is proposed. The launcher utilizes a conventional microstrip to SIW transition with the motivation of transferring power into the dominant TM0 surface wave mode of a grounded dielectric slab. Moreover, by appropriate design of the SIW section and by applying field matching techniques using sub-wavelength microstrip patches while also conveniently separating some of the via conducting posts for one of the SIW side-walls, energy can leak into the GDS with minimal losses for the generation of a bound and guided TM SW plane-wave with a uniform phase front. Our new approach for simple, microstrip-fed SW launching at microwave frequencies can be useful for other SW-based guides, novel low-cost transitions, and new compact dividing/combing circuits for antenna feed systems as well as other SW structures which employ a common substrate.

REGULAR SESSION PAPERS The possibility to generate a nondiffracting Bessel beam by means of a fast backward spatial harmonic supported by an annular metal-strip grating placed on a grounded dielectric slab is demonstrated. The focusing capabilities of the relevant leaky-wave aperture field are investigated in conjunction with the dispersive analysis of the considered structure. Full-wave simulations of a prototype are developed using a commercial code.

REGULAR SESSION PAPERS In this paper we propose a circular leaky wave-antenna with omnidirectional radiation pattern in the H-plane. The design utilizes double-layered strips to create an end-fire antenna. A linear tapering of the stripes in the design endows the antenna with a 27% impedance bandwidth of 26.4-34.6 GHz. The antenna is vertically polarized with a cross polarization below -30 dB. The antenna has low gain variation in H-plane and it is compact as a planar structure. Furthermore, it can be easily fabricated and integrated by common PCB processing, which is very promising for applications such as base stations for wireless communication, spectrum monitoring and jamming systems.

REGULAR SESSION PAPERS A leaky-wave antenna (LWA) designed in substrate integrated waveguide (SIW) technology and showing high directivity in its transverse plane is presented. In addition, the proposed SIW LWA allows for the flexible control of its complex propagation constant, and thus of its radiation properties. For this purpose, the width of the SIW is used for the control of the phase constant and the separation between posts for the leakage rate. Moreover, the proposed structure works with the TE20 mode of the SIW, which makes it possible the radiated electric fields be added in phase at the center of the SIW, providing higher directivity in the transverse plane compared to single line-source antennas. Full-wave simulations are given to support the theoretical concepts exposed along the work. Furthermore, several prototypes have been designed at the frequency of 15 GHz to validate this work.

REGULAR SESSION PAPERS This paper investigates propagation mechanisms that EM side-channel signals experience at different frequencies and proposes models for near-field and far-field propagation of side-channel signals. The near-field propagation is modelled as a field created by an electric monopole (Hertzian dipole) and a magnetic dipole, where the received power is collected using only magnetic components of the EM field. This model resulted in excellent match with measured data. Furthermore, this paper investigates unintentionally modulated side-channel signals. The propagation of EM side-channel signals was modelled using free space propagation model which resulted in excellent match with measured data. In both cases we have observed that signal can be received at several meters from the side-channel source. The proposed models are the first step in understanding propagation mechanisms of EM side-channel signals and how to predict the distance at which they can be received.

REGULAR SESSION PAPERS This paper presents the study of electromagnetic wave propagation in anisotropic, lossy and strongly inhomogeneous magnetoplasmas of compact ECR-type ion sources. Due to the specific shape of the magnetostatic field (B-minimum configuration), no simple symmetries can be assumed: a 3D approach is then mandatory. The operating wavelength is comparable with cavity length ($\lambda_{RF}\sim L_{c}$), hence the ``resonator'' effect of the metallic cylindrical cavity where the plasma itself is sustained by the microwaves cannot be neglected. In addition, the characteristic lengths of plasma parameters are often smaller than the wavelength, thus implying a full-wave approach in modeling and simulations. These plasmas have to be described by lossy spatially dispersive ``hot'' ($v_\phi\sim v_{th}$) dielectric tensor in order to model the inner plasma modes conversion and plasma-waves. The paper describes in details the modeling strategy for both microwave-to-plasma coupling schemes and for advanced, microwave based diagnostics tools such as interferometry and polarimetry.

REGULAR SESSION PAPERS NVIS communication solutions are known to be reliable and quickly deployable, but modeling a suitable radio link requires a good prediction of the ionosphere behavior and insights regarding ionospheric propagation. Within the framework of the SIRIUS project, the Technical University of Cluj-Napoca has acquired, installed, and employed the NovAtel GPStation-6 GNSS receiver for ionospheric scintillation and TEC monitoring. The measured parameters are to be used in the development of ionospheric propagation models for HF transmissions in Eastern Europe. This paper presents the GNSS receiver and its employment for monitoring radio wave propagation through the ionosphere, as well as measuring the electronic density.
