Abstract: PURPOSE: A wireless power transmission device and method for reducing radiated power of a magnetic resonator are provided to transmit energy by selecting a frequency having relatively low radiated power. CONSTITUTION: A signal generator(102) generates a frequency signal used for wireless energy transmission from general commercial AC powder. A power amplifying unit(104) amplifies the frequency signal. A signal detection unit(106) transfers the amplified signal to a magnetic resonator for wireless energy transmission and detects a radiated signal caused by the magnetic resonator. A standing-wave ratio calculation unit(108) calculates a standing-wave ratio from the detected signal. A control unit selects the frequency having the lowest standing-wave ratio using the standing-wave ratios calculated by the standing-wave ratio calculation unit.
