波导宽边缝隙辐射特性的研究

本文应用伽略金法研究矩形波导宽边上斜缝隙的辐射特性。根据等效原理和并矢格林函数理论建立了积分方程组,用矩量法将积分方程化为矩阵方程,借助计算机求解数值。这种处理方法近似条件少,所得数值解的精度高,可用于波导宽边上多个辐射缝隙的波导缝隙天线系统和波导窄边斜辐射缝隙的分析中。

STUDY OF RADIATING PROPERTIES FOR A SLOT IN THE BROAD WALL OF A RECTANGULAR WAVEGUIDE

Radiating properties of an inclined slot in the bread wall of a rectangular waveguide is invertigated using Galerkin's method.The problem may be described by integral equations,which are derived from an equivalence principle and dyadic Green's function theories. Moment method is employed to transform the integral equations into a matrix equation,and numerical results are obtained by means of a com- puter.The numerical solutions can be achieved with high accuracy,since few approximate conditions are adopted.Furthermore,the method used in this paper may be applied to the analysis of a multi-slot radiating system in the broad wall of rectangular waveguides for slotted-waveguide antennas and the analysis of an inclined slot in the narrow wall of a rectangular waveguide.
