The goal of this array is to achieve high gain at a low cost for improved carrier-to-noise density ratio C/N0 when implemente d with adaptive beamforming and spatial combination. Different methods are explored to implement these algorithms blindly with no prior information known about the array. COTS absorber materials are investigated for mutual coupling suppression to improve adaptive beamforming and spatial combinat ion performance. The final subarray design is inherently expandable to mul tiple subarrays and suitable for mounting on ground-based mobile platforms \, unlike traditional dish antennas\, which are more expensive and larger. Several subarray geometries were investigated to assess performance while complying with Size\, Weight\, Power\, and Cost (SWAP-C) requirements.\n\ nBio: Capt Ethan Ward is a Developmental Engineer (62E) and recently gradu ated with an M.S. in Electrical Engineering at the Air Force Institute of Technology. His research focused on antenna array design for a 16-channel GPS/GNSS receiver front-end. He received a B.S. in Electrical and Computer Engineering from Oregon State University and commissioned into the U.S. A ir Force in March 2022. Following his commission\, he worked as an enginee r on the AN/FPS-132 Upgraded Early Warning Radars (UEWR) at Peterson SFB\, CO.
