radiation performance

A parametric microstrip patch antenna is designed inside a homogeneous spherical eyeball model in order to take into consideration mismatching caused by surrounding tissues. Biocompatible encapsulation is achieved by using Zirconia (εr = 29, tanδ~0). 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.
