在这项工作中，研究了多模干涉设计的二维全介质功率分压器，非常适合使用介质波导。最重要的是，在单个器件中实现了功率划分，而不需要级联多个分压器。这允许设计一个非常紧凑和轻便的功率分配器，很好地适用于介电杆天线阵列。作为所使用技术的概念验证，实现了由Rexolite制成的具有4 × 4输出端口的16路功率分配器，工作频率范围在90至105 GHz之间。对于s参数测量，提出了一种特殊的测量装置，包括模块化引脚探针技术和波导终端的辐射锥度。测量结果与仿真结果非常吻合，在期望频率范围内，所有输出端口的功率分配为- 15 dB。这相当于3db的额外插入损耗。为了证明天线阵列的可用性，基于所提出的功率分配器实现了全介电杆天线阵列。使用该阵列，在97.5 GHz时实现了22.5 dBi增益。
In this work, multimode interference is investigated for the design of a two-dimensional fully dielectric power divider, well suited for the usage of dielectric waveguides. Most important, power division is achieved in a single device without the need of cascading multiple dividers. This allows to design a very compact and lightweight power divider, well applicable for dielectric rod antenna arrays. As a proof of concept for the used technique, a 16-way power divider with 4 × 4 output ports, made out of Rexolite, is realized, working in a frequency range between 90 and 105 GHz. For the S-parameter measurements, a special measurement setup, including a modular pin probe technique as well as radiation taper for waveguide termination, is proposed. The measurements are in good agreement with the simulations with a power split of − 15 dB for all output ports within the desired frequency range. This is equal to an additional insertion loss of 3 dB. To demonstrate the usability for antenna arrays, a fully dielectric rod antenna array is realized based on the proposed power divider. With this array, a gain of 22.5 dBi at 97.5 GHz was achieved.
