Abstract:A bandwidth broadening and voltage reducing method for the azimuthal supported angular log-periodic strip meander line slow-wave structure has been proposed. By means of the vane-loaded technique to control the dispersion characteristics, the bandwidth of the azimuthal supported angular log-periodic strip meander line traveling-wave tube is expanded effectively. Through numerical simulation, it can be found that the 3-dB bandwidth of the structure without vane and with multi-vane loaded is 2.5 GHz and 3 GHz, respectively. The work voltage of the structure without vane and with multi-vane loaded is 5450 Vand 4650 V, respectively. As the results shown, the bandwidth and work voltage of the angular log-periodic strip meander line slow-wave structure can be expanded and reduced by means of vane-loaded method.
