Description
The main goal of MOSAIC project consists in the design of an AESA improving the technical and commercial maturity of the antenna architectures proposed in the ESA invention [1] which describes a design and manufacturing method for large sparse phased arrays for geostationary Earth orbit (GEO) satellite. Sparse arrays offer power consumption reduction through a not regular lattice, at the cost of increasing the complexity of the beam forming network (BFN) as well as a not complete filling of the available aperture. The main idea of MOSAIC consists in adopting: a modular structure, based on irregular subarraying [2][3], to simplify the antenna architecture and the BFN as well as to ensure the complete overlay with the tiles modules of the array aperture; a passive beam forming network composed by monolithic components to significantly enhance the simplicity and manufacturability of the entire system and compliant with additive manufacturing [4].
