摘要

提出一种窄带基板集成波导(SIW)双模方腔带通滤波器。在谐振腔中引入两个感应扰动金属圆柱体来调节谐振频率、带宽和带外抑制。制作了一台样机并进行了测量，结果与仿真结果吻合较好。在回波损耗为-15 dB时，谐振频率的导数仅为0.3%，带宽约为3.5%。

Tunable Substrate-Integrated Waveguide (SIW) Dual-Mode Square Cavity Filter with Metal Cylinders

One narrow-band substrate-integrated waveguide (SIW) dual-mode square cavity bandpass filter is proposed. Two inductive perturbation metal cylinders are introduced into the cavity to tune the resonant frequencies, bandwidth and out-of-band rejection. One prototype was fabricated and measured, good agreement between the measured and simulated results are observed. The derivation of the resonant frequency is only 0.3%, the bandwidth is about 3.5% at -15 dB return loss.
