ABSTRACT:
A corrugated horn having ridges disposed on the inner surface of the horn, such that the ridges are oriented parallel to the horn axis, is adapted to provide elliptical beams. When the corrugated horn is circular, the elliptical beam is produced by changing the step heights and/or ridge heights around the circumference of the horn, which in turn changes the semi-flare angle, defined as the angle made by the horn axis and a line joining the top surfaces of the ridges. Because corrugated horns constructed according to this invention have ridges oriented parallel to the horn axis, these corrugated horns are readily manufactured using conventional die casting methods or numerical machining techniques.
