Abstract : An array of five ridge waveguide horns provides monopulse operation over a two octave range. A unique coax to ridge waveguide input coupler and an extended ridge matching section at the radiating apertures provide the extended frequency range. The horn assembly is lightweight, compact and suitable for array applications. A five horn monopulse primary feed array is exemplified.
