Abstract

This project is focused on the study of the antenna parameters and the radiation effect in the human arm model produced by the implantable flexible hexagonal shape patch antenna. This implantable hexagonal shape patch antenna is flexible and suitable for wearable applications. The special feature of this antenna is it is flexible and wearable to any part of human arm body which operates at 402 - 405 MHz MICS (Medical Implant Communication Service) on the optimization of the chosen implantable antenna for bandwidth return loss, radiation which shows the efficiency of the proposed antenna. This flexible hexagonal shape patch antenna is measured in two different phantom tissues inside human arm model which are fat and muscle are presented in this paper. There are two conditions of observation which are antenna in free space condition and attach to human arm model condition. Both conditions were analyzed, in term of antenna performance such as frequency, return loss, realized gain, directivity, and efficiency. After that, the simulation is carried out in the proximity inside human arm model which commensurate with the antenna field region and the size of antenna's reactive near-field that is satisfied to be an important factor in the evaluation of an acceptable in body operation. For the implanted hexagonal shape patch antenna in muscle layer, the resonant frequency is 403 MHz and the return loss is -33.937dB. The realized gain is 0.91.The maximum 1.6 W/kg SAR is 1.52 for 1g of tissues. Therefore, those parameters are satisfied. The results of this study are helpful to engineers and doctors evaluating antennas for the use of flexible hexagon patch antenna in medical application. More specifically, this work focuses on antennas to be integrated into implantable devices with far-field data telemetry capabilities.
