Abstract
An antenna apparatus includes a ground layer having a through-hole; a feed via disposed to pass through the through-hole; a patch antenna pattern disposed on the ground layer and electrically connected to one end of the feed via; a first coupling patch pattern disposed on the patch antenna pattern; a second coupling patch pattern disposed between the first coupling patch pattern and the patch antenna pattern; and a dielectric layer disposed in at least of a portion a space between the first coupling patch pattern and the second coupling patch pattern so that a dielectric constant of at least a portion of a space between the patch antenna pattern and the second coupling patch pattern is lower than a dielectric constant of the space between the first coupling patch portion and the second coupling patch pattern.
