Abstract
Coaxial waveguide apparatus for conducting radio signals within a range of frequencies including an waveguide having an open end and a rear wall opposite the open end positioned along an axis of the waveguide and defining a waveguide cavity with a fundamental waveguide mode within the waveguide. The waveguide is constructed with a cutoff frequency for the fundamental waveguide mode which is at least 95% of the lowest frequency for the apparatus. A center conductor is positioned within the waveguide cavity and along the axis of the waveguide so that the center conductor and the waveguide define a coaxial waveguide cavity.
