A Miniaturized Wideband PIFA Antenna for Medical Implant Systems
By
Progress In Electromagnetics Research C, Vol. 166, 97-105, 2026
Abstract
This article presents a miniaturized wideband planar inverted-F antenna (PIFA) for deep biomedical implant applications at 915 MHz. Compactness and wide impedance bandwidth are achieved using a shorting pin, a circular radiating patch, and open-ended slots etched in the ground plane. The antenna occupies an ultra-small volume of 63.5 mm3 and is designed and analyzed inside a four-layer cylindrical human tissue phantom. Simulated and measured results show stable impedance matching over the ISM band, with a measured -10 dB bandwidth of 481 MHz (44.02%) and a peak realized gain of -28 dBi. Specific absorption rate (SAR) analysis confirms compliance with IEEE safety limits. In-vitro measurements using minced pork exhibit close agreement with simulations, validating the antenna's performance and suitability for reliable deep biomedical implant communication systems.
