摘要
根据电磁场辐射理论推导天线辐射的数学模型,利用计算机仿真的方法对初步导出的数学模型中的各个参数进行修正,从而得到一个符合实际天线特性的数学模型是一种简洁和准确的分析方法。利用这种方法能够解决多种天线的数学模型问题。将反射板等效地分解为多个独立的天线单元,建立"接收再辐射"是分析天线反射板作用的重要理论。实验结果证明它是简单、有效地分析反射板辐射性能的理论和方法。
The antenna radiation mathematics model is deduced by electromagnetic radiation theory, and the primary mathematics model parameters are modified by utilizing computer simulation, thus acquiring the antenna radiation mathematic model that accords with the performance of the actual antenna, which is a simple and accurate methods of analysis. The methods can solve the problems of diversiform antenna radiation mathematics model. It is an important theory of analyzing the function of reflector plate to decompound equivalently the reflector plate into sever- al independent antennas and to set up the analytic methods of ＂receiving further radiation＂. Experimental result proves that it is a simple methods and correct theory to research reflector plate availably.
