Abstract The present invention relates to an apparatus for measuring an antenna radiation pattern and, more specifically, to an apparatus for measuring an antenna radiation pattern, comprising: a lower bearing unit; a hollow mast which is installed in the vertical direction with respect to the central portion of the lower bearing unit; a hollow vertical bar, the length of which is vertically adjustable in a state where the hollow vertical bar is slidably inserted into the mast through the upper end of the mast; a goniometer which is horizontally coupled to the upper part of the vertical bar; a horizontal shaft which is positioned at the upper part of the goniometer and is horizontally coupled to the upper part of the vertical bar so as to be clockwise or counterclockwise rotatable; a first mounting unit, the length of which is vertically adjustable in a state where the first mounting unit is slidably inserted into the vertical bar through the upper end of the vertical bar, and on the top surface of which an antenna is mounted; a vertical shaft which is coupled to the horizontal shaft by vertically penetrating one end of the horizontal shaft; a second mounting unit having a jig for fixing the antenna, the second mounting unit being installed on the upper end of the vertical shaft; and a support unit of which one end is coupled to the horizontal shaft and the other end is coupled to the outer periphery of the mast. The present invention has an effect that an antenna radiation pattern can be easily and conveniently measured in an open area test site, an electromagnetic anechoic chamber, etc. while manually rotating at a predetermined angle with respect to the center of the front side of an opening of a horn antenna as a vertical axis. L'invention concerne un appareil destiné à mesurer un motif de rayonnement d'antenne et, plus particulièrement, un appareil comprenant : une unité d'appui inférieure ; un mât creux disposé verticalement par rapport à la partie centrale de l'unité d'appui inférieure ; une barre verticale creuse dont la longueur est réglable verticalement dans un état dans lequel ladite barre est insérée de façon coulissante dans le mât par l'extrémité supérieure de ce dernier ; un goniomètre couplé horizontalement à la partie supérieure de la barre verticale ; un arbre horizontal disposé au niveau de la partie supérieure du goniomètre et couplé horizontalement à la partie supérieure de la barre verticale de sorte à tourner dans le sens horaire ou antihoraire ; une première unité de montage dont la longueur est réglable verticalement dans un état dans lequel la première unité de montage est insérée de façon coulissante dans la barre verticale par l'extrémité supérieure de cette dernière, et sur la surface supérieure de laquelle est montée une antenne ; un arbre vertical couplé à l'arbre horizontal par son insertion verticale dans une extrémité de l'arbre horizontal ; une deuxième unité de montage pourvue d'un gabarit servant à fixer l'antenne, cette deuxième unité de montage étant disposée sur l'extrémité supérieure de l'arbre vertical ; et une unité de support dont une extrémité est couplée à l'arbre horizontal et l'autre extrémité est couplée au périmètre externe du mât. La présente invention permet de mesurer facilement et de façon pratique un motif de rayonnement d'antenne sur un site d'essai en zone ouverte, une chambre anéchoïque électromagnétique, etc., tout en assurant une rotation manuelle à un angle prédéterminé par rapport au centre du côté avant d'une ouverture d'antenne-cornet servant d'axe vertical. 본 발명은 안테나 방사 패턴 측정장치에 관한 것으로서, 더욱 상세하게는 하부 받침부와, 하부 받침부의 중앙부위를 기준으로 수직방향으로 설치된 중공의 마스트와, 마스트의 상단을 통해 내부에 슬라이딩 삽입된 상태로 수직방향으로 길이조절되는 중공의 수직봉과, 수직봉의 상부에 수평으로 결합 된 각도계와, 각도계의 상측에 위치하며, 수직봉의 상부에 정역회전가능하게 수평으로 결합 된 수평축과, 수직봉의 상단을 통해 내부에 슬라이딩 삽입된 상태로 수직방향으로 길이조절되며, 상면에 안테나가 안착 되는 제1거치부와, 수평축의 일단을 수직으로 관통하여 결합 된 수직축과, 수직축의 상단에 설치된 안테나 고정용 지그를 구비한 제2거치부 및 수평축에 일단이 결합 되고, 타단이 마스트의 외경에 결합 된 지지부를 포함하는 안테나 방사 패턴 측정장치에 관한 것이다. 본 발명에 따르면, 야외시험장 또는 전자파 무 반사실 등에서 수동으로 혼 안테나 개구부 앞면의 중심을 수직축으로 하여 일정한 각도로 회전시키면서 쉽고 편리하게 안테나의 방사 패턴을 측정할 수 있는 효과가 있다.
