Abstract
A system for phase calibration of an antenna array comprises at least two antenna elements. The system furthermore comprises a device under test comprising the antenna array, a plane wave converter, and a phase measuring unit. Whereas the device under test is configured to transmit or receive a test signal with spatially dependent phase, the plane wave converter is configured to convert the test signal with spatially dependent phase into a signal with constant phase. In addition to this, the device under test or the phase measuring unit is configured to derive calibration values for the phase calibration of the antenna array from the signal with constant phase.
