Abstract
In order to improve the transmission efficiency of magnetic coupling resonance for wireless transmission technology, the dual coil wireless transmission system was designed and simulated based on ANSYS. Influencing factors of transmission efficiency include coil turns, material properties, frequency characteristics, and maximum transmission distance. A relevant experimental circuit is designed to verify the correctness of the theoretical analysis and provide an effective reference to improve the efficiency of radio energy transmission. Through the analysis of past improvement schemes, the performance of wireless transmission equipment is optimised based on electromagnetic field simulation and the frequency-splitting phenomenon is verified.
