摘要

提出了一种新型的三模带通滤波器(BPF)，该滤波器采用半波长螺旋谐振腔中心负载两个t型开桩。通过奇偶模分析，通过调整螺旋谐振器和t型桩的电长度，可以灵活地控制三模谐振器的一个奇模和两个偶模。为了演示，实现了一个以1.8 GHz为中心通带的三模滤波器示例。

Planar microstrip tri-mode bandpass filter using center-stub-loaded spiral resonator

A new tri-mode banpass filter (BPF) using a half-wavelength spiral resonator center-loaded with two T-shaped open stubs has been presented. Analyzed by the odd- and even-mode method, an odd mode and two even modes of the proposed tri-mode resonator could be flexibly controlled by tuning the electrical length of the spiral resonators and T-shaped stubs. For demonstration purpose, a tri-mode filter example with passband centered at 1.8 GHz has been implemented.
