Abstract :
A miniaturized partially-folded planar inverted F-antenna (PF-PIFA) is proposed for a wireless physiological data acquisition system, being developed for small rodents including rats. The system operates in the Australian 900MHz ISM band (915-928 MHz). The overall size of the antenna is 26×19×4.4mm3 and it has been designed to be implanted just under the skin of a rat. The 10dB return-loss bandwidth of the antenna is 2.8%, which is sufficient for this telemetry system. The RF link distance between the implanted and external antennas is assumed to be less than 2m.
