Abstract

This paper proposes a novel low SAR multi-band PIFA structure with reduce exposure of the human head to mobile-set antenna radiation. Triple band PDA structure operating at GSM 900, GSM 1900 and Wi-Fi bands are designed and fabricated. Analysis of SAR is SAR is decreased by reducing the radiation towards human head, while maintain significant radiation in all other directions. This SAR reduction is accomplished by inserting suitable slots in the top radiating patch and ground plane of PDA at appropriate positions so as to modify the current distribution and radiation pattern.
