摘要： 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.

摘要： An antenna apparatus may include: a feed line; a ground plane disposed around a portion of the feed line; a feed via electrically connected to the feed line; a first end-fire antenna pattern disposed in front of the ground plane to be spaced apart from the ground plane, and electrically connected to the feed via; a second end-fire antenna pattern electrically connected to the feed line and disposed farther forward than the first end-fire antenna pattern; and a third end-fire antenna pattern electrically connected to the feed via, and disposed in front of the first end-fire antenna pattern in such a manner that a portion of the third end-fire antenna pattern overlaps the second end-fire antenna pattern.
