摘要：
A substrate integrated wave guide (SIW) bandpass filter is proposed in this article, which uses proximity coupling structures and slot loaded quarter SIW resonators to implement a cascaded triplet (CT) filter. Electrical coupling is realized with the novel proximity coupling structure, while the size of a quarter SIW resonator (QSIWR) is reduced by 43 percent, when loaded with a slot. By introducing magnetic cross coupling into the electric main coupling path, a C-Band CT filter is designed, which has a transmission zero at the upper stopband. The measured results show good performance and agree well with the simulated results.
