MOSAIC is focused on designing and manufacturing large sparse phased arrays for geostationary orbit satellites. Sparse arrays offer reduced power consumption due to their non-regular lattice arrangement, but this comes at the expense of increased complexity in the Beam-Forming Network (BFN) and incomplete aperture filling. The core concept of MOSAIC involves adopting a modular structure based on sub-arrays. This approach simplifies both the antenna architecture and manufacturing processes, as well as streamlining the design and implementation of a simplified BFN. The project includes manufacturing and testing one or more subarray breadboards to validate this cost-effective solution. The phased array antenna will be designed for small GEO satellites to Earth communications where there is a great interest, thanks to the reconfigurability and agile beam capability that phased array technology can enable in this applicative context. The targeted mission for this endeavour is the micro-geostationary satellite being developed by SWISSto12 with support from the European Space Agency (ESA).<\/p>\n\n\n\n
