1. An antenna apparatus, comprising:
a patch antenna pattern;
a first feed via configured to feed power to the patch antenna pattern in a non-contact manner on a first side of the patch antenna pattern;
a second feed via configured to feed power to the patch antenna pattern in a non-contact manner on a second side of the patch antenna pattern;
a plurality of first feed patterns disposed on the first side of the patch antenna pattern on different levels and overlapping each other, and including at least one feed pattern that is electrically connected to the first feed via, each of the first feed patterns having a width greater than a width of the first feed via and a cross-sectional area smaller than a cross-sectional area of the patch antenna pattern; and
a plurality of second feed patterns disposed on the second side of the patch antenna pattern on different levels and overlapping each other,
wherein the plurality of first feed patterns is spaced apart from the plurality of second feed patterns,
wherein the patch antenna pattern is spaced apart from a highest first feed pattern of the first feed patterns and spaced apart from a highest second feed pattern of the second feed patterns without conductive patterns therebetween in a thickness direction of the antenna apparatus, and
wherein the plurality of first feed patterns do not overlap the plurality of second feed patterns in the thickness direction of the antenna apparatus.
