SAR Evaluation of Flexible UWB Antenna for Wearable Applications

Abstract

Abstract This manuscript appearance a compact and Ultra-Wideband (UWB) antenna for wearable applications. The proposed coplanar waveguide (CPW) feed circular configuration patch antenna is simulated on two different dielectric materials one flexible polyamide based Cordura fabric and other is FR-4, with small footprint of size 36 × 46 mm2. The antenna works in complete UWB band from 3.1 to 10.6 GHz. The performance of the antenna was examined in free space and three-layer human body phantom. This research work also presents the flexibility analysis of structure for both substrates. These examinations exhibited that proposed UWB antenna is an appropriate contender for wireless body area network (WBAN) operation.
