平板缝隙天线的计算机辅助设计

基于边值积分方程方法的小型平面缝隙阵的机助设计方法。这种计算方法是严格的。但即使对于小型阵，计算量也相当大。对小型阵提出缝列与耦合分支分别设计的方法，并给出模型实验结果。实验结果表明，对于一般指标的方阵，这种方法是可行的。对于低分瓣和超低旁瓣阵，尤其大型阵，还需以严格计算代替大量实验，去寻求简化计算的经验方法，建立一种半经验的机助设计方法。

The CAD for a Small-slotted Planar Antenna Array

The computer aided design method bud on boundary integral equation is presented for small slotted planar array.This method is exact but the required calculation is considerably large even if the array is small.The design method for small array,in which the slots and coupling branches are calculated respectiviy, is presentedas well as the experimental results.These experimental results indicate that this method is practical for square arraywith general index. But for the lOw sidelobe and suave-low sidelobe array,especially for huge array, a semi-empirical computer aided design method should be established,which is a simplified empirical method of culculationbased upon the results of exact calculations, instead Of experiments.
