针对0.22 THz 折叠波导行波管设计了一款高频输入输出结构-盒型窗，并对其进行了理论分析和数值计算，通过 CST2010微波工作室和 Ansoft HFSS11进行模拟仿真验证。这种盒型窗不但降低了加工焊接难度，而且保证了较大带宽。本文得到了0.02 THz带宽，在0.21 THz~0.23 THz范围内反射系数都小于0.08。最终通过加工和实验测试对盒型窗进行了验证，实验测试和理论计算基本一致，满足了0.22 THz折叠波导行波管的需要。

A kind of pillbox output window for 0.22 THz folded waveguide traveling-wave tubes is designed. By through theoretical analysis and numerical calculation in CST2010 and Ansoft HFSS11,this new kind of pillbox output window is verified. This pillbox output window adopts non-standard rectangular waveguide which can not only lower the difficulty of processing,but also increase the bandwidth. The results indicate that,the bandwidth can reach about 0.02 THz,from 0.21 THz to 0.23 THz,under the reflection coefficient<0.08. Some key dimensions which have significant effect on the pillbox output windows are also analyzed,and the tolerance in processing is given. The pillbox output window is validated through fabrication and tests. It proves out that the output window can be used for 0.22 THz folded waveguide traveling-wave tubes.
