提出了一种基于混合基片集成波导和欺骗表面等离子体激元的新型模式复合波导。通过不同的馈电方式，SSPP的奇模和偶模被同时激励，并工作在同一频带。因此，同频模式复用的建议奇-偶模复合波导（OEMCW）实现。分析了OEMCW的设计原理和特点。制作了样机并进行了测试，验证了其传输性能.测试结果表明，该波导可工作在10.3 ~ 18 GHz的双模工作频率范围内，隔离度大于18 dB。
In this paper, a novel mode composite waveguide based on hybrid substrate integrated waveguide and spoof surface plasmon polariton (SIW-SSPP) is proposed. Through different feeding methods, the odd mode and even mode of SSPP are excited simultaneously and operate at the same frequency band. Thus, co-frequency mode multiplexing is achieved for the proposed odd-even mode composite waveguide (OEMCW). The design principle and characteristics of the OEMCW are analyzed in this work. A prototype is fabricated and measured to demonstrate its transmission performance. The measured results indicate that the proposed waveguide can operate from 10.3 GHz to 18 GHz in two modes with the isolation larger than 18 dB.
