Open-ring resonator coupling is used for the wireless power transmission through 1.6 mm thick epoxy-glass plate. Microwave signal is emitted from one circuit board where an open-ring resonator is placed and the signal is received by another board with also an open-ring resonator and GaN Schottky barrier diode. At 2.3 GHz, RF to DC conversion efficiency of 37.1% is obtained at the input power of 3.01 W and the output voltage of 8.75 V.
