The microwave anechoic chamber is extensively being applied in antenna measure- ment projects. An automatic measurement system in microwave and millimeter wave anechoic chamber for antenna feed source is introduced, whose composition, primary function, work principle and software design are described schematically. Frequency bands of the system ran- ges from 100 MHz to 50 GHz, which works at three different frequency modes including 100 MHz to 300 MHz, 300 MHz to 18 GHz and 18 GHz to 50 GHz, respectively. The realized scheme of the automatic measurement system is described in details in condition of different work modes. Finally, some measurement results of feeding network at C/Ku band are given in certain engineering. The measurement results indicate that the system has high-efficiency, high accuracy and high automatic measuring ability and can be applied well in the actual meas- urement projects.
