Ground plane effects on SAR for human head model exposed to a dual-band PIFA

Effects of ground plane on the Specific absorption rate (SAR) in SAM head model exposed PIFA antenna is investigated in this paper. The dual-band PIFA working at 900M and 1800M is designed to operate with a ground plane, and the ground plane is an integral part of the antenna assembly. To investigate systematic biases on SAR in SAM head model resulting from shape effect of the ground, both the average SAR over a mass of 1g and 10g in the head models exposed to a dual band PIFA were determined. These results are very useful in the design of a PIFA for applications requiring a small ground plane.
