Abstract:

A type of wide flare feed which produces low spillover, high aperture efficiency and broad bandwidth is described. This feed operates with no loss of its high performance characteristics over a full waveguide band and more and takes full waveguide power. It has low VSWR, supports linear, circular, or dual polarization, and has in herently low cross-polarization. Many primary and secondary performance characteristics are described, which verify the high gain, low sidelobe, and low noise temperature features. As a tracking feed it can be used with multimode inputs, either the TE11 and TM01 mode circular guide type or the two or four horn monopulse type. The feed operates well in the former system but has unsolved problems in monopulse operation involving controlled mode excitation at the throat. Author
