Evaluation of Specific Absorption Rate (SAR) Reduction for PIFA antenna Using Metamaterials

This paper is analyzed the reduction of specific absorption rate (SAR) with metamaterials attachment. The SAR reduction methodology is discussed and the effects of attaching location, distance, and size of metamaterials, on the SAR reduction are explored. Metamaterials have achieved a 57.75 % reduction of the initial SAR value for the case of 10 gm SAR. Index Terms – antenna, human head model, lossy-Drude model, metamaterials, specific absorption rate (SAR).
