| 摘 要： | 针对角向夹持的角度对数周期曲折线慢波结构,提出了展宽其工作带宽、降低其工作电压的新方法.通过翼片加载技术,可以对慢波结构的色散特性进行修正,从而使得其带宽得到有效展宽.通过数值模拟仿真,得到无翼片加载的慢波结构以及多翼片加载的慢波结构的3 dB带宽分别为2. 5 GHz、3 GHz,工作电压分别为5 450 V、4 650 V.研究表明,翼片加载结构可以有效降低角度对数周期曲折线慢波结构的工作电压,以及展宽其工作带宽.

| 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. |
