The analysis and low‐power testing of a square miltiflare horn designed‐for 1‐megawatt CW operation is described. Design considerations for the five‐port input section are discussed. The required aperture modes are determined from radiation pattern considerations, and analysis of the multiflare section is carried out using mode matching. Measurements demonstrate that a circularly symmetric beam is produced with relatively low sidelobes.
