A flexible wideband wearable CPW antenna for WBAN application

Abstract This article presents a wideband wearable antenna with flexible substrate for Body Area Network application. The designed coplanar antenna has a return loss bandwidth of 3.5 GHz ranging from 5.15 GHz to 8.65 GHz with maximum return loss at 5.8 GHz (45.9 dB) and 7.4 GHz (31.4 dB). The average gain of the antenna is 4.069 dB. The obtained specific absorption rate of the antenna is below the FCC reference limit of 1.6 W/Kg per 1 g of tissue, making it suitable for biomedical application.
