摘要
利用矩量法对矩形波导端头裂缝的散射特性进行了理论计算，讨论了缝的谐振频率与缝长、缝宽、壁厚等的关系，并给出了测试结果．计算磁流分布表明：基模占主导地位，三次模的幅度为主模幅度的５％以下，缝隙口面的场分布为对称分布．
The radiating slot in the end wall of a rectangular waveguide is analyzed using the moment method. The relationship between resonant frequency and slot length, slot width, and slot depth has been discussed. The measurement result of VSWR as a function of frequency is given. This paper has laid the foundation for the analysis of the phase array which uses the slot in the end wall of the rectangular waveguide as a radiator unit.
