Abstract: Disclosed is a radio wave device test system, comprising a fixed part configured to fix a radio wave device; a positioner system configured to control a rotation of the radio wave device by controlling the fixed part; an arch structure whose central point is located at a position where the radio wave device is located; a plurality of probes disposed to be spaced apart from one another at fixed intervals in the arch structure, and configured to receive a radio frequency (RF) signal from the raid wave device; and a plurality of receiving modules located at the plurality of probes, respectively, and configured to transform the RF signal into in-phase/quadrature (I/Q) data by carrying out digital transformation for the RF signal and to detect information on amplitude and a phase from the I/Q data.

Abstract: An apparatus for measuring an antenna radiation pattern comprises a lower bearing unit; a hollow mast which is installed in the vertical direction; a hollow vertical bar, the length of which is vertically adjustable in a state; 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; a first mounting unit, the length of which is vertically adjustable in a state; a second mounting unit having a vertical shaft which is coupled to the horizontal shaft by vertically penetrating one end of the horizontal shaft, 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.
