This article demonstrates the feasibility of a novel waveguide dual-mode two-way power divider that is based on an evolved junction having a dedicated T-shaped central matching element (scatterer). This scatterer, with matching sections facing all three ports, provides equal power division and routes the two TE₁₀/TE₀₁ orthogonal modes of a square waveguide toward the corresponding output ports. The proposed design is compact, easily scalable and can be cascaded to obtain $2^{N}$ output ports, being $N$ the number of division stages. Moreover, this structure represents the first waveguide dual-mode two-way reactive power divider (three physical ports) reported in the scientific literature. An exemplary has been manufactured showing an 11% relative bandwidth at 12 GHz and less than −50 dB of cross-coupling. Transmission loss and isolation between output ports are in good agreement with electromagnetic (EM) simulations.

新型方波波导双模双向无功功率分配器

本文展示了一种新型波导双模双向功率分配器的可行性，该功率分配器基于具有专用 T 形中心匹配元件（散射体）的进化结。该散射体的匹配部分面向所有三个端口，提供相等的功率分配，并将方形波导的两个 TE ₁₀ /TE ₀₁正交模式路由到相应的输出端口。所提出的设计紧凑，易于扩展，并且可以级联以获得 $2^{N}$ 输出端口，是 $N$ 划分阶段的数量。此外，这种结构代表了科学文献中报道的第一个波导双模双向无功功率分配器（三个物理端口）。已经制造了一个示例，显示 12 GHz 下的 11% 相对带宽和小于 -50 dB 的交叉耦合。输出端口之间的传输损耗和隔离与电磁 (EM) 模拟非常吻合。
