摘要：
The present invention provides a beamforming antenna (100, 200, 400) comprising a plurality of antenna elements (101, 102, 201, 202, 401, 402, 440), and a signal generator (103, 403) that is configured to generate for each one of the antenna elements (101, 102, 201, 202, 401, 402, 440) a calibration signal (106, 107, 206, 406, 335) for radiation by the respective antenna element (101, 102, 201, 202, 401, 402, 440) and to supply the generated calibration signals (106, 107, 206, 406, 335) to the respective antenna elements (101, 102, 201, 202, 401, 402, 440). Further, the present invention provides a measurement device (330, 430) for measuring properties (336) of a beamforming antenna (100, 200, 400) according to any one of the preceding claims via calibration signals (106, 107, 206, 406, 335) emitted by antenna elements (101, 102, 201, 202, 401, 402, 440) of the beamforming antenna (100, 200, 400), the measurement device (330, 430) comprising a measurement receiver (332) that is configured to receive an incoming signal (334) comprising the calibration signals (106, 107, 206, 406, 335), and a property determination module (333) that is coupled to the measurement receiver (332) and that is configured to determine the properties (336) of the beamforming antenna (100, 200, 400) based on the received calibration signals (106, 107, 206, 406, 335). Further, the present invention provides a respective antenna measurement system (450) and a respective method.
