摘要：
This article presents two dual-band bandpass filters (BPFs) using short-ended resonators with high selectivity.The properties of the proposed stub-loaded short-ended microstrip resonators are analyzed theoretically. In case of uniform short or open stubs, the first two resonant frequencies can be easily controlled within a wide frequency range. Thus, they can be utilized to design dual-band BPFs with flexible passband frequencies. For demonstration, two dual-band BPFs have been implemented. Comparisons of the measured and simulated results are presented to verify the theoretical predications. (c) 2012 Wiley Periodicals, Inc.
