摘要
本文提出了一种易于在PC机上实现的用于分析和计算圆柱共形微带天线特性的新方法 .基于矩量法 ,提取出广义阻抗矩阵和电压矢量元素中快速振荡及慢收敛部分 ,利用非线性逼近方法将矩阵元素写成闭合形式 .这种新方法的使用使得天线输入阻抗和方向图的计算效率大幅度提高 ,通过与已有文献中算例的比较 ,证明了本文方法的正确性和高效性 .
A new method which can be easily implemented on PC is presented for analyzing the characteristics of cylindrically conformal microstrip antennas.Based on the method of moments (MOM),the fast oscillatory and slowly convergent parts of the generalized impedance matrix and voltage vector elements are extracted,then these elements are cast into closed-forms by using the nonlinear approximation.By using this method,the computational efficiency is improved dramatically.Compared with the published results in the corresponding references,the correctness and high efficiency of this method are verified.
