Analysis of a new corrugated guide feed horn having dual‐depth corrugations

Abstract

A new corrugated guide horn having dual‐depth corrugations was proposed by Carpenter and Ghosh in 1980. It is attractive for achieving improved performance over a wide band or a multiband. In this paper a space‐harmonic analysis has been made, the relation between the fields in the adjacent slots of the dual‐depth corrugations has been found, and the eigenvalue equation and the formulae of the equivalent admittance have been established. As an example, the predicted performances of a new multiband horn have been given.
