Design and analysis of defected ground structure (DGS) in normal mode helical antenna
2014 IEEE Symposium on Wireless Technology and Applications (ISWTA), 2014This paper presented a study of a defected ground structure (DGS) which affects the performances of the normal mode helical antenna. Two (2) types of helical antennas have been designed; normal mode helical antenna (NMHA) or conventional antenna and the normal mode helical antenna with defected ground structure. The normal mode helical antennas connect

A general circuit model for defected ground structures in planar transmission lines
IEEE Microwave and Wireless Components Letters, 2005 This paper presents a general circuit model for planar transmission line defected ground structures (DGS) that exhibits multi electromagnetic band gaps or stop bands in frequency responses. The proposed equivalent circuit consists of lumped elements that

A novel Defected Microstrip Structure is proposed, which behaves in a similar way than a conventional unit cell Defected Ground Structure (DGS) concerning band-stop response and selectivity. As a difference from the DGS, the DMS structure frequency response is almost the same when the microstrip length varies.

Sierpinski gasket fractal antenna with defected ground structure (DGS)
2012 International Conference on ICT Convergence (ICTC), 2012This paper presents the design and fabrication of Sierpinski gasket fractal antenna with defected ground structure (DGS) with center frequency at 5.8 GHz. A slot was used as a DGS. The antenna was designed and simulated using Computer Simulation Technology (CST) software and fabricated on FR-4 board with a substrate thickness of 1.6 mm and dielectric ...
