Multiband Metasurface for Reduced Antenna Footprint and Jamming Mitigation
ABSTRACT: The Team will design and develop an antenna design operating at 20, 44, and 60 GHz (K/V) band. We will be basing our new design on a previously successful Phase II SBIR using independently moving metasurface antennas. This new design will take advantage of electronic steering and use multiple apertures sandwiched together. This multiband metasurface antenna can be scaled and adapted to work in tandem with existing antenna structures on the satellite. This antenna will be capable of simultaneous operation at all bands, beam steering, and adjusting coverage area. Most importantly, the entire antenna structure will appear"invisible"at frequencies outside the operating band. Therefore, the antenna can be placed on the satellite with minimal considerations to RFI and RFC. The result will be an antenna that provides an add on upgrade capability to the satellite. We conclude by developing a proof of concept and demonstrating, analytically and with breadboard hardware, the feasibility of meeting the Air Force"s requirements. The team intends to use heavy modeling and simulation for initial investigation of design approaches will initially be used. Small-scale models will eventually be used to demonstrate the proof of concept by implementing single aperture operation at multiple RF bands. BENEFIT: This research effort will yield multiband metasurface antenna that provides an add on upgrade capability to the satellite. This antenna can be used to upgrade the desired platform with minimal considerations to RFI/RFc.
