An accurate operation of wideband multi-port reflectometer with new calibration method implementing least mean square for microwave imaging application

The wideband operation of multi-port reflectometer may lead to inaccurate reflection coefficient measurement caused by the overlapped phase characteristics of the used calibration standards. Therefore, a calibration procedure implementing Least Mean Square (LMS) is proposed to offer accurate operati...
