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.
