Abstract
In this paper, a wideband band pass filter (BPF) with two notches is presented using a substrate integrated waveguide (SIW). The BPF consists of U-shaped slots at the top of SIW with an integrated digital capacitor (IDC). The Wideband BPF has a bandwidth of 9.25 GHz from 5.86 GHz to 15.1 GHz. In the pass band, small U-shape slots are inserted inside the bigger U-shape slots and with the help of lumped capacitors with values of 0.2 pF and 0.4 pF notches are created at 8 GHz and 10 GHz. The proposed BPF with two notch has the insertion loss of 0.5 dB, and a return loss of 10 dB in the pass band, bandwidth of 9.14 GHz from 6.46 GHz to 15.6 GHz.
