本文介绍了一种基于基片集成波导( SIW)的低成本高Q值Ku波段谐振器。在SIW谐振器中间加载一个空气腔用于减小介质损耗，基于该原理设计加工了一种空气加载SIW谐振器。其测试结果表明，空气加载SIW谐振器的无载Q值达到1000左右，高于其他平面电路。这种谐振器可以广泛应用于高性能平面滤波器和振荡器的设计中。

A low-cost planar passive resonator in Ku-band based on the substrate integrated waveguide ( SIW) tech-nique is reported. An air box filled in SIW cavity is used to reduce the loss of the medium of substrate. The quality ( Q) fac-tor of the air loaded SIW is designed and fabricated. The measured results show that the proposed air loaded SIW resonator possesses an unloaded Q factor of nearly 1000,which is high among other planar passive resonators. The air loaded SIW re-sonator is a promising element for the design of high-performance microwave filters and oscillators.
