Abstract

This paper proposes a multiband handset antenna combining PIFA and novel slots on a radiating patch of PIFA for mobile applications. Two slots were introduced in order to embody 900 and 1800 MHz band. Radiation patterns are computed in free space as well as in the presence of the head. Specific Absorption Rate (SAR) of the slotted PIFA antenna is calculated and is compared with the SAR limits in the safety standards. SAR is investigated, by discussing the effect of RF shield which is introduced between the slotted PIFA antenna and head. Simulation results show that with the introduction of the RF shield of thickness of 1mm, SAR reduces by 12%. All simulations are done in FEKO software.
