Abstract: | In this work, we use Split Ring Resonator (SRR) in order to reduce the Radio Frequency (RF) radiations that are being absorbed in human head while using the cell phone. The Specific Absorption Rate (SAR) in the head can be reduced by placing the SRR between the antenna and head. The antenna performances and radiation pattern with metamaterials are analyzed. A comparative study with other SAR reduction techniques is also provided. We design periodic arrangement of Split Ring Resonators or specifically SWASSRR (SWAstika Shaped SRR). Local SAR can be reduced up to 57% by properly choosing the structural parameters at 900 MHz, 1800 MHz (GSM) and 2100 MHz (3G) bands. These results can provide helpful information in designing the mobile communication equipments for safety compliance. SAR reduced by creating a stop band or resonance near the operating frequencies. |
