Millimeter-wave feed horn exhibits nearly equal beam-intensity patterns in E- and H-planes as well as low side-lobe levels. Horn includes circular waveguide step transition, and conical section. Design simplified version of Potter feed-horn design. New feed horn easier to construct, in part because of simpler shape. Reduction in phase change between step transition and aperture increases bandwidth, thereby reducing precision required to manufacture phase-sensitive dimensions of horn.
