摘要

本文提出了一种基于人工多模衬底集成波导（SIW）谐振器的低损耗自封装Ka波段LTCC滤波器。两个脊和两个金属带紧密集成在一个SIW腔中，形成人工四模谐振器。由于SIW腔的屏蔽，谐振器实现了高Q因子，这有助于Ka波段滤波器的极低损耗。介绍了一种基于人工多模谐振器的带通滤波器的快速设计方法。还讨论了一种同时准确提取多个谐振模式的所有外部Q因子的简单方法。生成一对传输零点以提高滤波器裙选择性。为了验证，在LTCC工艺上制造了工作在28GHz的滤波器。测量结果表明，毫米波应用中具有0.8dB的低插入损耗。

Low-Loss Self-Packaged Ka-Band LTCC Filter Using Artificial Multimode SIW Resonator

In this brief, a low-loss self-packaged Ka-band LTCC filter is proposed based on an artificial multi-mode substrate integrated waveguide (SIW) resonator. Two ridges and two metal strips are tightly integrated in one SIW cavity to form the artificial quad-mode resonator. Due to the shielding of the SIW cavity, the resonator realizes a high Q factor, which contributes to an extremely low loss of the Ka-band filter. A fast design method for the bandpass filter based on an artificial multi-mode resonator is introduced. A simple approach to accurately extract all external Q factors for multiple resonant modes at the same time is also discussed. A pair of transmission zeros are generated to improve the filter skirt selectivity. For verification, a filter operating at 28 GHz is fabricated on the LTCC process. The measured result shows a low insertion loss of 0.8 dB, which is attracted in millimeter-wave applications.
