Small planar monopole UWB wearable antenna with low SAR

This paper reports an overview of UWB jeans antenna and evaluates the safety limits by indicating the computed Specific Absorption Rate (SAR). Simple geometry of the design was aimed in order to fabricate the antenna with minimum errors. The proposed design is a rectangular patch placed on 32 × 34 mm² jeans substrate with partial ground. Simulated and measured S11 parameter for the antenna at free space is reported in this paper. Simulated radiation patterns are also presented in this paper. The performance of the antenna has then been examined in close proximity to a developed model of human arm. Evaluation of SAR has included calculating 10-g SAR when the antenna placed at 5, 10, 15 and 20 mm far from the phantom.
