An antenna apparatus includes a dielectric layer; a patch antenna pattern disposed on an upper surface of the dielectric layer and including an upper surface having a polygonal shape, a plurality of feed vias respectively disposed to penetrate the dielectric layer by at least a portion of a thickness of the dielectric layer, respectively disposed to be biased toward a first side and a second side, different from each other, from a center of the polygonal shape of the patch antenna pattern, and respectively disposed to be spaced apart from the patch antenna pattern, and a plurality of feed patterns respectively electrically connected to an upper end of a corresponding feed via, among the plurality of feed vias, respectively disposed to be spaced apart from the patch antenna pattern, and configured to provide a feed path to the patch antenna pattern, wherein the polygonal shape of the patch antenna pattern has a structure in which the first side and a third side between the first and second sides form an obtuse angle, and the third side and the second side form an obtuse angle.

Antenna apparatus

An antenna apparatus includes a ground plane, a patch antenna pattern disposed on an upper surface of the ground plane, a feed via penetrating the ground plane and spaced apart from the patch antenna pattern, and a coiled feed pattern electrically connected to an upper end of the feed via, spaced apart from the patch antenna pattern, and configured to provide a feed path to the patch antenna pattern, wherein at least a portion of the coiled feed pattern is coiled, wherein the patch antenna pattern includes an aperture portion corresponding to the coiled feed pattern.

An antenna apparatus includes a first patch antenna pattern comprising a through-hole, a second patch antenna pattern disposed above the first patch antenna pattern and spaced apart from the first patch antenna pattern, a first feed via electrically connected to the first patch antenna pattern, a second feed via penetrating through the through-hole of the first patch antenna pattern, and a feed pattern disposed between the first patch antenna pattern and the second patch antenna pattern, and having one end connected to the second feed via, and another end connected to the second patch antenna pattern at a point closer to an edge of the second patch antenna pattern than the second feed.

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.

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.
