In this paper, a novel miniaturized implantable circular PIFA antenna is presented. It supports both wireless information communication and wireless energy transmission at the Medical Device Radiocommunication band (MedRadio 402-405MHz) and the Industrial, Scientific and Medical bands (ISM 902.8-928 MHz). Antenna is circular to avoid sharp edges while miniaturization is achieved by adding two circular slots to the patch. Main scenario includes embedding into the muscle layer of a cylindrical three-layer model of a human arm for which several parameters are analyzed (resonance, radiation pattern and Special Absorption rate (SAR)). Power transmission efficiency and interaction distance limits to ensure connection are also evaluated. Index Terms-Implantable antenna, planar inverted-F antenna, wireless power transmission, industrial, scientific and medical (ISM) band, Medical Device Radiocommunications (MedRadio) band.
