Abstract In the current work we have prepared a filter design of the smaller one of the hairpin defected ground structure resonator. We also further studied the resonance frequency which is depend of the resonator according to the length of the coupled lines. We have drawn the coupling coefficient using coupling topologies which are simulated in full-wave electromagnetic simulator., useful design... In the current work we have prepared a filter design of the smaller one of the hairpin defected ground structure resonator. We also further studied the resonance frequency which is depend of the resonator according to the length of the coupled lines. We have drawn the coupling coefficient using coupling topologies which are simulated in full-wave electromagnetic simulator., useful design formulas are proposed for filter synthesis Using curve-fitting technique. To verify the proposed synthesis procedure, an example filter design is performed. We found a strong relation among the actual results and simulation. Read More Read Less

Abstract We in this work, we have made a design for a microstrip filter with the help of the Advanced Design System package. We have employed sodium per sulfate for the etching so as to prepare the filter to be fabricated one-sided FR- 4 sub-strate, Further, we have compared the fabricated filter and the virtually designed one. ...

Abstract Using the image theorem we have prepared bi-isotropic material of Tellegen type for which the expressions for both electric and magnetic scalar potential of the point charge placed in air spherical hollow. It represents a contribution to the electromagnetic analysis of bi-isotropic materials and we have tested the design....
