A novel defected ground structure for planar circuits

IEEE Microwave and Wireless Components Letters, 2006
A new compact defected ground structure (DGS) is proposed for the microstrip line. The structure is compact in microstrip line direction. Here, this DGS is used to design a compact low pass filter (LPF) that is at least 26.3% more compact lengthwise than other reported compact structures and has sharper transition knee.

2D defected ground structures in microstrip line

2012 5th International Conference on Computers and Devices for Communication (CODEC), 2012
In this paper, two-dimensional (2D) defected ground structures (DGS) are proposed in microstrip line. The dumbbell structure is added as a unit-cell in a systematic manner in both horizontal and vertical directions to construct the 2D-DGS. This technique best utilizes the area to get very low stop band frequencies.

Modeling of bandpass filter using defected ground structure and defected microstrip structure

Journal of Computational Electronics, 2013
In this present work a novel concept for designing of tunable bandpass filter has been introduced with the help of end coupled microstrip transmission line, defected ground structure (DGS) and defected microstrip structure (DMS). Utilizing this concept, one bandpass filter of 8 GHz center frequency with 30 % fractional bandwidth (FBW) at ?3 dB has been

Design of H-shape Defected Ground Structure

2020 IEEE International RF and Microwave Conference (RFM), 2020
This paper presents the design of an H-shape defected ground structure (DGS). Full EM-wave simulation of the design was carried out by using the Computer Simulation Technology (CST) software. The influence of some DGS design parameters on the resonant frequency was simulated and studied.

A microstrip antenna based on the defected ground structure

2013 IEEE International Conference of IEEE Region 10 (TENCON 2013), 2013
The microstrip antenna is widely used in our life now for its low profile, simple structure, low cost and omnidirectional radiation patterns. But the drawbacks of this kind antenna also sometimes confine their applications, especially the narrow bandwidth. In this paper, a microstrip antenna with the defected ground structure (DGS) is proposed.

Electrically small antenna with defected ground structure

2012 42nd European Microwave Conference, 2012
In this paper, a dumbbell shaped defected ground structure (DGS) is proposed to suppress higher order harmonics of an electrically small antenna. A slot loading technique is applied to a well-know low-profile antenna, the area miniaturization of a semi circular microstrip patch antenna by inserting a number of slits parallel to the radiating edges, is ...

Design of RF switch with defected ground structure

2000 Asia-Pacific Microwave Conference. Proceedings (Cat. No.00TH8522), 2002
A three-pole single throw switch with defected ground structure (DGS) is proposed. The equivalent circuit for the proposed switch structure is derived based on equivalent circuit of newly proposed DGS unit structure. The equivalent circuit parameters of DGS unit are extracted by using the circuit analysis method.

Characterization of interdigital stub with defected ground structure

Microwave and Optical Technology Letters, 2009
AbstractA new scheme with an interdigital line and a defected ground structure for dual‐band operation is dealt with in this letter. The proposed structure is analyzed using a series L‐C resonator model added a parasitic shunt capacitance. The nonlinear phase of this structure is dependent on the dumbbell size of the defected ground.
