Analysis of SAR Caused by PIFA Mounted on Folder type MobileJ.D.Park, B.C.Kim, H.D.ChoiAnalysis of SAR Caused by PIFA Mounted on Folder type Mobile Phones*J.D.Park, B.C.Kim, H.D.ChoiRadio & Broadcasting Technology Laboratory, ETRI 161 Gajong-Dong, Yusong-Gu, Daejon 305-350, Korea  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……
