摘　　要：结合1970年Robert H.Kyle提出的对数周期天线间互耦的分析方法和1973年Hyong K Choe、Charles E Smith提出的对数周期天线分析方法分析了对数周期偶极子天线组阵时单元间的互耦,给出了阵中单元考虑互耦与不考虑互耦影响的电流分布、阵中方向图以及驻波比,并用该方法和Feco仿真软件计算了天线阵方向图,二者较好的一致性表明了该算法的正确性,得到了互耦对天线性能影响的结论。In this paper, mutual coupling in arrays of log-periodic dipole antennas is analyzed based on the analysis method given by Robert H. Kyle in 1970 and analysis method of log-periodic antenna given by Hyong K. Choe and Charles E. Smith in 1973. Then the current distribution, in-place element pattern and SWR are presented when mutual coupling are considered but effects of mutual coupling are not considered. The directional diagram of the antenna array are calculated with the method and simulation software Feco. The correctness of the method was proved by the high consistency of them. Some conclusions about effects of mutual coupling on antenna characteristics were attained.
