US Patent 11175337 Over-the-air measurement system

An over-the-air measurement system for performing over-the-air measurements on a device under test is described. The measurement system comprises a measurement device having several measurement antennas, several waveguides, wherein at least one waveguide is assigned to each measurement antenna, several waveguide-to-cable adapters, and a positioning unit assigned to the measurement antennas. The number of the waveguide-to-cable adapters is at least identical to the number of the measurement antennas. The positioning unit is configured to move the measurement antennas with respect to the waveguide-to-cable adapters.
