A tri-mode bandpass filter using capacitive and inductive source-load coupling

Journal Article

This article presents a compact microstrip bandpass filter (BPF), which consists of a circular tri-mode resonator (CTMR) and two meandering feed lines with both capacitive and inductive S-L couplings to obtain good harmonic suppression and multiple transmission zeros. A prototype of the proposed BPF, centered at 4.1 GHz, has been designed and fabricated. The measured results are in good agreement with the full-wave simulated ones.
