Abstract :
This paper presents a new resonance structure for high efficiency near-field coupling wireless power transfer. This design can be directly matched to the frontend circuitry without any extra matching components. The new coupler uses a single turn wide strip resonator, which has been proven has the best coupling efficiency, as a resonator. The full-wave simulation results shows 50% coupling efficiency for a distance three times larger than the diameter of the coupler.
