Validation and safety performance of a biocompatible patch antenna for retinal prosthesis

A parametric microstrip patch antenna is designed inside a homogeneous spherical eyeball model in order to take into consideration mismatching caused by surrounding tissues. Safety and radiation performance studies for telemetry in the MedRadio band (401 -406 MHz) are carried out using the SEMCAD X suite, based on the finite difference time domain (FDTD) method.
