Study of the Double-Ridged Groove-Loaded Folded Waveguide TWT

提出了一种新型的曲折波导慢波结构:曲折双脊单槽加载波导慢波结构。利用HFSS、CST电磁仿真软件对工作在Ka波段的曲折双脊单槽加载波导行波管进行了模拟计算,得到其高频特性及注-波互作用特性。结果表明,在33GHz可以得到265W的输出功率,增益为37.2dB,3dB增益带宽为6GHz。

In this paper a double-ridged groove-loaded slow-wave structure is presented.The characteristics including the dispersion properties,coupling impedance and the electron beam-wave interaction are simulated by HFSS and CST.The results show that the maximum output power is 265 W,the maximum gain is 37.2 dB at 33 GHz and the 3 dB bandwidth is 6 GHz(30~36 GHz).
