Abstract

This work designs a compact implantable antenna for Bio-device in medical implant communication services band (MICS band: 402-405 MHz). The proposed antenna is a modification of Planar Inverted-F Antenna (PIFA), consisting of three layers, i.e., ground, lower patch, and upper patch. The stacked structure, with a thickness of 1.27 mm, extends the current path effectively, miniaturizing the antenna dimensions. To avoid injuring tissues in the human body, the antenna is made in the shape of coin with a radius of 4.5 mm. Considering real implantation cases, biocompatible film of parylene-C is employed to cover the implanted antenna isolated from the biological tissue. The antenna is simulated in a three-layer human tissue model and shows a good resonant performance.
