本文分析辐射波导与馈电波导正交结构的公共宽面中心馈电斜缝和辐射波导缝隙的耦合效应，根据边界条件和等效原理建立积分方程，利用矩量法进行数值求解，给出计算例子，获得谐振长度和等效网络参量随频率、馈电缝隙倾角、辐射缝的位置和／或辐射波导终端负载的变化关系，并与弧立的馈电缝隙的结果进行对比，理论和实验结果吻合较好。
In this paper, the coupling effect of common wide center feeding slot and radiating slot of radiation waveguide and feeder waveguide is analyzed. According to the boundary conditions and the equivalent principle, the integral equation is established and solved by the method of moment. Numerical calculation is given For example, the relationship between resonance length and equivalent network parameters with frequency, feed gap inclination, radiation slot position and / or radiation waveguide termination load is obtained and compared with the results of arc-fed feed gap. The theoretical and experimental results Good agreement.
