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.
