A Comparative Study of Microstrip Bandstop Filters Loaded With Various Dumbbell-Shaped Defected Ground Structure (DGS)
In this paper, a comparative performance of microstrip filters loaded with various dumbbellshaped defected ground structures (DB-DGS) has been studied in terms of their bandstop characteristics. During this course, a new dumbbell shaped DGS having transmetal slit in the connecting slot of the square head in the ground plane has been proposed. This proposed design provides an improved bandstop r...
متن کاملMicrostrip Antenna Array with I-Shaped DGS
This paper proposed a microstrip antenna array with DGS (Defective Ground Structure). The structure in this work is 2*1 microstrip patch array antenna using substrate with h= 0.762 mm and εr = 3.2. Two triangular-shaped patches are located on opposite side of PCB and spaced 14mm apart by a small ground portion. The proposed DGS of I-shape is placed in the ground plane. It does provide a method ...
متن کاملNovel Periodic Structures for a Slotline : Patch Loaded Slotline
In this Letter, a dumbbell-shaped patch loaded slotline(PLS) is proposed. Like the conventional defected ground structure(DGS) for a microstrip line, we show that the proposed PLS can provide a wide bandstop characteristic in some frequency bands with only one or small number of unit cells. Also, the equivalent circuit model for a unit section is derived from the analysis of the field distribut...
متن کاملAn Equivalent Circuit for Emi Prediction in Printed Circuit Boards Featuring a Straight-to-bent Microstrip Line Coupling
A full-wave analysis of the scattering parameters of a straight-to-bent microstrip line coupling is performed using a FEM technique. The numerical results, showing the influence played by the geometrical parameters of the structure on the electromagnetic coupling, are then employed to derive an equivalent circuit useful to be employed in CAD tools. A third order polynomial approximant useful to...
متن کاملEquivalent Circuit Model of the Slotted Ground Structures ( SGSs ) Underneath the Microstrip Line Hung
In this paper, the equivalent circuit model of the slotted ground structures (SGSs) underneath the microstrip line is presented. The slotted ground structures are etched off on the ground plane to provide the stopband over the desired frequency range. The frequency response of the stopband can be determined by the dimensions of SGSs. The interaction between the SGSs can equivalent to a parallel...
