摘　　要：基片集成同轴线（Substrate Integrated Coaxial Line,SICL）是一种由基板上下导体板、内导体和金属化过孔阵列构成的集成波导结构,具有低损耗、宽频带、抗干扰、易于集成等优点。本文在基片集成同轴线的基础上提出了一种新型的双L型基片集成同轴互连阵列结构。首先通过仿真将它与传统的微带线和带状线进行了对比,结果表明该结构在损耗、反射以及隔离度方面均表现出优良的特性。然后采用低温共烧陶瓷（LTCC）工艺实现该结构,并通过实验测试了该样品的S参数、隔离性能、眼图及误码率。实验结果表明,在1~40GHz的频率范围内,双L型基片集成同轴互连阵列的耦合度在-40 d B以下,传输速率可达到30 Gbps,具有高速数据传输能力。Substrate Integrated Coaxial Line （SICL） is a kind of integrated waveguide, which consists of substrate layers, top and bottom metallic planes, inner conductor and metallic vias. This is a shielded and non-dispersive waveguide, whose fundamental mode is TEM mode. In this paper, based on the SICL, a new type of double-L-shaped substrate integrat- ed coaxial line structure is proposed. Firstly, it was analyzed along with other multi-channel transmission lines including the micro strip lines and the strip lines by simulation. The comparison shows that the double-L-shaped SICL performs much bet- ter than other structures on loss, reflection and coupling. Then, the new structure was realized with low temperature co-fired ceramics （LTCC） technology. The S parameters, eye diagram and bit error rate are measured through experiments. The measured results show that its coupling is lower than -40 dB with a 1 ~ 40 GHz bandwidth. And the date rate could reach 30Gbps, which exhibits the capability of high speed data transmission.
