The theory of corrugated conical horn operating at multi-frequency bands is described,. and a practical corrugated conical horn is constructed. It can operate at three frequency bands (4, 6, 11 GHz) at least. The cross poralization peak level is better than-25 dB at 4, 6 GHz frequency bands, and the amplitude pattern at 11 GHz frequency band is also very good It is shown theoratically and experimentally that the corrugated conical horn operating at multi-frequency bands is the best candidate for multi-frequency band feeds.
