Abstract: An undesired resonance is prevented in a distributed transmission line filter comprising a center conductor having serially connected inductive and capacitive sections separated from a ground conductor by a dielectric substrate having a first thickness for filter inductive sections and a second thickness for at least one of filter capacitive sections.

Abstract: A radiating waveguide horn is provided having a hollow tubular portion and significantly broader radiating portion. The hollow tubular portion is adapted to coaxially receive therein a closely spaced rectangular waveguide feed structure. The waveguide feed structure is dimensioned to pass easily within the hollow tubular portion leaving a gap between the waveguide feed structure and the inner surface of the hollow tubular portion of the waveguide horn. A pair of elongated curved metal strips are fixed to one end of the waveguide feed structure with the metal strips generally extending along the length of said structure. The metal strips are configured and arranged relative to opposite walls of the waveguide feed structure so that the strips make flexible contact with the inner surface of the hollow tubular portion of said horn.
