Abstract
A J-shaped proximity coupled Planar Inverted F-Antenna (PIFA), designed to be implanted into rat's body, is presented in this paper. The operating frequency range of the antenna is the Australian ISM (915-928 MHz) band. Antenna's surrounding (rat's body tissue) model has been developed and applied in the simulation to study the antenna radiation patterns, return loss and impedance bandwidth. The proposed multilayer PIFA antenna is compact and its dimensions are 13.5 mm × 11 mm × 4.25 mm including the ground plane. The antenna is designed to be connected with the RF module of a Radio Frequency Identification (RFID) circuit board. The wireless link distance between the implantable RFID device and external base station is approximately 2m. A 5% impedance bandwidth at 10dB return-loss is predicted.
