In-Silico And In-Vitro Testing Of An Implantable Superstrate Loaded Biocompatible Antenna For Mics Band Applications

A superstrate loaded body implantable microstrip patch antenna working on Medical Implant Communications Service (MICS) (402-405 MHz) band for biotelemetry applications is proposed. A 0.64-mm thick high-dielectric material Rogers RO Duroid 3010 is used both as substrate and superstrate of dielectric constant 10.2. Shorting pin is used to make compact antenna with footprint of 13.3 x 14.6 mm(2). Appreciable bandwidth of 40% is covered by antenna with return loss of -30.95. In-silico testing inside skin, brain and three layered tissue models is done to test functionality of antenna in homogeneous as well as inhomogeneous tissue environment. For validation of results the fabricated antenna is successfully tested inside in-vitro solution of homogeneous skin mimicking liquid.
