Abstract
An antenna apparatus includes a ground layer, patch antenna patterns, feed vias, ring-type meta patterns, and coupling-type meta patterns. The ground layer has one or more through-holes. Patch antenna patterns are each disposed above the ground layer. Feed vias are disposed to penetrate through the one or more through-holes, and electrically connect to the patch antenna patterns, respectively. Ring-type meta patterns are arranged between the patch antenna patterns. Coupling-type meta patterns are alternately arranged between the patch antenna patterns in fewer numbers than the ring-type meta patterns in positions more distant from the patch antenna patterns than positions in which the ring-type meta patterns are arranged.
