Abstract
An antenna apparatus includes: a ground plane having a through-hole; a feed line disposed below the ground plane; an insulating layer disposed between the feed line and the ground plane; a feed via electrically connected to the feed line, and passing through the through-hole; and a chip patch antenna electrically connected to the feed via. The chip patch antenna includes: a patch antenna pattern electrically connected to the feed via; an upper coupling pattern disposed above the patch antenna pattern; edge coupling patterns surrounding a portion of the patch antenna pattern; upper edge coupling patterns surrounding a portion of the upper coupling pattern; and a dielectric layer disposed in a first region between the patch antenna pattern and the upper coupling pattern, and in a second region between the edge coupling patterns and the upper edge coupling patterns, and having a dielectric constant higher than that of the insulating layer.
