Abstract

An accurate method of electrodynamic analysis of a multiple-element radiating structure has been considered, which uses standard iteration methods applied to a block system of linear algebraic equations (SLAEs). Formulas for SLAE elements for the case of a thin-wire radiating structure have been derived for various versions of projection functions. A mathematic model of a directional antenna is presented for which numerical simulation is carried out. The convergence of the iteration process in calculating distribution of currents, input resistance, and directional pattern has been studied. The efficiency of the method in the absence of strong coupling between elements is shown to be high.

用迭代法计算多单元辐射结构中的电流

摘要

已经考虑了一种精确的多元素辐射结构电动分析方法，该方法使用应用于线性代数方程 (SLAE) 块系统的标准迭代方法。已经为各种版本的投影函数推导出了细线辐射结构情况下的 SLAE 元素公式。提出了一种定向天线的数学模型，并对其进行了数值模拟。研究了计算电流分布、输入电阻和方向图的迭代过程的收敛性。在元素之间没有强耦合的情况下，该方法的效率被证明是高的。
