摘要Abstract: In this paper, a λ/2 u-shaped hairpin resonator was contained in a modified end-coupled microstrip line. 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 dualband microstrip bandpass filter with three transmission zeros generated in the stop-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.
