Abstract
An apparatus for transmitting power wirelessly is provided. The apparatus comprises: a dielectric resonator which generates evanescent waves in a predetermined direction in order to transmit power; and a loop antenna which is coupled to a surface of the dielectric resonator and supplies power to the dielectric resonator. The dielectric resonator transmits power by means of evanescent waves generated in directions perpendicular to top and bottom surfaces of the dielectric resonator and by radiation in directions parallel to the top and bottom surfaces of the dielectric resonator. Accordingly, efficient power transmission over short and long distance ranges is possible.
