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.

Yagi antenna shaped wireless power transmission apparatus

Disclosed herein are a RF resonator, a RF coil, and a magnetic resonance imaging (MRI) apparatus. The RF resonator includes a dielectric substance which is provided, on one surface thereof, with an electric conductor, and at least one conductor line which is installed on another surface of the dielectric substance so as to face the electric conductor and provided with a plurality of open-cut portions which are disposed in a plurality of rows.

Radio frequency resonator, radio frequency coil and magnetic resonance imaging apparatus

The present disclosure relates to a radio frequency resonator and a magnetic resonance imaging apparatus comprising the same. A radio frequency resonator for a magnetic resonance imaging apparatus in accordance with the present disclosure comprises: a microstrip substrate; a conductive pattern portion for resonance that is formed on one surface of the microstrip substrate and increases an intensity of a magnetic field which is generated by resonating an RF signal; and a ground conductive board that is formed on the other surface of the microstrip substrate. According to the present disclosure, there is provided a radio frequency resonator for a magnetic resonance imaging apparatus capable of generating an intense magnetic field.
