双注多翼片加载的角向夹持角度对数曲折线慢波结构
Dual beam multi-vane-loaded azimuthal supported angular log-periodic strip meander line slow-wave structure
摘要
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 5 450 Vand 4 650 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.关键词
