Abstract

The nature of reflectarray (RA) optimization problems is intrinsically multi-target and therefore the use of a multi-objective optimization scheme is particularly convenient, although it can be computationally expensive. In this paper some considerations on the characterization and optimization of a RA are presented. The results of the use of efficient approaches for the modeling of the planar RA or of its elementary components are introduced: all of them tend to improve the numerical efficiency of the optimization procedure, without losing in accuracy. Numerical results are provided for the optimization of a dual layer reflectarray antenna with innovative radiating elements, for use in the base station of the WISPERS Project (Wireless Infomobility System for ultra-light Platforms for Emergency Radio Services), which is based on an innovative Unmanned Air Vehicle (UAV).
基于软计算技术的双层反射天线优化设计
反射阵(RA)优化问题本质上是多目标的,因此使用多目标优化方案特别方便,尽管它的计算成本很高。本文对RA的表征和优化提出了一些考虑。本文介绍了利用有效方法对平面RA或其基本部件进行建模的结果:所有这些方法都倾向于提高优化过程的数值效率,而不损失精度。针对基于新型无人机(UAV)的“超轻型应急无线电服务平台无线信息移动系统”(WISPERS)项目基站,提供了一种具有创新辐射元件的双层反射天线的优化计算结果。
