A novel S-shaped electromagnetic band gap (EBG) middling bandwidth bandpass fllter based on substrate integrated waveguide (SIW) was proposed. The fllter was designed based on the band-stop characteristics of EBG by etching difierent dimensional S- shaped on the surface of substrate integrated waveguide. The bandpass fllter with a center frequency at 7.765GHz and relative fractional bandwidth 7.31% shows good bandpass characteristics with frequency band between 7:38 » 7:94GHz, while the insertion loss is less than 1.6dB and achieve middling bandwidth in SIW by EBG and has the advantage of bandpass, low insertion loss, compacted and good selectivity etc.. The good agreement between the measured results and the simulated results demonstrates that the design of this proposed fllter is efiective.
