| 摘要: | 本文介绍了基板集成波导(SIW)H平面T型双工器的严格模态分析. 该分析基于用于波导T型结问题的经典耦合矩阵技术. H平面T型结不仅将两个SIW滤波器连接在一起, 而且还用作两个SIW滤波器的公共端口和第一级之间的耦合结构. 首先推导了H平面T型的设计方程, 然后设计, 加工并测试了一个工作在X波段的4阶原型双工器. 双工器的实测通带中心频率分别为9.03和9.42GHz. 同时, 测试结果与预测结果具有很好的一致性. |
| Abstract: | A rigorous modal analysis for the substrate integrated waveguide (SIW) H-plane T-junction diplexer is presented in this paper. The analysis is based on the classical coupling matrix technique for waveguide T-junction problems. The H-plane T-junction not only connects the two SIW filters together but also acts as a coupling structure between the common port and the first stages of the two SIW filters. The design equations of the H-plane T-junction are first derived, and then a 4-order prototype diplexer working at X-band is designed, fabricated, and measured. The measured centre frequencies of the pass-bands of the diplexer are 9.03 and 9.42GHz, respectively. Meanwhile, the measured results are in good agreement with the predicted ones. |
