  title={An Overview on Defected Ground Structure},
  author={Lin Hong Weng and Yin Guo and Xiao Wei Shi and Xiao Qiang Chen},
This paper focuses on a tutorial overview of defected ground structure (DGS). The basic conceptions and transmission characteristics of DGS are introduced and the equivalent circuit models of varieties of DGS units are also presented. Finally, the main applications of DGS in microwave technology field are summarized and the evolution trend of DGS is given.
