Abstract：The simultaneous transmission of wireless power and wireless information is a hotspot of wireless charging system. Based on the single coil and dual band resonant structure, system model has been constructed. The formulas of Q value in energy transmission frequency, the bandwidth value of signal transmission frequency and the crosstalk between the energy and signal transmission channel have been deduced. From the view of balancing the transmission power performance and signal transmission rate, the design methods for circuit parameters were analyzed. Finally, simulation models and experimental platform were set up to verify the proposed circuit design method.
