description The present invention provides a beamforming antenna (100, 200) for multi-carrier transmission with multiple sub-carriers, the beamforming antenna (100, 200) comprising a number of signal paths (101, 102, 103, 571, 572) configured to transmit and receive communication signals, a calibration signal (108, 109, 110, 111, 208, 211, 308) generator (107, 207) that is configured to generate for the signal paths (101, 102, 103, 571, 572) a number of calibration signals (108, 109, 110, 111, 208, 211, 308) with the sub-carriers of the multi-carrier transmission in the frequency domain, the calibration signals (108, 109, 110, 111, 208, 211, 308) comprising a calibration sub-signal in at least one of the sub-carriers of the respective calibration signal (108, 109, 110, 111, 208, 211, 308), and a supply element (112, 113, 114, 115, 212, 213, 214) configured to supply the calibration signals (108, 109, 110, 111, 208, 211, 308) to the respective signal paths (101, 102, 103, 571, 572). Further, the present invention provides a respective measurement device (680) and a respective method.
