The present disclosure relates to an antenna apparatus, comprising: a first conductor plate disposed on a top surface of a single substrate and including an aperture; a plurality of vias inserted vertically through the single substrate; A second conductor plate disposed on a lower surface of the single substrate, and a dielectric resonator embedded in a cavity formed by the first conductor plate, the second conductor plate, and the vias, And a feed line for applying a signal to be applied. Here, the opening surface has a size that generates multiple resonance at an operating frequency. |
