| 摘 要： | 采用矩量法结合复镜像理论计算了近地水平对数周期天线的阻抗矩阵，利用微波网络理论处理馈源问题，从而得到天线的电流分布，最后采用鞍点法计算了远区辐射场。计算结果与有关文献相吻合，证实了该方法的正确性和通用性。

| Abstract: | In this paper, the method of moments and discrete complex image theory are used to calculate the impedance matrix of the horizontal log-periodic antennas over ground plane. The microwave network theory is applied to deal with the excitation, and then we could obtain its distribution current of the antennas. At last, we calculate the radiation pattern with the saddle-point method. The result obtained is consistent with some literature about it, which confirms the correctness and the universality of this method. |
