Quiet Area Tests of a Ka-band Compact Range

Because of the limited size of a common microwave anechoic chamber, compact range testing methods have been developed to be a hot spot in recent years. But an ordinary compact range can not meet the need of millimeter wave (with high frequency, 200MHz similar to 20GHz) test. So this article uses a millimeter compact range to do the test at Ka-band, and the main purpose of the test is to determine the range of compact range quiet area. Based on the test results, the quiet area of the millimeter compact range is about 400mm*400mm at the distance of 3m to the center of the reflecting surface, and the quiet area is of pretty good property.
