Design of high gain circular patch antenna for bio-implants

Bio-Implants play a vital role in providing the regular functionality to the damaged or failure body parts of the patients. Nowadays wireless powering of implants is developed with various new techniques. The major components for proper and continuous powering of implants are biocompatible antennas. This work provides a circular shaped patch structured receiving antenna applicable for bio-implants which enhances the performance in terms of efficiency and gain. Here the size of the antenna gets reduced as of (8x0.56) mm2. The proposed antenna could be simulated with the operating frequency of 2.404GHz band to meet the gain level of almost-10dBi.
