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

Abstract

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.

Designs of rectangular-shaped planar Inverted-F antennas at mobile operating frequencies with different ground plane techniques

“…Currently, wireless devices become essential in connecting plentiful users at anytime and anywhere, which require a low profile antenna. Planar inverted-F antenna (PIFA) can be categorized as one of the lowest profile antennas that used widely in a handheld wireless device that has several advantages of simple structure, small size, easy to fabricate and low manufacturing cost [1][2][3][4]. Furthermore, PIFA gives a smaller size compared to rod, monopole and helix antenna, which lead to easier locating and alignment between the components [4].…”
