摘　　要：本文分析了两个正交矩形波导之间宽壁上窄槽的耦合特性.缝隙对于主波导为纵向槽,对于耦合波导为横向槽,或者相反,槽的位置是任意的.利用等效原理建立一对积分方程组,采用矩量法将其化成矩阵形式并求解,获得散射场和散射参量.介绍了Ku和Ka波段散射参量随频率变化的数据结果,理论与实验值比较,在Ku波段吻合良好,在Ka波段变化趋势相当.The coupling characteristics of a broad wall narrow slot between two crossed rectangular waveguides are analyzed. The slot is longitudinal in the main guide and is transverse in the branch guide,or in reverse. So the slot position in the both waveguides is arbitrary.The equivalence theorem is utilized to set up a pair of integral equations,which are reduced to matrix form using the method of moments and are solved. And the scattered fields and scattering parameters are obtained. Numerical data on the variation of scattering parameters with frequency in the Ku and Ka bands are presented. Comparison between theory and experimental results in Ku band and the trend in Ka band is in good agreement.
