Abstract

In this paper, specific absorption rate (SAR) reduction at the PIFA type for a mobile phone using various types of EBG structure are tested. Two EBG structures, that is a via or a via-less, are designed. The EBG structures can reduce the surface wave and prevent the undesired radiation from the ground plane. Thus, the EBG structure which is designed for mobile terminal enables to comply with the exposure guideline. From the simulation and measured results demonstrated the reduction of the radiation pattern towards the direction of human head and the SAR value.
