Multiband multibeam antennas for cryogenic cooled satellite ground stations

该项目旨在开发一种用于多卫星通信的紧凑型多频段天线阵，特别是一种可在同一口径内同时工作在S(2 GHz-4 GHz)和X(8 GHz-12 GHz)频段的天线系统。该项目将克服传统地面站中单一卫星连接的局限性，利用多个波束同时向多颗卫星提供下行链路。这项研究将直接应用于Quasar卫星技术公司的下一代卫星地面站产品，Quasar卫星技术公司是一家澳大利亚初创公司，提供卫星地面站即服务(GSaaS)。这将给社会带来巨大的好处，因为它能够快速、负担得起的卫星数据访问，为社区和紧急服务提供服务。

The project aims to develop a compact multiband antenna array for multi-satellite communication, particularly an antenna system that operates in both S (2GHz-4GHz) and X (8GHz-12GHz) bands in a shared aperture. This project will overcome the limitations of single satellite connectivity in legacy Ground Stations by providing simultaneous downlinks to multiple satellites using multiple beams. The research will directly apply to the next-generation satellite Ground Station product of Quasar Satellite Technologies, an Australian startup providing satellite Ground Station as a Service (GSaaS). This will have enormous benefits to society as it enables fast, affordable satellite data access for services to communities and emergency services.
