Abstract This paper expounds the working principle of magnetic resonance radio energy transmission, and analyzes the system modeling from the point of view of the circuit. The maximum efficiency product is considered as the optimization function in view of the low efficiency of the magnetic resonance radio energy transmission system to meet the maximum output power. In view of the relationship between the parameters in the coil design process, an optimal design method of the PCB coil with limited size is proposed. Given the maximum efficiency product as the objective function, combining theoretical analysis and simulations, the optimal design of the PCB coil with size limitations is proposed. Finally, a group of coils are constructed based on the optimization results, whose mutual inductance and AC resistances are also tested experimentally. The tested results match well with the calculations and simulations, thus verifying the feasibility of the proposed optimizing method.
