A kind of radio transmission technology based on positioning of the electromagnetic coupling array is presented in this paper. The research and development of the equipment is completed on this basis. Through the coupling detection of electromagnetic coupling array coil and receiver coil by MCU, it can only power to the coil with highest coupling, so that it always has a sending coil and receiving coils of electrical equipment, no matter what direction it is in, close to full coupling. In this way, it can avoid wasting energy, reduce the electromagnetic radiation, and particularly, realize tha...
