This proposal seeks funds to address a problem of current interest for SKYDEL Solutions, namely designing**and developing multi-band circularly polarized (CP) antennas for global navigation satellite systems (GNSS)**applications covering simultaneously the bands of GPS (L1, L2, L5), Galileo (E5a, E5b, E1, E2, L1), and**GLONASS (L1, L3). Through the ENGAGE Program, a postdoctoral fellow from the Energy, Materials and**Telecommunications Center of the Institut national de la recherche scientifique (INRS) will design and**breadboard a multi-band CP antenna for GNSS applications. Other radiating elements may also be studied if**deemed appropriate. In this project, SKYDEL Solutions 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 the NSERC would allow the proposed team to design and develop multi-band CP antennas with**high gain for future satellite navigation systems operating at different bands.**The main objective of this project is to design and develop a new compact microstrip patch antenna with**circular polarization for GNSS systems. The antenna should provide CP polarization, multi-band operation**and high gain and low axial ratio, while preserving high electromagnetic performance to meet operational**requirements of satellite applications. To cope with this challenge, the proposed research will focus on three**parts: (i) an intensive literature review will be carried out on circularly polarized antennas with multi-band**operation in order to identify the potential candidate for GNSS applications; (ii) detailed analysis including**real time challenges based on space application requirements will be carried out to build multi-band circularly**polarized antennas, and (iii) prototyping and characterization of the proposed antennas. The developed**technology will be beneficial to the SKYDEL Solutions and the Canadian space industry in general by**efficiently contributing in the development of new multi-band CP patch antennas for GNSS applications.

该提案旨在寻求资金，以解决SKYDEL解决方案目前感兴趣的问题，即设计 ** 和开发全球导航卫星系统（GNSS）** 应用的多波段圆极化（CP）天线，同时覆盖GPS（L1，L2，L5），Galileo（E5 a，E5 b，E1，E2，L1）和 **GLONASS（L1，L3）的波段。通过参与方案，来自国家科学研究所能源、材料和 ** 电信中心的一名博士后研究员将设计和 ** 试验一种用于全球导航卫星系统应用的多波段CP天线。如果 ** 认为合适，也可以研究其他辐射元件。在本项目中，SKYDEL Solutions将在整个项目中为 ** 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创新基金会（CFI）和魁北克政府资助的先进射频实验室 ** 设施。NSERC要求的 ** 支持将使拟议的团队能够设计和开发具有 ** 高增益的多波段CP天线，用于未来在不同波段运行的卫星导航系统。本计画的主要目的是设计与发展一种适用于全球导航卫星系统的小型化圆极化微带贴片天线。天线应提供CP极化、多频带操作 ** 和高增益和低轴比，同时保持高电磁性能以满足卫星应用的操作 ** 要求。为了科普这一挑战，拟议的研究将集中在三个方面：（一）将对具有多波段 ** 操作的圆极化天线进行深入的文献审查，以确定全球导航卫星系统应用的潜在候选者; ㈡将进行详细分析，包括 ** 基于空间应用要求的真实的时间挑战，以建造多波段圆 ** 极化天线，以及（iii）所提出的天线的原型设计和表征。所开发的 ** 技术将有利于SKYDEL解决方案和加拿大航天工业，** 有效地促进开发用于全球导航卫星系统应用的新的多波段CP贴片天线。
