摘要：
A compact tri-band bandpass filter (BPF) using three shorted stub-loaded dual-mode resonators (SSLDMR) is presented. The center frequency and bandwidth of all three passbands can be flexibly controlled by tuning the electrical length of the corresponding resonators and shorted stubs, respectively. Moreover, each passband can be independently adjusted without affecting the other two. A prototype of a tri-band BPF centered at 2.4, 3.5 and 5.2 GHz has been designed and fabricated with six transmission zeros. Good agreement can be found between measured and simulated results.
