摘要
提出了具有截止圆波导的盒形窗的设计方法,使得盒形窗的尺寸大大缩小,结构紧凑,极大地拓宽了盒形窗的频带。针对这种新型盒形窗的主要结构参数,利用HFSS得出了各个参数对其驻波系数的影响,从而找到了几种较好的结构尺寸,使得它们可以应用在较宽的工作频带,最后对比了计算值、模拟值以及实测值的数据,三者符合良好。
The design and theoretical calculation method of a pill-box window with cut-off circular waveguide is presented in this paper, so the pill-box window can be deflated. The effects of the structure dimensions on VSWR are analyzed using HFSS, and several better structures, which can be used in wider bandwidth, is obtained. Both the theoretical calculation and simulation results are in good agreement with the experimental data.
