Summary: | According to one embodiment of the present invention, provided is an antenna device capable of improving antenna performance or easily performing miniaturization while providing transmission/reception means for a plurality of different frequency bands. The antenna device comprises: a feed line; a ground plane surrounding a portion of the feed line; a feed via electrically connected to the feed line; a first endfire antenna pattern disposed in front of the ground plane and electrically connected to the feed via; a second endfire antenna pattern electrically connected to the feed line and disposed further ahead of the first endfire antenna pattern; and a third endfire antenna pattern electrically connected to the feed via and disposed in front of the first endfire antenna pattern so that at least a portion thereof overlaps a second endfire antenna.
