Abstract
Disclosed is a wireless energy transmission structure which includes a disc part including a first conductor plate and a second conductor plate which are spaced to face each other and a dielectric material inserted between the first conductor plate and the second conductor plate, and generating an electric field between the first conductor plate and the second conductor plate; and a ring-shaped wire part one end of which is connected to the first conductor plate and the other end of which is connected to the second conductor plate, and having a meta structure in which a plurality of meta cells is repetitively arranged so as to induce a magnetic field using the electric field, so that the wireless energy transmission structure is reduced in size and is improved in transmission distance and transmission efficiency.
