| Popis: | In this article, a novel dual-band band-pass filter (BPF) using meandering stepped impedance resonators is proposed, since the advantage of their harmonic frequencies behavior, simple structures, and simple-established design methodology.By selecting proper impedance ration (K) and the length ration (α), a dual-band frequencies responses can be achieved. Using this structure, a dual-band BPF performance at 2.4/5.25 GHz is designed. To improve the selectivity, two stubs are introduced into input/output lines to create another three transmission zeros. Both electromagnetic simulation and measurement results are presented. © 2010 Wiley Periodicals, Inc. Microwave Opt Technol Lett 53:123–125, 2011; View this article online at wileyonlinelibrary.com.
