Hi-Z, low-Z defected ground structure
Microwave and Optical Technology Letters, 2006A hi-Z, low-Z defected ground structure (DGS) produces wide and deep stopband. This structure is simpler in design and more compact in size compared to conventional bandstop structures. The simulation and measured results show good agreement in 2.6 GHz 20-dB rejection bandwidth at 4 GHz center frequency.

A miniaturized dual-band bandstop filter (DBBSF) is proposed by using T-shaped defected microstrip structure (DMS) and U-shaped defected ground structure (DGS). To verify the design concept, the DBBSF is simulated and fabricated. Compared with other published filters, the proposed DBBSF occupies the minimal normalized area.

Wideband band-pass filter with defected ground structure
2017 IEEE 2nd Advanced Information Technology, Electronic and Automation Control Conference (IAEAC), 2017A new type of wideband band-pass filter based on DGS structure is investigated with simulation in this paper. The filter is based on the SIW structure. In order to obtain advantages of compact structure and good performance, DGS and defected microstrip structure are adopted. The filter has the advantages of small size and easy integration.

Modeling of radiation losses in Defected Ground Structures
2016 IEEE International Conference on Engineering and Technology (ICETECH), 2016Defected Ground Structures are useful in many microwave applications. It suffers with radiation and scattering losses through defect in the ground plane. This paper addresses the origin and model of such losses with various 3D EM simulations. This model will be useful in engineering the EMI and losses due to DGS and other defect based resonators.
