A novel four-pole bandpass filter design based on a coupled folded-waveguide (FWG) resonator structure is presented. A fullwave simulator has been employed for designing the filter and extracting the related coupling coefficient of each resonator pair. The proposed filter circuit design has been implemented. It has been found that the experimental results of constructed filter are in close agreement with the simulation and theoretical results. This filter also provides a low insertion loss with a much compact size compared with the conventional cavity filters. The theoretical, simulation and experimental results of the coupled FWG filter are presented. © 2006 Wiley Periodicals. Inc.
