Abstract
In this paper, the transition of the folded substrate integrated waveguide (FSIW) using two substrates is suggested and applied to the bandpass filter. The FSIW has similar characteristics with the SIW and can be reduced the width of the SIW. The transition between the FSIW to the microstrip is designed by using shorted quarter wavelength line. Also, the bandpass filter is designed by using the FSIW and the elliptic lowpass filter of 5 section. Fabricated bandpass filter has the center frequency of 5.75 GHz and the bandwidth of 33.2%. Also, the insertion loss and return loss at the center frequency are 0.63dB and 19.1dB, respectively.
