摘要: In this paper, a novel miniaturized implantable circular antenna is presented. It supports both wireless information communication and energy transmission at the Medical Device Radiocommunication band (MedRadio 402–405 MHz) industrial, scientific, medical bands (ISM 902.8–928 MHz). The to avoid sharp edges while miniaturization achieved by adding two slots patch. main scenario includes embedding into muscle layer of cylindrical three-layer model human arm for which several parameters are analyzed (resonance, radiation pattern, specific absorption rate). Power efficiency interaction distance limits ensure connections also evaluated. Finally, design validated an experimental measurement in anechoic chamber, some new improvements proposed.
