Abstract
A wireless power transmission apparatus includes: a transmission resonator installed in one side wall within a specific space and configured to comprise a transmission feeding loop for transmitting impedance matching and power and receive and transmit the impedance matching and power using the transmission feeding loop. Further, the wireless power transmission apparatus includes a relay resonator installed in another side wall within the specific space and configured to have a resonant frequency identical with that of the transmission resonator and store energy in the specific space by generating mutual resonance through a resonance characteristic with the transmission resonator; and one or more reception resonators installed within the specific space and configured to have a resonant frequency identical with that of the transmission resonator and receive the energy stored in the specific space.
