Design a microstrip antenna with defected ground structure

2015 International Conference on Advanced Technologies for Communications (ATC), 2015
In this paper, a compact design for bandwidth enhancement of microstrip antenna is present. A basic rectangle microstrip is selected to research. The ground element of the proposed antenna is taken in the form of Defected Ground Structure (DGS). The antenna is based on substance Duroid RO4700JXR and is fed by a feeding microstrip line. The results of a

Diamond-shaped microstrip patch antenna with defected ground structure

2017 25th Signal Processing and Communications Applications Conference (SIU), 2017
In this study, a broadband microstrip diamond-shaped patch antenna is designed for broadband communication. The results are presented by simulating microstrip patch antenna at 3.675 GHz and 10.35 GHz frequencies. The antenna was simulated in the frequency range of 1–15 GHz. S11, the input reflection coefficient parameter has a value of −14.63 dB at the

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

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.

Dual of Defected Ground Structure for Coplanar Stripline

IEEE Microwave and Wireless Components Letters, 2018
Defected ground structures (DGS) have been used with microstrip and coplanar waveguide (CPW), but until now no comparable structure has been demonstrated for coplanar stripline (CPS), probably because there is no “ground plane.” This letter introduces a dual of DGS for CPS with dual properties, or it acts as a shunt, series RLC circuit that creates an ...

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.
