摘　　要：Based on the substrate integrated waveguide technology, we present a dual-band frequency selective surface （FSS） with a quasi-elliptic bandpass response. The characteristics of the quasi-elliptic bandpass response are realized by shunting two substrate integrated waveguide cavities of different sizes, with the same slots on both sides of the metal surfaces. Four cavities of different sizes and two slots of different sizes are used to design the novel FSS. Every bandpass response with sharp sidebands is induced by two transmission nulls that are generated by the coupling between the slot aperture resonance and the cavity resonance. The simulation results show that such dual-band FSS has the advantages of high selectivity and stable performance at different oblique incident angles. Moreover, it is easy to fabricate.Based on the substrate integrated waveguide technology, we present a dual-band frequency selective surface （FSS） with a quasi-elliptic bandpass response.
