Five-coil Wireless Charging Structure with Radiated Slots in UAVs for Mutual Inductance Reduction

This paper proposes an optimized scheme using radiated slots for the coupling structure. The proposed structure can reduce the coupling between the coils and improve charging efficiency in unmanned aerial vehicles (UAV). The coupling structure of four transmitting coils and a single receiving coil is designed and simulated by finite element method. The final results verify the correctness and feasibility of the scheme.
