Abstract

In recent years, planar inverted F antennas (PIFAs) are attractive candidates for using in mobile phones due to
its ability to reduce SAR induced in the human head and its compact size. In this research, the PIFA is designed
to apply for a folder type mobile phone with small size enough to be inserted in a folder case and SAR on human
head is calculated. In the simulation, the case of the phone is composed of plastic materials (εr = 2.2). Apertures
(LCD, microphones, key pad, etc.) of the phone are also considered. The operating frequency is about 1.8 GHz.
The performances of the folder type mobile phones such as impedance bandwidth, gain and radiation patterns
were simulated using CST based upon FIT method. 1g-averaged peak SAR was simulated using SEMCAD
based upon FDTD method. From the results, SAR caused by PIFA mounted on the folder type handset is less
than that caused by helix of same condition.
