Abstract

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.
