The design of millimetrewave antenna measurement systems

Describes a study of the available technology for the measurement of antenna radiation patterns in the frequency range 90 GHz to 200 GHz. Several systems are proposed having theoretical dynamic ranges of between 40 dB and 84 dB at 180 GHz. Facilities such as RF phase measurement and time domain gating are considered. Experimental results with a system demonstrating a dynamic range of 62 dB and 180 GHz are also described.<
