Title:
APPARATUS FOR MEASURING ANTENNA RADIATION PATTERN
Document Type and Number:
WIPO Patent Application WO/2015/174786
Kind Code:
A1
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.
