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。
The porcklington integral equation of nearly grounded antenna is firstly discussed. Discrete Image Method is adopted for sommerfeld integrals over ground plane. Then , the current distribution and impedance characteristic of LF/MF Grounded Vertical Antenna are accurately analyzed with MOM of numerical integral. For example MF 76 m tower, the results of comparison of measuring value to computing value are 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.
