An ultra broadband antenna (UWB) loaded with defected ground structure (DGS)

2011 International Conference on Electronics, Communications and Control (ICECC), 2011
In this letter, an ultra broadband antenna (UWB) loaded with defected ground structure (DGS) is presented. The UWB antenna with circle radiation patch is fed with 50Ohm mictostrip line. The DGS structure is introduced to the ground under the feed line and hence the frequency selectivity is also introduced to this UWB antenna.

Parametric effect of defected ground structure (DGS) on frequency of a bandpass filter

2013 IEEE International RF and Microwave Conference (RFM), 2013
A stepped impedance resonator bandpass filter (SIR BPF) is proposed and designed by placing defected ground structure (DGS) in the ground plane. DGS is used for its property of miniaturizing the size of microwave filter and also improving the mutual coupling between the resonators. The proposed dumbbell shaped DGS is used to tune the bandpass filter to

Stepped hairpin shape defected ground structure (SH-DGS) study

2007 Asia-Pacific Conference on Applied Electromagnetics, 2007
A 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

2010
This 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 −
