The present disclosure relates to a compact antenna test range (CATR) system. The CATR system comprises a measurement chamber, at least one feed antenna which is configured to transmit a radio frequency, RF, signal, at least one reflector which is arranged to reflect the RF signal towards a measurement area in the measurement chamber, and at least two preferably metallic calibration surfaces which can be arranged at two or more positions in the measurement area, wherein the calibration surfaces are configured to reflect a respective reflection of the RF signal back to the at least one reflector which is, in turn, configured to reflect the reflections of the RF signal back to the at least one feed antenna. The CATR system further comprises a measurement unit which is configured to receive the respective reflections of the RF signal and to determine and/or visualize a time difference between the reception of the respective reflections of the RF signal.

A system for the automated validation of a semi-anechoic chamber (SAC) is disclosed. The system includes a receive assembly and a transmit assembly, each configured to autonomously relocate within the SAC. The system also includes a local client communicatively coupled to the transmit assembly. The local client is configured to send a validation arrangement to the transmit assembly describing a validation location and a distance. The transmit assembly is configured to receive the validation arrangement, move the transmit assembly to the validation location and send an instruction to the receive assembly, the instruction describing the distance. The receive assembly is communicatively coupled to the transmit assembly and configured to receive the instruction and move the receive assembly such that a separation between the transmit and receive assemblies is restored to the distance. Each validation arrangement corresponds to a validation point. A plurality of validation points defines a test volume.

A near-field test system for a phased array antenna includes a probe, a beam forming network, and a computing system. The probe is disposed at a fixed position in a near-field of the phased array antenna and transmits a test beam toward a fixed location on the phased array. The beam forming network is coupled to the phased array and includes a plurality of phase shifters and a beam summer. The phase shifters steer received beams for each antenna element of the phased array to form a planar wave front. The beam summer is coupled to the phase shifters and combines power of the received beams. The computing system is coupled to the beam forming network and scales combined power of the received beams and generates a virtual spectrum for the phased array antenna from scaled power of the received beams.

An evaluation device includes a radio communication module that contains a temperature regulator that adjusts a temperature of a radio communication module to be evaluated, a housing case that houses the radio communication module and the temperature regulator, a gas supplier that supplies dry gas inside the housing case, and a measurement antenna that is disposed so as to face the radio communication module, and that transmits and receives radio waves for measurement. The housing case includes a case main body and a shutter plate that closes an opening of the case main body. The shutter plate is formed of a dielectric foam material, and the shutter plate is capable of contacting and separating from an open edge of the case main body. At least a part of the shutter plate separates from the open edge of the case main body to release gas from inside the housing case when an inner pressure of the housing case is greater than or equal to a predetermined value.

There is provided mechanisms for OTA calibration of an AAS. The AAS comprises N antenna branches, each of which comprises a respective subarray. The subarray of each antenna branch gives rise to a subarray antenna pattern extending over an angular interval. A method is performed by a test equipment. The method comprises obtaining measurement values for each of the antenna branches. At least one measurement value is obtained per each antenna branch. The method comprises determining one calibration factor value per antenna branch using the measurement values and taking the subarray antenna patterns into account. The method comprises applying the determined calibration factor values to the N antenna branches, thereby calibrating the AAS.
