Investigation on a defected microstrip structure and applications in designing microstrip filters

Journal of Electromagnetic Waves and Applications, 2012
A new defected microstrip structure is proposed in this paper. By etching a simple U-shaped slot in the center of microstrip line, a very good bandstop characteristic is exhibited. Its resonant frequency is extracted by transmission line network analysis.

Analysis of microstrip bandstop filter characteristic based on defected microstrip structure

2017 Progress In Electromagnetics Research Symposium - Spring (PIERS), 2017
Defected microstrip structure (DMS) has similar characteristics to DGS, such as slow-wave characteristic and rejecting microwaves in certain frequencies, which has been applied in microstrip bandstop filter design to obtain good stopband property and decrease the size of the microstrip filter.

Microstrip bandstop filter using G-shaped defected microstrip structure

2017 Progress In Electromagnetics Research Symposium - Spring (PIERS), 2017
In recent years, many scholars have used defected microstrip structure (DMS) to design the notch fllter, which has similar characteristics to DGS, such as the properties of slow-wave, rejecting microwaves in certain frequencies and decreasing the size of the microstrip fllter.

A New Microstrip UWB Bandpass Filter Using Defected Microstrip Structures

Journal of Electromagnetic Waves and Applications, 2010
This paper presents a new ultra wideband bandpass filter which is implemented using defected microstrip structures (DMS). This wideband bandpass filter consists of a cascade connection of new bandpass DMS resonators. Transmission line model for proposed resonator is introduced, and detailed analysis using method of lines is investigated.

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.

Compact microstrip lowpass filter based on defected ground structure and compensated microstrip line

IEEE MTT-S International Microwave Symposium Digest, 2005., 2005
An improved defected ground structure (DGS) with compensated microstrip line is investigated for low-pass filter (LPF) applications. With this structure, the basic resonant element exhibits the elliptic-function low-pass responses. The use of introduced resonant elements allows sharp cutoff frequency response and high harmonic suppressions together ...
