A two‐pole 900/1800‐MHz dual‐band bandpass filter using microstrip open‐loop resonators is proposed. Dual‐band characteristics are obtained by using the fundamental and first spurious resonance of the resonators. Both the internal and external couplings of the filter are appropriately designed to simultaneously satisfy the dual‐band requirements. The measured filtering characteristics of the designed filter agree well with the simulated responses. © 2006 Wiley Periodicals, Inc.
