针对超宽带滤波器的插入损耗和选择性问题，提出一种基于折叠枝节加载多模谐振器结构的超宽带滤波器。通过调节谐振器的阻抗比及电长度比，可以控制谐振频率。仿真与实验结果吻合良好，表明采用折叠枝节加载形式，可以使滤波器具有低插入损耗和良好的选择性。通带范围在2.9~10.7 GHz，带内插入损耗优于1 dB，实现相对带宽114%。

A ultra-wideband (UWB) bandpass filter based on the folded stubs loaded multi-mode resonator is proposed. By controlling the impedance ratio and the electrical length ratio of the resonator, all of the resonant modes could be controlled. Both simulated and measured results are in good agreement, demonstrating that the proposed UWB bandpass filter has the performance of UWB passband with good frequency selectivity and low insertion losses. The pass band is from 2.9GHz to 10.7GHz, the insertion losses is better than 1dB, and achieving 114%relative bandwidth.
