A novel wireless power transmission system using microstrip coil structure with ferrite and dielectric layers

摘要

In this paper, a novel wireless power transmission (WPT) system composed of microstrip coils with ferrite and dielectric layers is proposed. The structure of each microstrip coil includes a loop one placed outside and a spiral one put inside. It would be concluded that the transfer efficiency of the proposed WPT system with load of 50 Ohm can get up to around 59.7% at the resonant frequency of 13.56 MHz.
