A wireless power transmission device, a wireless power transmission control device, and a wireless power transmission method are provided. A coupling frequency between a source resonator and a target resonator is determined. A transmission frequency is controlled such that power is transmitted from the source resonator to the target resonator at the coupling frequency. Therefore, it is possible to maintain a high power transmission efficiency without using an additional matching circuit even when a distance between the source resonator and the target resonator is changed.

Wireless power transmission device, wireless power transmission control device, and wireless power transmission method

The present invention relates to a system for transferring wireless power or signal. The system includes a first antenna; and a second antenna which is located from the first antenna at an arbitrary distance and arranged in an arbitrary direction in comparison with the first antenna, wherein respective spherical modes of the first antenna and the second antenna are allowed to have orders which are same as or larger than a predetermined value to thereby transfer wireless power between the first antenna and the second antenna.

Method, system and computer-readable recording medium for transferring wireless power by using antennas with high orders of spherical modes
