Performance analysis of a planar inverted-F antenna (PIFA) including human interaction

In the rapid progress of commercial communication applications the development of small integrated antenna has an important role. Planar inverted-F antennas (PIFAs) are commonly used as handset antennas. This paper presents the analysis on the performance of single band PIFA antenna for handsets. Different specifications of the proposed antenna are measured through computer simulation in free space as well as in the presence of human head model. The Specific Absorption Rate (SAR) is also measured for this antenna and how the antenna interacts with human body that is also observed. All simulation results are performed using the CST Microwave Studio.
