Abstract
A wearable fabric CPW antenna is presented for medical body area network (MBAN) applications at 2.4 GHz based on an electromagnetic bandgap design and frequency selective surface (EBG-FSS). Without EBG-FSS, the basic antenna has an omnidirectional radiation pattern, and when operated close to human tissue, the performance and efficiency degrade, and there is a high specific absorption rate. To overcome this problem, the antenna incorporates EBG-FSS, which reduces the backward radiation, with SAR reduced by 95%. The gain is improved to 6.55 dBi and the front-to-back ratio is enhanced by 13 dB compared to the basic antenna. The overall dimensions of the integrated design are $60\times 60\times2.4$ mm3. Simulation and experimental studies reveal that the antenna integrated with EBG-FSS can tolerate loading by human tissue as well as bending. Thus, the design is a good candidate for MBAN applications.
Highlights
Medical Body Area Networks (MBAN) are becoming a vital technology in wearable systems, with applications in telemetry and medicinal services
The antenna and electromagnetic band-gap design and frequency selective surface (EBG-frequency selective surface (FSS)) are designed based on fabric materials that can be integrated with our daily clothes
The results show that when an antenna on its own, without electromagnetic band-gap (EBG)-FSS, is loaded by human tissue, the frequency detunes: the antenna performs poorly because of the lossy human tissues
Summary
Medical Body Area Networks (MBAN) are becoming a vital technology in wearable systems, with applications in telemetry and medicinal services. The performance of the MBAN relies on the efficiency of the wireless communication devices, which need to be light-weight, low-profile, miniaturized, efficient, flexibly conforming to the shape of the human body, and capable of giving continuous monitoring. The HIS designs attain high degrees of isolation between the antennas and the body tissues These proposed designs have the drawbacks of large footprints and may be too thick and big for MBAN applications [27,28,29,30,31,32,33], use semi-flexible material that is not adequately bendable and may not be comfortable for users [34, 35].
