Microstrip bandstop filter using spurline and defected ground structures(DGS)

Proceedings of 2011 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference, 2011
Microstrip filters are widely used in microwave circuit, This paper briefly describes the design principle of microstrip bandstop filter (BSF). A compact wide band high rejection BSF is presented. This filter consists of two parts: defected ground structures filter (DGS) and spurline filter. Due to the inherently compact characteristics of the spurline

Tunable Low-Pass MEMS Filter Using Defected Ground Structures (DGS)

Advanced Materials Research, 2013
In this paper, fully monolithic tunable millimeter-wave filters using defected ground structures (DGS) are proposed using the CPW-based periodic structures with novel multiple-contact MEMS switches. Millimeter-wave low-pass filters were designed, fabricated, and tested.

Analysis and synthesis of defected ground structures (DGS) using transmission line theory

2005 European Microwave Conference, 2005
This paper presents a T-shaped DGS which has a wider range of gap capacitance due to two adjacent conductor strips protruded into the dumbbell-shaped DGS. In addition, this structure is completely analyzed and its design equations are provided using transmission line theory.

Microstrip Antenna with Defected Ground Structure (DGS) for Multiband Operation

2016
In this paper, a microstrip feeding rectangular MPA using DGS structure into ground plane is presented. In the absence of a slot, a conventional rectangular MPA is also considered for confirming the validity of designed antenna. This conventional antenna design was found to resonate on 7.0611 GHz frequency at −23.70 dB return loss. When introducing the

Coplanar waveguide (CPW) defected ground structure (DGS) for bandpass filter application

Microwave and Optical Technology Letters, 2004
AbstractIn this paper, we design and implement a coplanar waveguide (CPW) bandpass filter utilizing defected ground structure (DGS) technology. The CPW DGS technology, which only needs one or a series connection of a few cells to exhibit the bandgap characteristics, can provide the attenuation poles in the upper and lower bands to improve the rolloff ...
