PURPOSE: A wireless power transmission and reception system is provided to charge a plurality of target apparatuses by gradually transmitting wireless power using a plurality of resonant frequencies. CONSTITUTION: A detection unit(150) creates a wakeup signal which turns on a plurality of target apparatuses using AC(Alternative Current) power. The detection unit detects the plurality of target apparatuses based on a response signal for the wake-up signal. A control unit(120) determines a plurality of resonant frequencies matched between the detected target apparatuses. The control unit controls the plurality of the resonant frequencies for transmitting the AC power to the detected target apparatuses. A source resonant unit(130) successively transmits the AC power to the detected target apparatuses using a magnetic coupling force between the source resonant apparatus and the target resonant apparatus.
