摘要
基于对数周期偶极天线阵分析的需要 ,提出了一种将矩量法和LPD天线的等效传输矩阵网络相结合的迭代方法 ,并用该方法对自由空间单根 13单元的对数周期偶极天线进行了分析计算。将计算结果与假定各阵子电流为一项式分布的经典等效电路法所得结果进行了对比。
Based on the need for the analysis of the log periodic dipole antenna (LPDA) array, an iteration method for analyzing the LPDA is presented. The method of moments (MoM) and the equivalent transmission matrix network of the antenna are properly integrated. An LPDA with thirteen elements is analyzed. The results are compared with the calculation results by using the equivalence circuit method with predicted sine distribution current along each element. The results of comparison are presented, which show that the new method is precise.
