ANTENNA TEST SYSTEM AND A METHOD FOR TESTING AN ANTENNA

Abstract:

An antenna test system for testing an antenna with a plurality of antenna elements is disclosed. The antenna test system includes an antenna element connector for every antenna element of the antenna, wherein the antenna element connectors are wiredly couplable to the respective antenna elements, a channel emulator comprising an antenna port for every antenna element connector and a number of test signal ports, and a signal evaluation device for every one of the test signal ports that is coupled to the respective test signal port and that in each case is configured to receive a downstream test signal from the channel emulator and to evaluate the received downstream test signal and/or to provide an upstream test signal to the channel emulator via the test signal port, wherein the channel emulator is configured to receive downstream signals emitted by the antenna elements at the antenna ports and to perform a channel emulation on the received downstream signals and to output on each test signal port a single respective downstream test signal, and/or wherein the channel emulator is configured to receive upstream test signals from the respective signal evaluation devices via the test signal ports and to perform a channel emulation on the received upstream test signals and to output on each antenna port a respective upstream signal.
