The radiation characteristics of two embroidered wideband wearable slot antennas covering 3.1-10.6 GHz: Ultra Wide Band (UWB) with different yarn-spacing densities have been presented and compared with a same-size reference copper antenna. When a wearable antenna is fabricated by a conductive yarn, it is important to assess the level of loss in respect to the yarn-spacing density [yarns/mm]. Therefore,...
In order to evaluate specific absorption rate (SAR) of human exposure in vicinity of wireless power transfer (WPT) devices operating in intermediate-frequency band, we have developed a human-equivalent dielectric liquid phantom using a diluted solution with the 0.04 mol/l concentrations. The liquid phantom has the same conductivity and indicates similar EM characteristics with two-third of the muscle...
