Abstract
An antenna apparatus includes: a feed via; a patch antenna pattern electrically connected to one end of the feed via; a ground layer disposed in a position vertically lower than a position of the patch antenna pattern, and having a through-hole through which the feed via passes; a first conductive ring pattern laterally spaced apart from the patch antenna pattern, and having a first through region laterally surrounding the patch antenna pattern; and a second conductive ring pattern disposed in a position vertically higher than a position of the first conductive ring pattern, and having a second through region laterally surrounding the patch antenna pattern, wherein an area of the second through region is greater than an area of the first through region.
