Reconfigurable bandstop filter using Defected Ground Structure (DGS)
2013 Saudi International Electronics, Communications and Photonics Conference, 2013The paper presents a new compact reconfigurable bandstop filter using Defected Ground Structure (DGS). The proposed reconfigurable bandstop filter is constructed by employing coupled DGS resonators etched in the ground plane. The bandstop filter consists of symmetrical DGS resonators with a microstrip excitation to obtain a bandstop filter response ...

Analysis and realization of defected ground structure (DGS) on bandpass filter
2014 5th International Conference on Intelligent and Advanced Systems (ICIAS), 2014An end-coupled line bandpass filter (BPF) is proposed and designed by placing defected ground structure (DGS) in the ground plane. DGS is used for its property of miniaturizing the size of microwave filter and also improving the mutual coupling between the resonators.

Tunable Low-Pass MEMS Filter Using Defected Ground Structures (DGS)
Advanced Materials Research, 2013In this paper, fully monolithic tunable millimeter-wave filters using defected ground structures (DGS) are proposed using the CPW-based periodic structures with novel multiple-contact MEMS switches. Millimeter-wave low-pass filters were designed, fabricated, and tested.

A Novel Defected Ground Structure (DGS) Resonator for Bandpass Filters Applications
2007 Asia-Pacific Microwave Conference, 2007This paper introduces new compact bandpass filter using novel defected ground structure. Different coupling configurations and external coupling have been considered here. Different types of feeding arrangement show the different responses of the bandpass filter. Several second and third order bandpass filters have been designed.

Parametric effect of defected ground structure (DGS) on frequency of a bandpass filter
2013 IEEE International RF and Microwave Conference (RFM), 2013A stepped impedance resonator bandpass filter (SIR BPF) is proposed and designed by placing defected ground structure (DGS) in the ground plane. DGS is used for its property of miniaturizing the size of microwave filter and also improving the mutual coupling between the resonators. The proposed dumbbell shaped DGS is used to tune the bandpass filter to

An ultra broadband antenna (UWB) loaded with defected ground structure (DGS)
2011 International Conference on Electronics, Communications and Control (ICECC), 2011In this letter, an ultra broadband antenna (UWB) loaded with defected ground structure (DGS) is presented. The UWB antenna with circle radiation patch is fed with 50Ohm mictostrip line. The DGS structure is introduced to the ground under the feed line and hence the frequency selectivity is also introduced to this UWB antenna.
