COMPACT FOLDED SUBSTRATE INTEGRATED WAVEGUIDE CAVITIES AND BANDPASS FILTER

By R. Wang, L.-S. Wu, and X.-L. Zhou

Full Article PDF (417 KB)

Abstract:
In this paper, a folded substrate integrated waveguide (FSIW) cavity is analyzed theoretically. Formulae for the determination of the dimensions of the FSIW cavity have been deduced. To verify the proposed formulae, simulated results are compared with the results of the formulae and good agreement has been observed between them. An example filter working at 8 GHz is designed and fabricated. Good agreement between the simulated and the measured results has been obtained. Result shows the advantage of wide out-of-band rejection and compact size.
