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.
