Abstract

This article presents a dual-band Substrate Integrated Waveguide (SIW) filter using a variable comb shape slot on the top metal surface of the SIW cavity. These comb shape slots create a slow wave effect and the dual cavity produces a dual-band with high selectivity. The proposed filter used Rogers 5880 as a dielectric material with a permittivity(εr) of 2.2 and thickness of 0.508 mm. The simulated results obtained by HFSS 19.1 has two narrow bands at 3.6 and 7.8 GHz with the fractional bandwidth of 10.8% and 8.8% for satellite communication. The insertion loss is less than 0.6 dB and the return loss is better than 15 dB. The size of the filter is 0.88 × 0.44 λg2 mm2.
