Abstract:
A splashplate antenna system configured using hybrid mode-matching techniques has improved secondary beam characteristics, including improved sidelobe performance, improved electric and magnetic plane correlation, reduced cross-polarization, improved electric and magnetic plane phase center correlation, and improved overall matching between the waveguide and the splashplate (sub-reflector). Internally, the waveguide contains a wall constructed from a series of varying dimensioned cross-sections that cause signals introduced to radiate in a multiple mode, Gaussian-like field pattern. The Splashplate is configured so that the waves received from the waveguide maintain the circular pattern symmetry, as well as other characteristics.
