Resumo

A dual-polarization ultra-wideband feed in the form of a metal four-ridge conical horn with a conical two-layer dielectric insert is proposed and investigated. Electrodynamic modeling and optimization of the transition parameters are carried out using finite element and finite difference methods in the time domain. It is shown that the proposed feed provides matching below the level of -10 dB in the frequency band of 6...40 GHz and the efficiency of a single-mirror offset system of more than 0.5 in the frequency band of 6...30 GHz.
