本文利用路 -阵方法分析了对数周期偶极天线。采用矩量法分析天线阵网络 ,网络理论分析集合线网络。借助集合线网络、天线阵网络和矩量法分段上电压电流的联系 ,把两个网络有机结合起来 ,给出形式简洁的天线电流分布解 ,并减少了计算量。 In this paper, the log-periodic method is used to analyze the logarithmic periodic dipole antenna. The method of moment method is used to analyze the antenna array network and the network theory to analyze the aggregation line network. With the help of the connection of voltage and current in the assembly line network, the antenna array network and the moment method subsection, the two networks are combined organically to give a simple solution of antenna current distribution and to reduce the computational load.
