Abstract
Wireless body area networks (WBANs) have received a great deal of attention for medical and health care applications. In order to monitor the bio-signals, it is necessary to ensure the robust communication links among the WBAN devices; the implantable device (in-body) to the wearable device (on-body), the wearable device to the wearable device, and the wearable device to the monitoring device (off-body) communications.
In this invited talk, three types of on-body antennas for bio–signal monitoring systems will be presented. 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.
With the fast advent of the aged society, the market for bio-signal monitoring systems is consistently expanding. Since an on-body antenna (wearable antenna) is one of the key components and plays an important role in establishing the successful communication channel for bio-signal monitoring systems, the proper design of on-body antennas considering practical applicability becomes very important issue.
