Wearable Small, Narrow Band Highly Efficient, Compact Conformal, Low-Profile Metasurface Antenna For Medical Devices

Ashraf Sayed Abdel Halim

In this research, I suggest a compact orthomorphic wearable antenna that works in the 2.36-2.4 GHz medical body-area network band. The antenna is implemented by installing a highly truncated metasurface, composed of only a 2 2 array of Ishaped ingredients, beneath a planar monopole. In contradiction to formerly described artificial magnetic conducting ground plane backed antenna plans, in this study, the metasurface acts as a ground plane for isolation, as well as the principal radiator. An antenna prototype was manufactured and examined, illustrating a powerful compromise between simulation and measurement. Comparing to formerly suggested wearable antennas, the validated antenna has a compact form factor of 0.5λ0 , 0.3λ0 , 0.28λ0 all while achieving a 5.5% impedance bandwidth, a gain of 6.2 dBi, and a front-to-back ratio more than 23 dB. The more numerical and experimental analysis demonstrates that the act of the antenna is extremely potent to both structural distortion and human body loading, much better to both planar monopoles and microstrip patch antennas. Furthermore, the introduced metal backed metasurface let a 95.3% decrease in the specific absorption rate, producing such an antenna a prime candidate for establishment into many wearable devices.
