| Research Abstract |
In this study, the synthesis theory and design method of ultra-wideband (UWB) bandpass filters (BPFs) using microstrip multi-mode resonators, stub-loaded resonators, ring resonators, and parallel-coupled transmission line resonators are developed. A number of compact and low-loss UWB BPFs are designed, fabricated, and measured. These filters show wide passband, sharp skirt property, wide stopband with large attenuations, and meet well the UWB spectrum mask issued by the Federal Communications Commission of USA or by the Japanese government.
