摘要 缺陷接地结构(DGS)是目前应用于微波平面电路小型化设计领域的一种新技术,其构造简单、性能优越,而且易于设计和实现。本文主要介绍DGS结构的滤波特性,重点分析了圆环式DGS的结构参数变化对其频率特性的影响,并且利用电路分析法提取这种结构的等效电路及其参数,最后证明其正确性。 Defected ground structure （DGS） is a new technique used to reduce the size of microwave planar circuits. It is of simple structure and excellent performance and is easy to design and realize. In this paper, the filter characteristic of DGS is introduced, and the influences of the cirque-shaped DGS dimensions on frequency characteristics are discussed in detail. Then the equivalent circuit and equivalent parameters of this structure are extracted, and the validity is verified at last.
