In this article, a novel microstrip dual‐passband bandpass filter has been proposed and developed. This filter is composed of two modified short‐circuit quarter‐wavelength resonators with a half‐wavelength stepped‐impedance resonator. Design procedures and theoretical analysis are provided; the prototypical bandpass filter with dual passbands is fabricated and measured as well. Well matched simulated results and experimental data validate the proposed filter. © 2009 Wiley Periodicals, Inc.
