Document Type and Number:
WIPO Patent Application WO/2023/090517
Kind Code:
A1
Abstract:
Disclosed are a system and a method therefor, the system enabling high-speed measurement of the performance of a plurality of measurement items for verification and post management of equipment under test including an antenna under test. According to one aspect of the present invention, provided is a system for measuring the performance of equipment under test, comprising: a fixing part for fixing the equipment under test, which is to be tested; a positioner for controlling the rotation of the equipment under test by controlling the fixing part; a measurement probe, which is provided at a predetermined position spaced apart from the fixing part while being hidden from the line-of-sight of the equipment under test; a curved reflective plate for reflecting, in the direction of the measurement probe, an electromagnetic wave radiated by the equipment under test and transforming the spherical wave of the measurement probe into a plane wave at the position where the equipment under test is provided; an arc structure including an arc arranged to be adjacent to the fixing part so that the position of the equipment under test is the center point of the arc; a probe set including a plurality of near-filed probes arranged to be spaced predetermined intervals apart from each other on the inner side of the arc; and a control unit, which receives, through a signal analyzer, signal data corresponding to an input signal from at least some of the plurality of near-filed probes and the measurement probe in order to measure the performance of the equipment under test.
