An antenna apparatus includes a patch antenna pattern; a first feed via to feed power to the patch antenna pattern in a non-contact manner on a first side of the patch antenna pattern; and a plurality of 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, and each 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.

Antenna apparatus

An antenna apparatus may include: a substrate; two feed vias disposed in the substrate; and an antenna pattern disposed on one surface of the substrate, and including a central portion and wing portions protruding from the central portion. A first wing portion and a second wing portion adjacent to the first wing portion, among the wing portions, may be disposed over the two feed vias. The antenna apparatus may be configured to selectively provide a feed signal to either one or both of the two feed vias.

An antenna apparatus includes a feed line; a ground plane surrounding a portion of the feed line; a feed via electrically connected to the feed line and extending from a first side of the feed line; a first end-fire antenna pattern disposed on a first side of at least a portion of the ground plane and spaced apart from the ground plane, and electrically connected to the feed via; a second end-fire antenna pattern disposed on a second side of the feed line opposite the first side of the feed line and spaced apart from the first end-fire antenna pattern; and a core via electrically connecting the first end-fire antenna patterns to the second end-fire antenna pattern.
