Ultra-wideband hexagonal MIMO antenna with Defected Ground Structure (DGS)
2015 13th International Conference on Electromagnetic Interference and Compatibility (INCEMIC), 2015In this paper, a compact planar Multiple Input Multiple Output antenna system of size 36 mm × 40 mm with two hexagonal monopole elements with L shaped slots is proposed. The UWB operation is achieved by a semicircular shaped Defected Ground Structure (DGS) and the shape of the DGS is optimized to get good return loss.

Compact multiband microstrip patch antenna using defected ground structure (DGS)
The 8th European Conference on Antennas and Propagation (EuCAP 2014), 2014In this paper a novel design for miniaturization of patch antenna is presented. The proposed design for the miniaturized wide band patch antenna consists of hybrid techniques of H-shaped slot on the patch and defected ground structure. Defected ground structure is formed by cutting a combination of U and L-shaped slots.

Stepped hairpin shape defected ground structure (SH-DGS) study
2007 Asia-Pacific Conference on Applied Electromagnetics, 2007A new shape of defected ground structure (DGS) is introduced. The advantage over conventional dumb-bell shape DGS is, the physical dimensions and frequency response can be directly determined using its equivalent LC circuit. The equations can be extracted from Stepped Impedance Hairpin Resonator (SIHR) low pass filter study. They are similar in term of

New Coplanar Low-Pass Defected Ground Structure (DGS) Filter
2010This chapter presents the design of a new compact low-pass defected ground structure filter (DGS LPF). The proposed structure is based on coplanar waveguide (CPW) lines and λ/4 resonators. The filter provides three transmission zeros within the stop-band and offers bandwidth of 8.3 GHz, namely from 3.1 to 11.4 GHz. The stop-band rejection is more than −

A Compact Microstrip CP Antenna Using Slots and Defected Ground Structure (DGS)
2019 IEEE Indian Conference on Antennas and Propogation (InCAP), 2019A Compact circularly polarized coaxially fed slotted microstrip patch with Defected Ground Structure (DGS) is proposed in this paper. DGS is introduced to increase the effective current path length and miniaturize the antenna. Microstrip patch size is reduced by 40% using the proposed DGS and slots.

Compact bandpass filters using defected ground structure (DGS) coupled resonators
IEEE MTT-S International Microwave Symposium Digest, 2005., 2005This paper introduces new compact DGS resonators and ways to implement intra-resonator and external coupling. Different coupling configurations are considered. These new resonators are then applied to design bandpass filters with Chebyshev or pseudo-elliptic responses. Experimental results are presented to show the performance of these filters.
