The aim of this paper is to review various techniques smeared in the last decade for the elevation of low Specific Absorption Rate (SAR) of cellular phone using auxiliary antenna elements. Considering health hazards of EM radiation from mobile phone, it is discernible that a mobile phone antenna must have low SAR characteristics which can be achieved by imposing SAR reduction methods. There are some abridgments for every reduction technique which restrain the extensive use of available mobile phone considering bandwidth, efficiency, size, cost and easy implementation. Among all of SAR reduction methods metamaterial technique may be more satisfying considering all aspects. Along with, we can consider SAR affecting parameters and make optimization for better response.
