Design of a broadband band-pass filter with notch-band using new models of coupled transmission lines

Abstract

We intend to design a broadband band-pass filter with notch-band, which uses coupled transmission lines in the structure, using newmodels of coupled transmission lines. In order to realize and present the new model, first, previousmodels will be simulated in the ADS program. Then, according to the change of their equations and consequently change of basic parameters of these models, optimization and dependency among these parameters and also their frequency response are attended and results of these changes in order to design a new filter are converged.
