| 摘 要： | 首先推导出了近地直立天线的porklington积分方程,采用基于分析近地天线问题的索莫菲积分方程的离散复像法,通过数值积分矩量法精确分析了长、中波直立接地天线的电流分布与阻抗特性。以76 m高的中波塔为例,通过实测值与计算对比,验证了该方法求解低频天线特性的准确性,为此类天线在工程设计中提供了更精确的计算机数值分析设计方法。

| Abstract: | The porcklington integral equation of nearly Grounded Antenna is firstly discussed. Discrete Image Method of is adopted for sommerfeld integrals over ground plane.Then ,the current distribution and impedance characteristic of LF/MF Grounded Vertical Antenna is accurately analyzed with MOM of numerical integral.For example MF 76m tower,the results of comparison of measuring value to computing value is presented which show that the method is precise.Therefore the more precise method is offered for designing LF/MF grounded Vertical Antenna in the engineering . |
