1. A system for reducing a radiation field in a wireless power transmission system, the system comprising:

  • a signal generation unit configured to receive power and generate a signal for wireless power transmission;

    a power amplification unit configured to amplify the wireless signal generated by the signal generation unit;

    a signal detection unit configured to detect a radiation signal generated by the magnetic resonator with respect to output power of the power amplification unit;

    a standing wave ratio (SWR) calculation unit configured to calculate an SWR using the detected radiation signal; and

    a control unit configured to select a frequency having a lowest SWR based on the SWR calculated by the SWR calculation unit, and control the signal generation unit to generate the signal for the wireless power transmission using the selected frequency.
