摘要：
A novel microstrip bandpass filter using a dual-mode square-ring resonator is presented in this paper, in which the input/output microstrip lines are arranged under the square-ring to improve the coupling between the microstrip lines and the square-ring. The filter has been investigated numerically and experimentally. The measured result shows that the filter has a minimum insertion loss of 1.5 dB inside its passband and the out-of-band I-ejection level of below -26 dB. (c) 2006 Wiley Periodicals, Inc.
