ANECHOIC TEST CHAMBER, TEST SYSTEM AND TEST METHOD FOR TESTING THE ANTENNAS OF A DEVICE UNDER TEST

摘要

This application relates to an anechoic test chamber for testing antennas of a device under test (DUT), the test chamber comprising: a test area having a test surface for receiving the DUT, wherein in a test mode the test surface forms a region of measurement of the DUT and wherein the DUT comprises at least one antenna array having a plurality of multi-input multi-output (MIMO) antennas, at least one reflector compact antenna test range (CATR) comprising a first measurement antenna and one shaped reflector, wherein the reflector is used to generate a first quiet zone, at least one second measurement antenna, wherein the second measurement antenna is arranged inside the test chamber such to generate a second quiet zone at test surface, an input/output terminal for connecting the test chamber to a test equipment, wherein the input/output terminal is connected to the first and second antennas.
