Zusammenfassung:According to one embodiment of the present invention, provided is an antenna device comprising: a patch antenna pattern; a feed via electrically connected to a point biased in a first direction from the center of the patch antenna pattern; a plurality of side coupling patterns disposed to be spaced apart from each other in a second direction and the opposite direction of the second direction from the patch antenna pattern; and a plurality of side ground patterns disposed to be spaced apart from the patch antenna pattern in the first direction and the opposite direction of the first direction respectively, and disposed such that the patch antenna pattern and the plurality of side coupling patterns are disposed therebetween. The antenna device of the present invention may improve antenna performance such as gain, bandwidth, directivity, and the like, or may have a structure advantageous for miniaturization. 본 발명의 일 실시 예에 따른 안테나 장치는, 패치 안테나 패턴과, 패치 안테나 패턴의 중심에서부터 제1 방향으로 치우쳐진 지점에 전기적으로 연결되는 피드비아와, 패치 안테나 패턴으로부터 제2 방향 및 제2 방향의 반대방향으로 각각 이격되어 배치된 복수의 사이드 커플링 패턴과, 패치 안테나 패턴으로부터 제1 방향 및 제1 방향의 반대방향으로 각각 이격되어 배치되고 패치 안테나 패턴과 상기 복수의 사이드 커플링 패턴이 사이에 위치하도록 배치된 복수의 사이드 그라운드 패턴을 포함할 수 있다.
