摘要

A compact monopole antenna backed with a 1 × 2 textile-based artificial magnetic conductor(AMC) array is proposed. Textile was mainly selected for the AMC materials according to aninvestigation that took place between different AMC substrate materials, where it was settledthat the textile one displayed the highest antenna gain and efficiency. The monopole antennaand the AMC, distanced apart by 5 mm, combined form the integrated design. It operates at2.4 GHz, which was particularly selected as the resonant frequency for wirelessly sending thesubject’s symptoms data via Wi-Fi, with realized gain and total efficiency of 6.76 dBi and88.4%, respectively, in free space. Separated by 3mm from the specific anthropomorphicmannequin human hand model, it displays a realized gain and total efficiency of 4.06 dBiand 44.39%, respectively, in a flat condition. Furthermore, it exhibits a specific absorptionrate (SAR) of 1.8 W/kg averaged over 10 g of tissue. When bent over the human handmodel, it performs well and exhibits a maximum SAR of 0.521 and 0.406 W/kg, averagedover 1 and 10 g of tissues, respectively. As a result of such outcomes, the proposed integrateddesign can be nominated for wearable hand/wrist and Wi-Fi applications.
