Abstract:High-power corrugated horn acting as the feed of satellite and earth station antenna is needed more and more. The structural composition of a Ka/EHF dual-band corrugated horn is described. The formula and parameters of slots for each section of the corrugated horn are given in detail. Finally, the values of reflection loss and normalized radiation pattern of the corrugated horn are calculated by Champ software and are tested in the microwave darkroom respectively. The result of calculation is consistent with the result of experiment.
Keywords:Ka/EHF dual-band  mode converter  circle transition  corrugated horn
