In this paper, in order to overcome the coupling and fabrication constraints of microstrip structures, 3 layer stripline structure be introduced and based on impedance steps and microwave coupled lines as impedance inverters and multi mode resonators, new and miniaturized structures are proposed. Using this structure, several 2-6 GHz wideband filters has been designed and simulated, and some effective techniques to reducing virtual resonances and improving slope of filter introduced. Finally, a wideband filter is fabricated and using simulation and measurement, efficiency of method is shown.
