摘要

本文介绍了一种采用玻璃通孔（TGV）技术的复合左右手（CRLH）负载慢波基底集成波导（SW-SIW）滤波器。所提出的基于玻璃的拓扑结构在单层基板中集成了通孔和盲孔，从而实现了 SW 效应。这种微型化策略可与其他微型化技术灵活结合。使用 TGV 技术制备的孔的尺寸是印刷电路板（PCB）的十分之一，这使得玻璃基板在毫米波频段更具竞争力。首先揭示了玻璃基 SW-SIW 的传播特性，与传统的 SIW 腔配置相比，所设计的三阶滤波器的尺寸缩小了 53% 以上。随后，嵌入 SW-SIW 的 CRLH 谐振器表现出与传统并联 LC 单元相反的相位特性。此外，SW-CRLH 谐振器还有助于实现四阶滤波功能，而无需扩大初始三阶滤波器的封装尺寸。此外，具有椭圆函数响应的玻璃基滤波器可以实现传输零点（TZ）的独立调整。作为原型，我们设计、制造并测量了一个四阶毫米波滤波器。实验结果证实了制造工艺的先进性和微型化战略的可行性。

Glass-Based Single-Layer Slow Wave SIW Filter With Embedded Composite Right-/ Left-Handed Resonator

This article presents a composite right-/left-handed (CRLH) loaded slow wave substrate integrated waveguide (SW-SIW) filter using through glass via (TGV) technology. The proposed glass-based topology integrates via holes and blind holes in a single-layer substrate, enabling the achievement of the SW effect. This miniaturization strategy can be flexibly combined with other miniaturization technologies. The size of the holes prepared using TGV technique is one-tenth that of printed circuit board (PCB), allowing glass substrate to be more competitive in millimeter-wave band. The propagation properties of glass-based SW-SIW are revealed first, and the designed third-order filter realizes more than 53% size reduction compared to conventional SIW cavity configuration. Subsequently, the CRLH resonator embedded in SW-SIW exhibits phase characteristics opposite to conventional parallel LC unit. Besides, the SW-CRLH resonator can facilitate the realization of fourth-order filtering function without enlarging the packaging size of the initial third-order filter. Furthermore, the glass-based filter with elliptic function response can achieve independent tuning of transmission zeros (TZs). As a prototype, a fourth-order millimeter-wave filter is designed, fabricated, and measured. The experimental results confirm the advancement of the manufacturing process and the feasibility of the miniaturization strategy.

期刊介绍： The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
