ARCHITECTURE D'ANTENNE A PLUSIEURS SOURCES PAR FAISCEAU ET COMPORTANT UN RESEAU FOCAL MODULAIRE

An MFPB antenna comprises a plurality of RF feeds with four ports and a BFN, the number of feeds per beam being equal to four, and a single structural interface board, covering all of the ports of the RF feeds, and comprising a plurality of through waveguides. The through waveguides are positioned according to a matrix with multiple rows and multiple columns. The RF feeds are grouped into subassemblies that are respectively integrated in various independent cluster sources mounted one beside the other on the front face of the interface board, the ports of the RF feeds of each cluster source being connected to the through waveguides. The BFN is composed of multiple independent linear partial BFNs, mounted side by side on the back face of the interface board, the various ports of the power combiners that are integrated in each linear partial BFN being connected to the through waveguides.
