A short horn with high E-plane directivity
Abstract
The E-plane beamwidth of a small pyramidal horn can be substantially reduced by the addition of parabolic cylinder flanges of the proper focal length. Analysis of this antenna involves both geometrical diffraction theory and conventional aperture techniques. In the numerical and experimental examples chosen the flanges halve the half-power beamwidth without severe bandwidth reduction. Consequently a lightweight compact horn is achieved.
