Abstract: Certain UHF electron tubes using the interaction between an electromagnetic wave and an electron beam comprises a delay line made up of periodic elements having an aperture for the transit of said beam, the height of said elements decreasing at the end of the delay line to match said end to the input and/or output connections. The present invention allows to avoid the interception of a certain fraction of the beam by the element part comprised between the aperture and the edge of said element, when said part, at said end of the delay line, is reduced. The improvement relates to UHF electron tubes operating in very short wavelengths.
