摘要: A method for antenna calibration is disclosed, the comprising driving signals array beam to an feeder line in a transceiver front end unit by using one or more directional couplers and/or radio frequency probes, wherein signal paths are integrated inside unit. Measurements carried out on signals, between different combinations array. Based collected measurement data, information calculated each branch of mathematical formula. Active then performed based information.
