Experimental tests of SAR reduction on mobile phone using EBG structures

Sang Il Kwak, Dong‐Uk Sim, Jong Hwa Kwon, Hyung‐Do Choi

Abstract

Experimental tests of specific absorption rate (SAR) reduction on a mobile phone have been performed. To protect a human head from exposure to electromagnetic fields and comply with exposure guidelines, the electromagnetic bandgap (EBG) structures are inserted in a commercial personal communication services (PCS) mobile phone. The measured results demonstrate the movement of a hot spot and the reduction of SAR in the human head.
