Optimization of microstrip filter dimensions by differential evolution algorithm

摘要

In the paper the method of a microstrip filter design for high frequency applications is presented. Definition of design criteria is based on the filter tolerance scheme determination. The design process uses differential evolution algorithm. Main part of the paper describes a creation of cost function and the method of its application in cooperation with the used algorithm. Conclusion of the paper presents a found solution and its comparison with filter designed by commonly used commercial software.
