SAR Analysis of Antenna Implanted Inside Homogeneous Human Tissue Phantom

In this paper, specific absorption rate (SAR) field of planer inverted F antenna (PIFA) inside the numerical homogeneous human muscle phantom model is investigated. Two antennas; meander PIFA and wrinkle PIFA are implanted and simulated to resonate at 2.4 GHz. The size of the proposed design is 25 × 22.4 mm on 20mil thick Rogers RT/ duroid 5880 substrate. The proposed design claims ultra wide band property with more than 1.5 GHz bandwidth. The SAR value of different simulating human tissue is obtained up to 30 mm away from antenna. The maximum average SAR value of antenna inside human muscle tissue is obtained to be 0.87W/kg and 2.1W/kg at 1mm distance from antenna plane. The design conveys quite good gain inside conducting lossy tissue comes to be −21.57 dB and −22.3dB.
