外文摘要：This article presents a highly efficient method for substrate-integrated-waveguide(SIW)filters to achieve very wide stopbands.By employing the proposed trisection slots in addition to the bisection slots as the inter-coupling structures,all spurious modes below TE505 of a SIW filter working in the fundamental mode TE101(f0)can be eliminated without requiring additional structure or complex theoretical analysis,without affecting the design of the fundamental passbands,and without degrading the performance of the filters.For verification,two prototype filters are designed,fabricated,and measured with wide stopbands up to 4.15f0 and 4.83f0,respectively.The proposed technique could facilitate the development of high-performance wide-stopband SIW filters for microwave/wireless circuits and systems.
