Abstract

We analyzed the structural parameters of a guiding coil and a feeding loop for wireless power transfer in mid-range. The length, diameter, and number of turns of the guiding coil are the major factors to determine the resonant frequency. The separation distance between the coil and the loop also affects the power transfer ratio. This scheme has a greater transmission efficiency than using dipoles.
