摘要

本文提出了一种在次太赫兹频率下的12路径向功率分配器。径向分频器基于圆极化TE11 （$\text{TE}_{{11}}^{\text{CP}}$）模式，具有低插入损耗的特点。通过简化$\text{TE}_{{11}}^{\text{CP}}$模式换能器并最小化波导凸缘，功率分压器的直径减小到只有28 mm，高度为17.35 mm。在209-231 GHz频率范围内，测量到的插入损耗平均仅为0.3 dB。输出端口之间的隔离度几乎总是超过10 dB，输入回波损耗优于17.8 dB。

A Low-Loss Sub-THz Radial Power Divider Based on Circularly Polarized TE11 Mode

In this article, a 12-way radial power divider at sub-THz frequencies has been presented. The radial divider is based on circularly polarized TE₁₁ (

$\text{TE}_{{11}}^{\text{CP}}$

) mode and features low insertion loss. By simplifying the

$\text{TE}_{{11}}^{\text{CP}}$

-mode transducer and minimizing waveguide flanges, the diameter of the power divider has been reduced to only 28 mm with a height of 17.35 mm. The measured insertion loss averages only 0.3 dB in the frequency range of 209–231 GHz. The isolation between the output ports almost always exceeds 10 dB, and the input return loss is better than 17.8 dB.
