This invention discloses a method and a device for calibrating smart antenna array, which is used to calibrate smart antenna array in real time, comprising: setting coupling structure, feeder cables and pilot transceiver together as a calibrating link; pre-calibrating the couple structure with vector network analyzer and recording its receiving and transmitting transmission coefficient respectively; making receiving calibration to smart antenna array by adjusting transmission coefficient of each receiving link and reference link to a same amplitude and phase difference PHI is recorded and stored in baseband processor; making transmitting calibration by adjusting transmission coefficient of each transmitting link and reference link to a same amplitude and phase difference PSI is recorded and stored in baseband processor. The coupling structure of the invention is implemented by pilot antenna using spatial couple mode or passive network. <IMAGE> |
