Abstract

A new structure of an ultra-wide bandpass filter is considered. An intelligence method of optimization is applied first for synthesis of three-section filter on dual-mode resonators. An area of fractional bandwidth values and values of dielectric constant of the substrate, where synthesis problem for the filter has a solution, is determined theoretically. Experimental results show good agreement with simulated values.
