A deployable feed cluster architecture comprises a support and an array of radiofrequency RF sources, each RF source comprising a radiofrequency RF chain and of a radiating element, the RF chain being provided with input/output ports. The architecture comprises a deployable panel that is rotatably articulated about an axis of rotation, the array of RF sources mounted on the panel, the panel being rotatably movable between a first position in which the array of RF sources is stowed on the support and a second position in which the array of RF sources is deployed.

A radiating feed of a structural module comprises a feed horn linked to an RF system via a bent ring to orient the feed horn in a desired direction. The bend of the bent ring has an aperture angle of value predefined individually for each horn as a function of the desired orientation, and a vertex placed in a plane of symmetry of the RF system orthogonal to the plane XY containing the RF system. The RF systems of each radiating feed can then be arranged alongside one another and be incorporated in structural planar subassemblies, reducing the number of parts needed to create the multibeam antenna.
