Abstract :
This paper presents a novel design of bandstop waveguide filters with two or three rejection bands, using quarter-wave resonators. Bandstop waveguide filters are designed using printed-circuit inserts realized with single-mode and multi-mode resonators. The filter response is analyzed depending on the parameters of the resonators and their positions on the printed-circuit insert. Various models of dual-band and triple-band filters are developed by employing different combinations of the resonators, as examples of the proposed multi-band filter design.
