Abstract
AbstractThe design of portable textile‐based asymmetric coplanar strip‐fed comb‐shaped patch (CSP) antenna is proposed and analyzed for Medical Body Area Network and Industrial Scientific and Medical band applications. A thin sheet of fabric with high conductivity has been embedded on a denim textile to fabricate a flexible conductive wearable antenna. The CSP antenna is validated in both free spaces and on the body. The proposed CSP antenna resonates at an operating frequency of 2.49 GHz (2.27–3.42 GHz) for free space with a bandwidth of 1150 MHz. On‐body, the antenna resonates at 2.44 GHz (1.9–2.8 GHz) with a bandwidth of 900 MHz. The gain is 4.67 dBi for free space, and −4.82 dBi for on‐body is observed. The CSP antenna was tested under bent and crumpling conditions, and the performance remains unaffected by the deformation. The CSP antenna performance is analyzed by using the artificial human hand for the physically challenged people. Specific absorption rate is 1.4 W/kg, and values under the electromagnetic radiation exposure limits have been obtained, with a safe margin of 1.6 W/kg. There is good agreement between the simulation and measurement results for the proposed CSP antenna.
