2.4 GHz plaster antennas for health monitoring
conference contribution
posted on 2009-09-24, 11:38 authored by Tiiti Kellomaki, W.G. Whittow, Jouko Heikkinen, Lauri KettunenCommercial 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 investigated and has been found useful.
