Abstract: Disclosed is a dielectric resonator antenna. The dielectric resonator antenna includes: a dielectric resonator; an antenna layer formed inside the dielectric resonator, and including a plurality of vias positioned at a surrounding area of the dielectric resonator; a metal pattern forming an opened surface in an upper portion of the antenna layer; a dielectric layer configured to cover the metal pattern on the dielectric resonator; an internal ground pattern including a coupling aperture for inputting a signal into the dielectric resonator under the dielectric resonator; and a feeding layer including a strip transmission line for transmitting a signal to the dielectric resonator, and positioned under the antenna layer.
