Simulation of Planar Inverted F Antenna for On-Body and free space Communication

Abstract

The expansion of recent wireless communications devices has put significant Compression on the antenna performance, as the size of the device has decreased in parallel to the increase in the number of communications systems supported by a single terminal. The Body Area Network (BAN) helps constant monitoring of Human health with updates of medical records through Internet. In this paper, we propose an on-body and free space performance of Planar Inverted F antenna which operates in Industrial scientific and Medical (ISM) frequency band at 2.45 GHz. The planar inverted –F antenna is popular for portable wireless devices because of its low profile, small size, and built-in structure This antenna is designed to achieve better Specific absorption rate. Other field parameters like Gain, Directivity, Return loss and Radiation have been evaluated on the body and on free space antenna with FEM based software HFSS ver. 13.0.
