Abstract
Provided is an apparatus that may control a direction of wireless power transmission. A radiative wireless power transmitter may include at least two first unit resonators to form a magnetic field with a target resonator based on an x-axis direction and a z-axis direction, and to transmit a resonance power to the target resonator, at least two second unit resonators to form a magnetic field with the target resonator based on the x-axis direction and a y-axis direction, and to transmit a resonance power to the target resonator, at least two third unit resonators to form a magnetic field with the target resonator based on the y-axis direction and the z-axis direction, and to transmit a resonance power to the target resonator, and a feeding unit to control resonance power transmission of the at least two first unit resonators, the at least two second unit resonators, and the at least two third unit resonators.
