A Novel Ridge Substrate Integrated Waveguide Using LTCC Technology to Microstrip Transition

介绍了一种基于LTCC技术的脊基片集成波导(SIW)到微带的过渡结构。将传统脊波导到微带过渡的设计思路,运用于基于LTCC技术的基片集成波导(SIW)到Rogers5880基片微带的过渡设计中,实现了LTCCSIW到Rogers5880基片微带的宽带过渡。从仿真结果可以看出,在25.2GHz到40GHz的频带内,回波损耗S11小于-15dB,插入损耗优于-0.2dB。

A novel ridge substrate integrated waveguide using LTCC technology to microstrip transition is presented in this paper.The design ideas of the conventional ridge-waveguide to microstrip transition are applied to achieve the SIW based on LTCC technology to Rogers 5880 substrate microstrip transition.And it realizes broadband transition.According to the simulated results,its return loss S11 is less than-15dB and insertion loss is better than 0.2dB,over the specified frequency range from 25.2GHz to 40 GHz.
