1. A direct feeding apparatus for impedance matching of a wireless power transmission device, comprising:
- a helical type resonator formed of a conductive line; and
a feeding unit formed on the helical type resonator, the feeding unit being configured to directly feed power to an outside region of the helical type resonator having a relatively small current value as compared to a center of the conductive line of the resonator without the impedance matching,wherein, when the power by the direct feeding apparatus is directly fed to a transmitting device, the transmitting device provides the power to a receiving device in a resonance type wireless power transmission scheme, without the impedance matching.
