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