  • Excitation device for a dual band ultra-high frequency corrugated source of revolution
    Patent number: 4573054
    Abstract: A device for exciting a corrugated ultra-high frequency source of revolution operating in two remote frequency bands, decoupled mechanically from the source. The device includes two excitation devices corresponding to the two operating bands, placed perpendicularly to each other, at respective distances from the mouth of the source such that the waves which they emit remain canalized in the Rayleigh zone of each device and provide optimum coupling between these device and the source.
