Performance of a novel miniature antenna implanted in the human head for wireless biotelemetry

In this study, we present a novel, miniaturized, biocompatible antenna at the medical implant communications service (MICS) band (402-405 MHz) for integration in wireless biotelemetry devices implanted in the human head. To reduce simulation time, the antenna is designed while in the center of a skin tissue simulating box and subsequently implanted inside the skin tissue of an anatomical human head model. The resonance, radiation and specific absorption rate (SAR) performance of the antenna is evaluated and design modifications are suggested to overcome the inherent detuning effect.
