| 摘 要： | 本文采用矩量法(分段正弦基函数、伽略金法)分析计算了长八木天线各振子上电流分布、输入阻抗、增益及方向性图等特性。并以长八木天线增益为优化目标,采用单纯形法对天线的振子间距进行了优化。最后计算长八木天线在一定频带内的增益曲线。所得结果与实验结果吻合较好。

| Abstract: | The Moment Method is used to analyse and calculate the properties of a long Yagi-Uda array. For example, the distribution of current along a dipole element, input impedance, gain and pattern etc. and the maximization of the gain of a 25 elements Yagi-Uda array are obtained by adjusting the space between dipole elements using the simple optimization procedure. The gain in a certain band of frequency is also calculated which shows good coincidence with the experimental results. |
