The present invention relates to an antenna radiation pattern measuring device and, more specifically, an antenna radiation pattern measuring device comprises: a lower base portion; a hollow mast which is vertically installed on the basis of a center portion of the lower base portion; a hollow vertical rod, a length of which is vertically adjusted in a state of being slid and inserted therein through an upper end of the mast; a goniometer which is horizontally coupled to the upper portion of the vertical rod; a horizontal shaft which is positioned upside the goniometer and is horizontally coupled to the upper portion of the vertical rod to rotate forward and backward; a first holding unit, a length of which is vertically adjusted in a state of being slid and inserted therein through the upper end of the vertical rod, and on which an antenna is placed on the upper face thereof; a vertical shaft which vertically penetrates one end of the horizontal shaft to be coupled; a second holding unit which includes an antenna fixing jig installed at the upper end of the vertical shaft; and a support unit which has one end coupled to the horizontal shaft and the other end coupled to thean outer diameter of the mast. According to the present invention, there is an effect capable of easily and conveniently measuring a the radiation pattern of an antenna while manually rotating the antenna at a regular angle, in which a the center of a horn antenna opening front face is a vertical shaft, in an outdoor test site, an electromagnetic anti-reflective room, or the like. |
