Abstract
An antenna feed with mode suppression includes a transition section, having a window for connecting to an output port of a waveguide and having inner and outer conductors forming a coaxial waveguide that couples energy from the waveguide into a horizontal TE11 mode in the coaxial waveguide. A polarizer section is coupled to the transition section and generates circular polarization from the horizontal mode of the transition section. A radiator section is coupled to the polarizer and provides an output signal for the antenna feed. The transition section includes an electrical short coupling the inner and outer conductors. The electrical short is disposed adjacent to the window of the transition section. A dielectric block is also disposed between the inner and outer conductors and adjacent to the electrical short along the axis of the coaxial waveguide. A surface of the dielectric block is coated with a thin film sheet resistance.
