对于未来的多波束形成天线阵列应用，我们的工业合作伙伴Kaytus Technologies Inc. 有兴趣设计一种新的巴特勒矩阵，用作波束形成器。这种波束形成器将被 用于Kaytus Technologies用于无线通信的波束形成天线阵系统。在这 从这个角度来看，我们在这个项目中提出了设计和开发一种紧凑型印刷宽带和单层 Butler矩阵适用于工作在5.15-5.85 GHz频段的多波束天线阵。在这个项目中， Kaytus技术公司将在整个项目期间为研究人员提供研究支持和指导。 此外，该项目将利用由加拿大资助的先进的射频实验室设施。 创新基金会(CFI)和魁北克政府。 NSERC要求的支持将允许拟议的团队设计和开发紧凑型和 用于未来波束形成天线阵系统的单层巴特勒矩阵。巴特勒矩阵的设计应该是 紧凑，只使用单层衬底，并提供较大的带宽。有了这些特点，建议的 巴特勒矩阵可用于波束形成天线阵系统，以覆盖无线通信 频段从5.15 GHz到5.85 GHz。 为了应对这一挑战，拟议的研究将集中在三个部分：(I)密集的文献综述 将在广泛的巴特勒矩阵上进行，以确定潜在的候选人；(2)设计和 将进行分析，以开发紧凑的宽带Butler矩阵，以及(Iii)原型和 所提出的巴特勒矩阵的表征。所开发的技术将对凯图斯有利 Technologies Inc.和整个加拿大航天工业通过有效地为开发 用于波束形成天线阵的新的宽带巴特勒矩阵。

For future multiple-beam-forming antenna array applications, our industrial partner, Kaytus Technologies Inc., is interested in designing a new Butler matrix that will be used as a beamformer. Such beam-former will be employed in Kaytus Technologies' beam-forming antenna array systems for wireless communications. In this perspective, we propose in this project to design and develop a compact printed 8X8 wideband and single-layer Butler matrix for multi-beam antenna arrays operating in the band from 5.15 to 5.85 GHz. In this project, Kaytus Technologies Inc. will provide research support and guidance to the researcher throughout the project. Furthermore, the project will capitalize on the advanced RF laboratory facility funded by the Canada Foundation for Innovation (CFI) and the Quebec government. The requested support from NSERC would allow the proposed team to design and develop compact and single-layer Butler matrix for future beam-forming antenna array systems. The Butler matrix design should be compact, use only a single layer substrate and provide a large bandwidth. With these features, the proposed Butler matrix can be used in beam-forming antenna array systems to cover wireless communications in the band from 5.15 to 5.85 GHz. To cope with this challenge, the proposed research will focus on three parts: (i) an intensive literature review will be carried out on broad Butler matrices in order to identify the potential candidates; (ii) a design and analysis will be carried out to develop compact wide bandwidth Butler matrix, and (iii) prototyping and characterization of the proposed Butler matrix. The developed technology will be beneficial to Kaytus Technologies Inc. and the Canadian space industry in general by efficiently contributing in the development of new wide bandwidth Butler matrices for beam-forming antenna array applications.
