波导缝隙阵列天线的改进设计

内容简介：针对天线E面远区副瓣电平抬高现象对天线进行改进设计,寻求改善方向图E面远区副瓣电平的方法。通过建立辐射阵面的数学与物理模型对阵面幅度分布进行微调,最后利用遗传算法对阵面辐射单元进行优化,解决了方向图E面远区副瓣电平抬高的工程应用问题。

Abstract：In this paper,we want to improve the design of the antenna for in the antenna E-plane far field sidelobe level phenomenon,seeking to improve the E-plane far field sidelobe level of directivity.Fine-tuning through the establishment of the mathematical and physical models of the radiation front against the surface amplitude distribution,finally uses the genetic algorithm against the surface of the radiating element to optimize,and solves the problem of the engineering applications of E-plane directivity far field sidelobe level.
