Design Method and Application of Multi-mode Corrugated Horn

摘要

This paper presents the design method of multi-mode conical corrugated horn (CCH) which aims to utilize the unwanted mode (EH_(12) mode) but not to restrain it, which can be used for the design of wide-band (or multi-band) corrugated horn. The horn designed has good radiation characteristic, which the maximum cross-polarization (XPI) is below -30dB over the band range from 3.4GHz to 6.65GHz.
