Design and realization of microstrip filters with new defected ground structure (DGS) [PDF]
Engineering Science and Technology, an International Journal, 2017 AbstractIn this paper, various microstrip filters, such as bandpass (narrow/wideband) filters, dual band bandpass filter and lowpass filters, are designed with new metal strips loaded defected ground structure (DGS). In this proposed DGS, metal strips are introduced in connecting slot of dumbbell shaped DGS (DB-DGS). This new DGS is an improved version

Comparison of Planar Fractal Filters on Defected Ground Substrate
Radioengineering, 2012 The paper discusses approaches to the reduction of dimensions of planar filters (microstrip ones and coplanar ones). Filter dimensions are reduced by applying the fractal theory to the geometry of a filter, and by the defecting of the ground plane of a ...

Parametric studies on effects of defected ground structure (DGS) for dual band bandstop microstrip filter [PDF]
, 2017 A dual-band bandstop microstrip filter is proposed and designed by using microstrip resonator with Defected Ground Structure (DGS). The DGS are placed in the ground plane to obtain high attenuation of the bandstop filter response.

Slow‐wave CPW resonator with defected ground structure (DGS) for filter applications
Microwave and Optical Technology Letters, 2005 AbstractNovel slow‐wave CPW resonators with defected ground structures (DGSs) in a rectangularly spaced and open‐loop shapes are investigated. These structures have an extremely compact size. The simulations and experimental results verify that these structures provide a size reduction of about 54% as compared to a conventional CPW resonator.
