Abstract :
A design of planar rectangular spiral antennas for the wireless vehicle battery charging system operating at 13.56 MHz is presented in this paper. The proposed antennas are designed with low-cost, low-complexity and low-profile constraints. The study is performed by analyzing the power transmission efficiency of the spiral antennas via scattering parameters and associated reflection coefficients. Moreover, the misalignment between the transmitting and receiving antennas and effects of a car structure on the power transmission efficiency are investigated. It is found that the misalignment and the car structure strongly affect the power transmission efficiency.
