A line source of sixteen 5-bit MEMS phase shifters was used for beam scan of a novel X-band CTS (Continuous Transverse Stubs) antenna over +/-45 degrees in the H-plane. The 5-bit phase shifter has 1 dB loss on average over 6 -10 GHz. The building block of these phase shifters is a cantilevered MEMS switch developed by HRL Laboratories.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
