摘　　要：基于简单易行的传输线模型并结合积分方程法,计及微带天线单元间的传输损耗,构建了幅度加权串馈微带天线阵的非线性方程组,通过LM(Levenberg-Marquardt)方法求解了约束条件下的方程组,获得了串馈加权微带天线阵的设计参数。给出的设计实例表明该设计方法是快速综合微带串馈天线阵的简捷有效方法,理论计算与实验结果吻合。In this paper the non-linear equations for the design of microstrip antenna array in series-fed amplitude weighting is derived based on the principle of combining the simple transmission line model （TLM） and integral equation method in which the transmission loss of the microsttip patch antenna elements is taken into account. The equations with constraint condition are solved by using Levenberg-Marquardt method, the weighted design parameters of the series-fed mierostrip antenna array are obtained. The example is showed that the design method for fast synthesis microstrip antenna array in seties-fed is effective and succinctness, theoretical calculations and experimental results are agreement.
