Compact multiband microstrip patch antenna using defected ground structure (DGS)

The 8th European Conference on Antennas and Propagation (EuCAP 2014), 2014
In 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.

Compact Circular Patch Antennas Using Slots And Defected Ground Structure (DGS)

2019 5th International Conference on Advances in Electrical Engineering (ICAEE), 2019
This research paper contains different compact circular patch antennas. Slots of different structure and Defected Ground Structure (DGS) have been introduced on a normal circular patch to achieve compactness. Six compact antennas i.e. Antenna-AA, Antenna-BB, Antenna-CC and Antenna-DD, Antenna-EE and Antenna-FF have been designed with different level of

Compact bandpass filters using defected ground structure (DGS) coupled resonators

IEEE MTT-S International Microwave Symposium Digest, 2005., 2005
This 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.

A Compact Microstrip CP Antenna Using Slots and Defected Ground Structure (DGS)

2019 IEEE Indian Conference on Antennas and Propogation (InCAP), 2019
A 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.

Mutual coupling reduction using defected ground structure (DGS) for array applications

2012 15 International Symposium on Antenna Technology and Applied Electromagnetics, 2012
In 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.

A compact narrow band microstrip bandpass filter with defected ground structure (DGS)

2012 National Conference on Communications (NCC), 2012
In 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.

Combination of defected ground structure (DGS) and dielectric rod in normal mode helical antenna design

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.
