摘要

在本文中，我们描述了使用实编码遗传算法(GA)来设计可重构的双波束线性各向同性天线阵列，该阵列具有离散移相器的相位控制。问题是找到一个固定的振幅分布，在垂直平面上产生两个宽幅对称光束:零相位的铅笔光束和五比特离散移相器的离散相位的平顶光束，激励振幅分布的动态范围比(amax/amin)最小或不最小。

Design of discrete phase-only dual-beam array antennas with minimum dynamic range ratio

In this paper, we describe the use of real-coded genetic algorithm (GA) for design of reconfigurable dual-beam linear isotropic antenna arrays with phase-only control of discrete phase shifters. The problem is to find a fixed amplitude distribution that will generate two broadside symmetrical beams in vertical plane: a pencil beam with zero phases and a flat-top beam with discrete phases of a five-bit discrete phase shifter, with or without minimizing dynamic range ratio (amax/amin) of excitation amplitude distribution.
