缝隙耦合HT对特性的分析

CHARACTERISTICS ANALYSIS OF H-T PAIR COUPLED BY NARROW SLOT

分析了通过窄缝隙耦合的矩形波导Ｈ面Ｔ形接头对（以下简称ＨＴ对）的电气特性．利用等效原理和切向场连续性建立积分方程组，采用矩量法化积分方程为代数方程进行数值求解，获得散射场和等效散射参数．以Ｘ波段标准矩形波导ＨＴ接头对为例进行具体求解和计算，以及实验验证，得到良好结果．

It is concerned with T-junction pair coupled through slot at rectangular waveguide. Agroup of integral equations are set up in accordance with the continuity of fields on surfaceand the equivalence theorem. The method of moment is used to do numerical calculation. As aresult, scattering fields and equivalent parameters are obtained. H--T pair junction of standardwaveguide at X-band is measured, the results are in good agreement with the experiment data.
