    Abstract: The present invention relates to a Yagi antenna and a wireless power transmission apparatus comprising the same, and the Yagi antenna includes a wireless power transmitting coil and first and second slabs made of a metamaterial having a CHDR structure in which cube-shaped resonators are arranged at a predetermined interval. The first slab is positioned at a rear side of the power transmitting coil and serves as a reflector that reflects an electromagnetic wave generated at the power transmitting coil, and the second slab is positioned between the power transmitting coil and a power receiving coil and serves as a super lens that focuses the electromagnetic wave generated at the power transmitting coil. The wireless power transmission apparatus improves efficiency of wireless power transmitted to the power receiving coil by using the Yagi antenna.
