Abstract :
A new concept for mobile wireless power transmission is proposed based on a microwave directional coupler and directional filter. To cope with the uniform power transmission line required in the system, the circuit configuration should be changed keeping matching with the external circuits. Analysis and experiment is carried out to show the power acquisition from a uniform line with the coupling coefficient from -10 dB to 0 dB by making good use of the directional coupler scheme or directional filter scheme.
