Claim 12:
13. An antenna apparatus comprising:
a dielectric layer;
a polygonal shape patch antenna pattern disposed on an upper surface of the dielectric layer;
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;
feed patterns respectively electrically connected to an upper end of a corresponding feed via, respectively disposed to be spaced apart from the patch antenna pattern, and configured to provide a feed path to the patch antenna pattern;
extended patch antenna patterns respectively disposed to be spaced apart from the feed patterns, respectively disposed to be biased toward the first side and the second side from the center of the polygonal shape of the patch antenna pattern, respectively disposed to be spaced apart from the patch antenna pattern, and having a side oblique to a side of a ground plane in a top view; and
first dummy patterns respectively arranged three-dimensionally between the plurality of feed patterns and comprising a plurality of patterns overlapping in a vertical direction.
