Meta surface enabled wearable antenna for medical implant applications

Abstract

We proposed a metasurface enabled antenna that operates in the frequency ranges from 2.36GHz to 2.4GHz. The monopole antenna placed on an array of two I shaped anisotropic surface, the metasurface act as the ground plane as well as the main radiator. The antenna is exclusively for medical sensing and monitoring applications. The proposed antenna shows better improvement in terms of gain and radiation than that of conventional antenna. The proposed antenna will provide a gain of about 6 db. And will provide 5.5% of impedance bandwidth. The specific absorption rate also can be reduced about 95.3 % by implanting the antenna on metasurface which shows good improvement than that of conventional antennas.
