Pyramidal horns. II. A novel design method for horns of any desired gain and aperture phase error

For pt.I see ibid., p.1435 (1989). The authors present a novel numerical method for determining the exact pyramidal horn dimensions for any desired gain. It utilizes exact relationships to yield the required aperture dimensions and horn length, given an operating frequency, waveguide dimensions, and allowable quadratic phase errors in the aperture. The proposed technique has been validated both analytically and experimentally, and should prove very useful for microwave antenna designers.<
