摘要：
In this article, a lambda/2 U-shaped hairpin resonator was contained in a modified end-coupled microstrip fine. The increase of the sizes of U-shaped hairpin resonator and modified end-coupled microstrip line had no influence on the lower operating frequency and would shift the upper operating frequency to lower values. After finding the best designed Parameters, a miniature dual-band microstrip bandpass filler with three transmission zeros generated in the slop-bands was developed on the MgTa1.5Nb0.5O6 microwave dielectric ceramic substrates. The dual-band filter had the central frequencies of 2.45 and 5.2 GHz and was suitable for the applications in the modern WLAN communication. (C) 2009 Wiley Periodicals, Inc.
