In this paper, compact substrate integrated waveguide (SIW) band pass filters (BPFs) incorporated with novel diamond shaped complementary split ring resonator (CSRR) are proposed and analyzed using simulation software HFSS. First single stage SIW BPF is analyzed with face to face orientation of outer ring. Thereafter, a two stage filter is analyzed with similar type of orientation. The filters are simulated using substrate material RT Duroid 5880 with relative permittivity of 2.2 and height 0.508 mm. The proposed two stage SIW BPF exhibits highly selective pass band with center frequency of 8.86 GHz with 3-dB bandwidth of 0.74 GHz. It also exhibits one stop band with rejection peak below -60 dB in close proximity to two transmission poles in the pass band. The two stage SIW filter has better selectivity, bandwidth and stop band performance.
