Design of Implanted PIFA for Implantable Biotelemetry Locations: Chest and Abdomen

This paper presents a planar inverted-F antenna (PIFA) worked for implanted biotelemetry medical devices such as cardiac pacemaker. The implantable antenna operates in the 403.5 MHz, MICS band. Two commonly implanted locations, the upper chest and the center of abdomen, are selected to evaluate the antenna performances. The specific absorption rate (SAR) and radiation characteristics have been studied to determine the effect on the human tissue. The distances between an implanted antenna and the skin have been studied. The PIFA are implanted first in the three-layer phantom and then the realistic man model later. The comparative results of simulations and measurements are analyzed and presented in this study.
