Mutual coupling reduction using defected ground structure (DGS) for array applications
2012 15 International Symposium on Antenna Technology and Applied Electromagnetics, 2012In this paper, a compact dumbbell shaped defected ground structure (DGS) is applied to reduce the mutual coupling between array elements with 0.47 λ 0 elements spacing. The dumbbell DGS is inserted in the E-plane between the adjacent array coupled elements to suppress the pronounced surface waves.

3GHz hairpin filter with Defected Ground Structure (DGS) for Microwave Imaging application
2014 International Conference on Computer, Communications, and Control Technology (I4CT), 2014This paper represents design of 3GHz hairpin filter with Defected Ground Structure (DGS) for Microwave Imaging application by using Advanced Design System (ADS) software and FR4 substrate. Hairpin filter is one of the most popular microwave filters because of its compactness.

A compact narrow band microstrip bandpass filter with defected ground structure (DGS)
2012 National Conference on Communications (NCC), 2012In this paper, a compact narrow band bandpass filter is proposed with hexagonal dumbbell shaped defected ground structure in ground plane of a 50Ω microstrip line and a closed loop resonator in the conducting strip. This arrangement provides better coupling in pass band.

Analysis and synthesis of defected ground structures (DGS) using transmission line theory
2005 European Microwave Conference, 2005This paper presents a T-shaped DGS which has a wider range of gap capacitance due to two adjacent conductor strips protruded into the dumbbell-shaped DGS. In addition, this structure is completely analyzed and its design equations are provided using transmission line theory.

2014 IEEE 2nd International Symposium on Telecommunication Technologies (ISTT), 2014
This paper investigates on a combination of Defected Ground Structure (DGS) and dielectric rod in the normal mode helical antenna (NMHA) design. The effects of the combination of DGS and dielectric rod to the helical antenna performances were studied. All designs operate at low frequency in the range of the UHF band.
