摘　　要：应用有耗传输线理论推出串馈微带阵各阵元电流的递推公式 ,给出了增益和方向图的计算曲线 ,与实验结果比对吻合良好 ,这表明串馈微带阵方向图计算必须计入微带线损耗才有可靠精度。还分析了微带天线阵的阵元数目变化与增益之间的关系 。The recursion formulas of elements current for series fed microstrip arrays are presented by applying the lossy transmission line theory. The results of gain and patterns were compared with experiments results. The identity of both shows that it is necessary to take microstrip lines loss into account to obtain accuracy patterns. The relations between the number of microstrip arrays elements and gain are also analyzed and the curve is presented.
