摘要

通信网络的最新发展不仅满足了动态需求,还为未来大幅扩展的潜在应用提供了便利。这就要求毫米波元件具有理想的电气特性,如结构紧凑、成本效益高、制造复杂度低等。间隙波导(GW)技术被认为是一种潜在的解决方案,因为它为毫米波应用提供了一种前景广阔的导向结构。本文介绍了一种使用标准波导 WR-15 接口的新型同相功率分配器。所介绍的功率分配器基于陷印间隙波导(TPGW),其设计采用了孔径耦合,以实现稳定的(180^{\circ }\ )相位不平衡。功率分配器和过渡器经过设计和优化,在 50-65 GHz 的理想频率范围内最大限度地降低了输入 WR-15 端口的反射系数。超过 \(-\)20 dB 的深度匹配电平足以在 60 GHz 时获得 29% 的相对带宽。为了验证所提出的功率分配器配置和标准 WR-15 波导的性能,我们开发了一个背靠背模型。此外,还进行了数学分析,以研究背靠背模型与单个功率分压器之间的关系。通过背靠背结构制作了一个拟议功率分压器的原型,以验证其性能,模拟和测量结果之间取得了良好的一致性。

A 60-GHz Out-of-Phase Power Divider with WR-15 Standard Interface Based on Trapped Printed Gap Waveguide Technology

Recent developments in communication networks are catering to dynamic requirements as well as providing facilities for future potential applications that are significantly expanded. This necessitates the emergence of mm-wave components that exhibit desirable electrical characteristics, such as compactness, cost efficiency, and minimal manufacturing complexity. Gap waveguide (GW) technology is being considered a potential solution since it provides a promising guiding structure for millimetre-wave applications. This paper presents a novel out-of-phase power divider using the standard waveguide WR-15 interface. The presented power divider is based on a trapped printed gap waveguide (TPGW), which is designed to employ aperture coupling to achieve a stable \(180^{\circ }\) phase imbalance. The power divider and transition have been designed and optimised to minimise the reflection coefficient at the input WR-15 port within the desired frequency range of 50-65 GHz. A deep matching level of beyond \(-\)20 dB is sufficient to obtain a relative bandwidth of 29% at 60 GHz. A back-to-back model is developed to validate the performance of the proposed power divider configuration and a standard WR-15 waveguide. Furthermore, mathematical analyses are performed to investigate the relationship between the back-to-back model and the individual power divider. A prototype for the proposed power divider through a back-to-back structure is fabricated to validate its performance, and good agreement is achieved between the simulated and measured results.

期刊介绍: The Journal of Infrared, Millimeter, and Terahertz Waves offers a peer-reviewed platform for the rapid dissemination of original, high-quality research in the frequency window from 30 GHz to 30 THz. The topics covered include: sources, detectors, and other devices; systems, spectroscopy, sensing, interaction between electromagnetic waves and matter, applications, metrology, and communications. Purely numerical work, especially with commercial software packages, will be published only in very exceptional cases. The same applies to manuscripts describing only algorithms (e.g. pattern recognition algorithms). Manuscripts submitted to the Journal should discuss a significant advancement to the field of infrared, millimeter, and terahertz waves.
