Abstract

In this paper, the radiation mechanism of an implanted planar inverted F antenna (PIFA) is studied to improve radiation performances of PIFA in a human body by changing the width of the planar radiators. The PIFA is designed to operate at the medical implant communications service (MICS) frequency band (402-405 MHz). The numerical computational procedures (Annex E of Std. C95.3-2002) recommended by IEEE are applied to calculate spatial-average specific absorption rate (SAR) for the implanted antennas located in a biological tissue model. An experimental setup is used to measure the impedance matching characteristics of the implanted antenna
