Abstract
Provided is a millimeter wave band patch antenna. The patch antenna includes a multi-layer substrate, at least one metal pattern layer, an antenna patch, a ground layer, and a plurality of vias. In the multi-layer substrate, a plurality of dielectric layers are stacked. The metal pattern layer is disposed between the dielectric layers except for a center region of the multi-layer substrate. The antenna patch is disposed on an upper surface of the multi-layer substrate in the center region. The ground layer is disposed on a lower surface of the multi-layer substrate opposing to the upper surface. The vias is disposed around the center region through the dielectric layers for electrically connecting the metal pattern layer to the ground layer. The center region, which is surrounded by the ground layer and the vias, functions as a resonator.
