The Use of Defected Ground Structures in Designing Microstrip Filters with Enhanced Performance Characteristics [PDF]
, 2014 Until recently, microstrip filter designs were being done with full metallic ground-plane present on one side of the substrate. The state-of-the-art, however, changed when deliberately created defects in the ground (called Defected Ground Structures or ...

Analysis of DGS filters using π‐circuit model
Engineering Reports, 2020 The design and analysis of two defected ground structures (DGS)‐based filters have been proposed in this article. The first is a multifrequency bandstop filter (BSF) which utilizes a semi‐H defect in the ground plane. This structure is then prototyped on
