Designed a small power strong magnetic coupling resonance can radio transmission system. The system consists of high frequency inverter circuit ,resonance coupling module, and high-frequency rectifier filter modules. Transmitter coil and receive coil under the fixed frequency of 1 MHz resonance, since the spacing can be 1 m within the scope of the load power. Experimental analysis, the electromagnetic coupling resonance can radio transmission, the system energy between the two resonant coil changes over time, radio transmission distance and signal frequency and related parameters on the effi?ciency of the power and influence.
