Filter Designs Based on Defected Ground Structures
, 2022 This chapter concentrates on the filter structures using Defected Ground Structures (DGS). Initially, this chapter discusses the limitations of Electromagnetic Band Gap (EBG) structures and the development of DGS structure from EBG structure. DGS is an area of increasing interest in EBG technology.

Compact defected ground structure in microstrip technology
Electronics Letters, 2005 A meander microstrip line with defected ground structure is proposed. Its radiation loss and slow-wave effect are evaluated. The compact configuration presents broad stopband and improved slow-wave characteristics. A good agreement between simulation and measurement verifies the designed circuit.
