Zusammenfassung:This paper presents a technique for performance optimization of microstrip bandpass filter based on a multiobjective differential evolutionary algorithm (MO-DEA). The sides of two magnetically coupled open-loop resonators are modeled using contour points and the points are randomly wiggled to alter the structure of the design. This structure has interesting effects on the S parameters of the bandpass filter. The random structure is optimized using the MO-DE algorithm and precisely defined fitness functions. Based on the proposed methodology, a bandpass filter for {\mathrm {2.4}}\mathrm{GHz} is designed and its results are presented in this paper.
