Commercial plaster material (polyacrylate) is used as an antenna substrate. Two 2.45 GHz patch antennas are introduced, both designed to be attached directly to the skin. Measured efficiencies are 70 % in free space and 60 % on-body. Measured on-body gains of each antenna are 6.2 and 1.4 dBi. Simulated 1 g specific absorption rates (SAR) of the two antennas are 2.3 W/kg and 1.6 W/kg using 1 W input power. 10 g SAR values are 0.6 W/kg and 1.2 W/kg. Antenna feeding using snap-on buttons is… CONTINUE READING
