摘要：

In this paper, a dual-band substrate integrated waveguide filter is proposed for 45.5–52.5 GHz and 60–62.5 GHz band. Dual-band substrate integrated waveguide filter is a three pole filter and with multiple transmission zeros. The substrate integrated waveguide (SIW) is designed by inserting metallic vias along the side walls of the substrate with specific spacing and varying diameter. A parametric study by varying the vias geometry is presented with vias diameter as 0.10, 0.12 and 0.18 mm. The return loss and insertion loss of the proposed filter are better that 15 and 1.18 dB, respectively at 0.12 mm which is the improved result as compared when the vias diameter is 0.10 mm and 0.18 mm. The fractional bandwidth is 8.9 and 4.09% from 45.5 to 52.5 GHz and 60 to 62.5 GHz, respectively. © 2018, Bharati Vidyapeeth's Institute of Computer Applications and Management.
