  • Calibration device and calibration method for calibrating antenna arrays
    Patent number: 10527714
    Abstract: A calibration device for calibrating an antenna array is provided. The calibration device comprises a transmitter, which is configured for transmitting a first calibration signal to all antennas of the antenna array, resulting in a plurality of received first calibration signals provided by the antenna array to the calibration device. Moreover, the calibration device comprises a receiver, which is configured for receiving a plurality of second calibration signals from the antennas of the antenna array. Finally, the calibration device comprises an antenna characteristic calculator, which is configured for calculating an antenna characteristic of each individual antenna of the antenna array based on the plurality of received first calibration signals and the plurality of received second calibration signals.
