Physical Sciences Inc. (PSI) has been awarded a contract from the U.S. Air Force to develop a high-power electrically tuned phase shifter to form high-power microwave (HPM) antenna arrays with electronic beam steering capability. In this Phase I SBIR proposal, Physical Sciences Inc outlines the development of a waveguide-based phase shifter that will enable 20° azimuth/elevation beam steering for conformal megawatt and gigawatt class antenna arrays. This technology has the potential to replace complex and expensive mechanically steered apertures with an electrically tuned, low loss X-band device.
In Phase I, PSI will refine the design of a novel, electrically tuned phase shifter. PSI will optimize the differential phase shift per dB of insertion loss while ensuring megawatt power handling. During Phase I, PSI will design and build an X-band prototype to demonstrate proof of principle through an experiment. PSI will complete Phase I with a mature design for manufacture of the phase shifter with corresponding high-power simulations. During Phase II, PSI will transition the phase shifter to an operational system and demonstrate a sub-array with 20° azimuth/elevation steering.
