Summary:
We propose a power recollecting circuit in wireless power transfer system using sheet-like waveguide. This circuit consists of a phase shifter with a small transmission loss and feedback loop of RF power to the source to improve the overall efficiency of the system. This paper shows this recollecting method and experimental results. In experiment, this circuit recollects 76% of waste power, and in ideally case, the value is 93%. Moreover, the power gain is up to 4.1dB at the waveguide input port.
