A wideband bandpass filter constructed into substrate integrated rectangular waveguide (SIRW) and incorporating spiral compact microstrip resonant cell (SCMRC) is proposed. Design considerations of these two dissimilar structures are introduced separately. A prototype was fabricated and measured. Good agreements are observed between the experimental results and the simulations. The results demonstrate a wide bandwidth of 70.7% (from 8.6 to 18 GHz), and the ripple in the entire passband is less than 2 dB. © 2006 Wiley Periodicals, Inc.
