四节介质塞加载圆波导平面相控阵理论分析和优化设计

Optimization Design and Theoretical Analysis of a 4-Layers Dielectric-Plugged Circular Waveguide Planar Phased Array

本文用积分方程法严格分析了四节介质塞加载圆波导平面相控阵,给出了阵列反射系数表达式。在分析基础上进行了优化设计,找到了一个合适的目标函数和优化方法。理论和实验对比结果表明,在整个频带内,大扫描角大致趋近,其它扫描角比较符合。

In this paper, a 4-layers dielectric-plugged circular waveguide planar phased array is analysed rigorously by the method of integral equation and the reflection coefficient of array is given.Based on the analysis a reasonable objective function and the optimazation method for the array design are found. The comparison between the theory and experiment shows that they agree roughly in large scan angle and agree well in other scan angles for the frequecy band.
