Wearable ultra-wideband half-disk antennas

We investigate the feasibility of ultra-wideband half-disk structures as wearable antennas for indoor and outdoor applications of ultra-wideband bodyworn devices (3.1-10.6 GHz). First, we characterize camouflage cloth in terms of relative permittivity and loss tangent. Then, based on the estimated substrate information, we design wearable half-disk antennas and compare the performance of solid copper and woven versions in the frequency and time domains.
