摘　　要：中心倾斜馈电缝的设计是波导缝隙天线的最后设计环节,由于结构的特殊性精确计算具有一定难度,至今未见报道。文中采用矩量法完成了中心倾斜馈电缝的分析,其中两层矩形波导的交叉角度是任意的,分析中同时计入了波导壁厚的影响和短路面的高次模影响。通过与HFSS仿真结果比较说明文中方法是精确有效的且具有很高的计算效率。The design of centered-inclined feed slot is the last design procedure of a slotted waveguide array antenna. It is a difficult work to accurately analyze the feed slot because of its special structure, so far it has not been available. The characteristics of inclined feed slot in a broad wall slotted waveguide array are analyzed using MoM in this paper. The angle of two rectangular waveguides is arbitrary. The higher-order modes effect of the finite wall thickness and the short circuit plane are simultaneously considered. The comparing results of the proposed method and the HFSS simulator demonstrate that the proposed method is valid and of very high computing efficiency.
