Abstract

Microstrip filters are widely used in modern microwave communication systems such as Wi-Fi, 5G and satellite navigation. This increasingly broad range of applications implies that the frequency spectrum becomes more and more crowded, resulting in more demanding filter specifications. To meet these design specifications, computationally expensive electromagnetic simulations are often used. To speed up the filter design flow, we introduced metamodels for design optimization and variability analysis tasks. This paper illustrates the advantages of using metamodels in filter design by use of a defected ground structure. The average CPU time of the design process decreases drastically, while achieving accurate results.
基于元模型的缺陷地基结构滤波器的高效设计优化与变异性分析
微带滤波器广泛应用于现代微波通信系统,如Wi-Fi、5G和卫星导航。这种日益广泛的应用范围意味着频谱变得越来越拥挤,从而导致对滤波器规格的要求越来越高。为了满足这些设计规范,通常使用计算成本高昂的电磁模拟。为了加快滤波器的设计流程,我们引入了用于设计优化和变异性分析任务的元模型。本文以有缺陷的地面结构为例,说明了在滤波器设计中使用元模型的优点。设计过程的平均CPU时间大幅减少,同时获得准确的结果。
