波导宽边中心倾斜孤立辐射裂缝的分析

本文首先建立波导宽边中心倾斜孤立辐射裂缝的积分方程，然后用矩矩量法求解得到了孤立的Ｓ参数及归一化等效阻抗。在积分方程的求解中，将三重积分化为二重积分，既 三重积分计算时间长，精度和收敛性差的缺点，又不致于使表达式过于重复和杂。本文分析计算所得到的裂缝特性参数可以用于波导宽边中心倾斜裂缝阵的设计。

波导宽边中心倾斜孤立辐射裂缝的分析

In this paper we use the moment method to analyze the characteristics of an isolated centered inclined slot on the broad face of a rectangular waveguide. Then we derive the scattering, matrix and the. equivalent impedance formulas. There are several triple integrals in the elements of admittance matrix. During numerical integration the triple integral is time consuming and divergent when the number of higher waveguide medes increases. Thus, we use an appropriate methed to reduce the triple integrals to double integrals, which are convergent, time saving and have better accuracy during numerical integration.The characteristic paramters obtained in this paper may be used to design a centered inclined slot array.
