SAR impact evaluation on jeans wearable antennas

This paper addresses the effects of two main microstrip wearable antennas on the specific absorption rate (SAR) on the human trunk as well as their impact performance in terms of gain, efficiency and required area. Rectangular patch and PIFA jeans wearable antennas intended for wireless body area network applications at 2.45 GHz are under analysis. The SAR values averaged over 1 g and 10 g tissue of a realistic voxel model are computed according to the IEEE/IEC 62704-1 standard. The results are compared with the limits of exposure determined by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and the IEEE C95.1.
