Patent ID: 11340278

Abstract:
The present disclosure relates to a measurement system for testing a device under test over-the-air, the measurement system comprising a signal generation and/or analysis equipment, several antennas, several reflectors and a test location for the device under test. The antennas are connected with the signal generation and/or analysis equipment in a signal-transmitting manner. Each of the antennas is configured to transmit and/or receive an electromagnetic signal so that a beam path is provided between the respective antenna and the test location. The electromagnetic signal is reflected by the respective reflector so that the electromagnetic signal corresponds to a planar wave. Each antenna aims at a focal point of the corresponding reflector. Each antenna and the corresponding reflector together are configured to provide a corresponding quiet zone at the test location. At least two of the several antennas are located within a main plane, whereas at least one of the several antennas is located in an auxiliary plane that is offset with respect to the main plane.
