Abstract

An implantable, compact, planar inverted F-antenna (PIFA), designed for a wireless telemetry system operating in the Australian 900MHz ISM band (915-928 MHz), is described in this paper. The antenna has been designed to operate well when it is positioned inside the body of a rat. The overall dimensions of the antenna are 12×12×4mm³. The predicted bandwidth of the antenna is found to be 8.5% (from 880 MHz to 960 MHz) at 10dB return loss. The sensitivity of antenna impedance matching to variations in the rat´s body material is investigated. It is found that the antenna should operate well in the ISM band even when the body tissue parameters change within a significant range.
