TLDR
In this article, the diffracted far field of a wide-flare-angle corrugated conical horn (operating on the HE11 mode) has been obtained making use of a simpler expression for the aperture field.Abstract:
Expressions for the diffracted far field of a wide-flare-angle corrugated conical horn (operating on the HE11 mode) have been obtained making use of a simpler expression for the aperture field. Expressions for the radiation pattern and gain reduce to a closed form when the flare (semivertical) angle is less than 30°. The theoretical results are in close agreement with experiment.read more

Shielding effectiveness of corrugations in corrugated horns
TL;DR: In this paper, the current density on the walls of corrugated dihedral horns is evaluated as a function of such corrugation parameters as the tooth density, and the ratio of the gap to the period (of the corrugations).

Corrugated conical horn as a space feed for phased-array illumination
TL;DR: In this article, the importance of corrugated conical horns in space-fed illumination of phased arrays is indicated, and design details pertaining to corrugation of conical horn of optimum proportions for uniform illumination of a phased array with a prescribed area are presented.

An offset reflector antenna with low sidelobes
TL;DR: The corrugated conical horn is considered to be an ideal feed for low sidelobe reflector antennas because of its unique characteristics as discussed by the authors, and it has been shown that low flare horns are preferred over high flare horns to give rise to low sidelobes performance for a given offset reflector antenna system.

Radiation properties of conical scalar horns
M.S. Narasimhan,B.V. Rao +1 more
TL;DR: In this article, it was shown that the eigenvalues derived in a closed form from a simpler solution associated with balanced hybrid modes in conical scalar horns are close (within 4%) to the exact values obtained numerically by Clarricoats for the first ten modes.
