摘要: A miniaturized dual-mode ring bandpass filter at 1.45 GHz with a bandwidth of 6% is demonstrated. The perturbation the dual modes realized by pair local ground defects. miniaturization achieved loading peripheral butterfly radial stub structure. 41% factor has been using this method. simulated and measured results are in good agreement.
