Abstract: A method for performing active over-the-air measurements of a device under test with an antenna is described. The device under test with the antenna is provided. The device under test is arranged randomly in a measurement zone assigned to a measurement antenna. The phase center of the antenna of the device under test is determined. Measurement positions for the active over-the-air measurements are calculated that depend on an offset between the phase center determined and a center of the measurement zone. Further, a measurement system for over-the-air measurements is described.

Abstract: A method for performing a radiated two-stage method measurement on a device under test having a predefined number of antennas, comprising: placing the device under test on a positioner; establishing communication with the device under test using at least one link antenna; and measuring the antenna pattern of the device under test using a plurality of measurement antennas, wherein the plurality of measurement antennas comprise a number of measurement antennas being larger than the number of antennas of the device under test. Further, a measurement setup is shown.

Abstract: A testing method for testing mobile communication devices comprises measuring a three-dimensional antenna pattern of an active phased antenna array (AAS) of the mobile communication device, with the AAS being maintained at a specific beamforming alignment during the measurement. A predefined base fading profile is calibrated with the measured three-dimensional antenna pattern to obtain an optimized fading profile adapted to the specific beamforming alignment. A channel model for emulation of a base station is emulated on the basis of the optimized fading profile. The method further involves performing a receiver test on the mobile communication device using the emulated channel model. The testing method may in some embodiments be a radiated two-stage over-the-air (RTS-OTA) testing method.
