Abstract

A coaxial feed for multiband antenna for a multiband antenna includes: a tubular high-band (HB) waveguide, the HB waveguide including an outer conducting surface, an inner HB conducting surface, and a HB aperture defined by the inner HB conducting surface; a tubular low-band (LB) waveguide disposed coaxially around the HB waveguide, the LB waveguide including an outer feed surface, an inner LB conducting surface, and an annular LB aperture defined by the inner LB conducing surface and the outer conducting surface of the HB waveguide; and an annular high-band (HB) choke located in the outer conducting surface of the HB waveguide, the HB choke being axially offset from the HB aperture.
