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.
