SAR evaluation of ultra wideband (UWB) textile antennas

This work presents a systematic investigation of the Specific Absorption Rate (SAR) of two ultra wideband (UWB) textile antennas. These popular UWB topologies are implemented using similar materials and evaluated at a common frequency point for comparison purposes in a certified SAR facility. Evaluations indicate that the antenna ground plane area and the distance to the body phantom also seriously affects SAR levels. This evaluation has also quantified the SAR measurement repeatability at various distances at a maximum of 10 %.
