本文讨论了卫星通信频段采用电感窗的基片集成波导(SIW)结构的谐波抑制滤波器。该SIW结构由通孔实现，并可与同一衬底上的其他电路集成。在中心频率为12 GHz时，SIW滤波器的插入损耗为2.85 d B，回波损耗为17.57 d B。此外，所提出的SIW滤波器还通过插入低通滤波器(LPF)实现了对20dB到30 GHz以下的谐波的抑制。这种抑制谐波的SIW滤波器可用于卫星通信系统。#2007威利期刊，Inc.微波OPT Technol Lett 50：447-450,2008；在线发表在威利国际科学杂志(www.intercience.wiley.com)上。DOI 10.1002/MOP.23114
In this paper, the harmonics suppressed waveguide filter with SIW (substrate‐integrated waveguide) structure using inductive windows at satellite communication band is discussed. The SIW structure is realized by via‐holes and can be integrated with other circuits on the same substrate. The SIW filter has the insertion loss of 2.85 dB and return loss of 17.57 dB at the center frequency of 12 GHz. Also, the proposed SIW filter has the harmonics suppression under 20 dB until 30 GHz by inserted low‐pass filter (LPF). This harmonics suppressed SIW filter can be used in satellite communication systems. © 2007 Wiley Periodicals, Inc.
