【摘要】 本文从反应积分方程入手,利用矩量法计算并分析了存在有耗半空间时,垂直裸线天线和介质包层线天线的特性,提出一种与本文所采用的计算方法相适应的激励源近似模型,在数值计算Sommerfeld型积分时采用了推广后的实轴积分技术,节省了计算时间,文中给出了有关天线电流分布及输入阻抗(导纳)的多组计算结果,并将有关计算结果与实验结果进行了比较,通过对计算结果的分析得到几点可供参考的结论。更多还原

【Abstract】 The moment method is used to compute the current distributions and the input impedances of vertical bare wire antennas and dielectric coated wire antennas in the presence of a conducting half-space.An approximate model of the exciting source is appropriate for the computational method used in the paper is presented. Several numerical results are given and compared with the experimental ones. By analysis of these results, some useful conclusions are drawn.更多还原
