摘要
针对现有的一种平面介质杆支撑的曲折线慢波结构,提出了利用翼片加载技术修正色散特性,从而有效扩展其工作带宽的方法。模拟仿真结果显示,多翼片加载的曲折线慢波结构和无翼片加载慢波结构相比,3dB带宽从4.5扩展到5.4 GHz,工作电压由11100降低至10100 V,同时增益和电子效率基本保持不变。
By use of multi-vane-loaded technique,a dispersion characteristics controlment method to broaden bandwidth of a dual beam slow wave structure(SWS)with planar dielectric-rods-support metallic meander line is proposed.The simulation results show that the 3 dB bandwidths of the SWS with and without multi-vane loaded are 4.5 and 5.4 GHz,respectively;and the working voltage with and without multi-vane-loaded are 10100 and 11100 V,respectively.In which the gain and the electronic efficiency remain basically unchanged.
