SLOW-WAVE STRUCTURE, TRAVELLING-WAVE TUBE AND COMMUNICATION DEVICE

WIPO Patent Application WO/2024/059974

A1

A slow-wave structure, a travelling-wave tube and a communication device, relating to the technical field of vacuum electronics. The slow-wave structure comprises: a conductive housing (11), which is internally provided with a vacuum shielding cavity (11a); planar zigzag slow-wave lines (12), which are located in the vacuum shielding cavity (11a), the planar zigzag slow-wave lines (12) being periodically folded metal strip-shaped lines located in the same plane and extending in a transmission direction (z) of an electron beam; an insulating structural member, which is used for fixedly suspending the planar zigzag slow-wave lines (12) in the vacuum shielding cavity (11a); and a metal ridge sheet (14), which protrudes from at least one inner surface of the conductive housing (11) arranged opposite the planar zigzag slow-wave lines (12). The present application can weaken the dispersion intensity of the slow-wave structure, substantially improves the working bandwidth of the travelling-wave tube, and effectively reduces the working voltage of the travelling-wave tube.
