In this study, a novel substrate integrated folded-waveguide resonator filter is presented and an aperture coupling between adjacent resonators is introduced, which is characterized using full-wave EM simulations and verified experimentally. A demonstrator of two-pole substrate integrated folded-waveguide resonator filter of this type has been designed, fabricated, and tested. As an example, a two-pole BPF centered at 4.675 GHz with a fractional bandwidth of 7.4% is designed, fabricated, and measured. Simulations and experimental results are presented to validate the design and to show the advantages of this type of filter. The simulated and measured results show an excellent agreement. © 2008 Wiley Periodicals, Inc.
