一种基于傅立叶变换法的天线阵综合方法

A Synthesis Method of Antenna Pattern Based on the Fourier Transformation

采用傅立叶变换法对天线阵列进行综合,并用matlab软件进行计算和仿真,得出各阵列单元的电流激励分布和天线阵的方向图。结果表明,傅立叶变换法能很好的逼近实际要求的方向图,并且随着单元数的增加,越来越接近要求的方向图。

In this paper,the authors use the Fourier transformation to analyze and synthesize the antenna array patterns.Besides,the Maltab software is also used in the calculation and emulation.Thus,the excitation current of each antenna and the antenna pattern can be obtained.The simulation results show that the method can approach to the practical required pattern and the larger of the antenna's number is,the closer the approach will be.
