摘要

本文提出了一种基于衬底集成波导的双陷波宽带通滤波器(BPF)。BPF由SIW顶部的u形槽组成，带有集成数字电容(IDC)。宽带BPF在5.86 GHz ~ 15.1 GHz范围内的带宽为9.25 GHz。在通频带中，在较大的u型槽内插入小的u型槽，并在8 GHz和10 GHz下创建值为0.2 pF和0.4 pF的集总电容器。该双陷波带在6.46 GHz至15.6 GHz范围内的通带带宽为9.14 GHz，插入损耗为0.5 dB，回波损耗为10 dB。

A Wideband Bandpass Filter using U-shaped slots on SIW with two Notches at 8 GHz and 10 GHz

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.
