摘要

本文介绍了一种加载金属通孔壁的宽带前向波耦合器。所提出的耦合器具有宽带宽的特点。两个通孔壁使偶模和奇模的阻抗匹配良好。此外，所提出的结构可以在较宽的频率范围内保持稳定的相位差，从而产生较宽的带宽。3db耦合器的-1 dB带宽为45% (6.8-10.75 GHz)。与传统的耦合线耦合器相比，该耦合器实现了更宽的带宽。

Wideband forward-wave 3-dB coupler constructed by coupled lines and via-wall structures

This paper presents wideband forward-wave coupled-line couplers loaded with metallic via walls. The proposed coupler features wide bandwidth. The two via walls enable good impedance matching of even and odd modes. Moreover, the proposed structure can remain stable phase difference over a wide frequency range, yielding wide bandwidth. The -1 dB bandwidth of the 3-dB coupler is 45% (6.8-10.75 GHz). Compared with the traditional coupled-line coupler, the proposed coupler achieves wide bandwidth.
