Abstract

This paper presents a small-size, dual-band implantable loop antenna operating in the medical implant communications service (MICS) band (402-405 MHz) and the Industrial, Scientific and Medical service (ISM) band (902-928 MHz). Biocompatible material of SU8 is employed in coating since the antenna is designed to work in human body. By using the meandering strategy, the size of the proposed antenna can be significantly miniaturized compared with the state-of-art ones at the operating bands (radius of 5.5 mm and height of 0.645 mm). The simulated bandwidths are 105% and 20% in MICS and ISM bands, respectively. The SAR and total efficiency are also simulated in CST human model and show excellent performances.
