Abstract : This project investigated architectures, radiators, FET amplifiers and oscillators that could be used in monolithic millimeter wave phased arrays. These investigations contribute to an understanding of the performance of integrated phased arrays. For example, scan blindness associated with surface waves and competition with active components for limited substrate surface area lead to designs with more than one substrate. It has been shown that feed lines can couple electromagnetically to microstrip paths through apertures in an intervening ground plane, and this allows using the beat substrate for each function. Injection locked oscillators using FETs in microstrip and coplanar waveguide circuits were developed as phase controlled sources for transmitter or local oscillators.
