Abstract: A calibration system for calibrating a number of transceivers, each comprising an in-phase signal path and a quadrature signal path in receive direction and/or in transmit direction is disclosed herein. The calibration system includes a calibration signal generator that is configured to generate a predefined calibration signal for every one of the transceivers, a calibration transceiver that is coupled to the calibration signal generator and to the transceivers and that is configured to supply the generated predefined calibration signals each to the respective transceiver during operation of the transceivers, and/or that is configured to receive the predefined calibration signals after they travel through each one of the transceivers during operation of the transceivers, and a calibration unit that is configured to calibrate the in-phase signal paths and the quadrature signal paths of the transceivers during operation of the transceivers based on the calibration signals as they are received by the transceivers or based on the calibration signals as they are received by the calibration transceiver. Further, an antenna system and a calibration method are also described.

Abstract: An antenna test system for testing an antenna with a plurality of antenna elements is disclosed. The antenna test system includes an antenna element connector for every antenna element of the antenna, wherein the antenna element connectors are wiredly couplable to the respective antenna elements, a channel emulator comprising an antenna port for every antenna element connector and a number of test signal ports, and a signal evaluation device for every one of the test signal ports that is coupled to the respective test signal port and that in each case is configured to receive a downstream test signal from the channel emulator and to evaluate the received downstream test signal and/or to provide an upstream test signal to the channel emulator via the test signal port, wherein the channel emulator is configured to receive downstream signals emitted by the antenna elements at the antenna ports and to perform a channel emulation on the received downstream signals and to output on each test signal port a single respective downstream test signal, and/or wherein the channel emulator is configured to receive upstream test signals from the respective signal evaluation devices via the test signal ports and to perform a channel emulation on the received upstream test signals and to output on each antenna port a respective upstream signal.
