Research is proposed into the use of non-planar geometries for anti-jam GPS receiving antennas. The global positioning system (GPS) is an essential tool for military navigation. Unfortunately, GPS receivers are vulnerable to jamming, which can severely degrade performance, resulting in a need for anti-jam technologies to protect GPS receiving systems. Concept feasibility will be assessed by modeling and evaluating Combined Radiation Pattern Antennas (CRPAs) with cylindrical and spherical geometries, and comparing the null-forming performance of these antennas to a planar baseline antenna.
