Two-dimensional multi-beamformer, antenna comprising such a multi-beamformer and satellite communication system comprising such an antenna

摘要

The multi-beamformer comprises two stages connected to each other and intended to synthesize beams focused along two directions in space, each stage having at least two superimposed top and bottom A multi-layer planar structure (P11, P1Ny), (P21, P2Mx), each multi-layer structure (P11, P1Ny, P21, P2Mx) is arranged in front of an internal reflector and an internal reflector ( V, V ′) at least two first internal illumination sources connected to two input / output ports (27, 26) aligned along the focal plane of the internal reflector, At least two second internal illumination sources coupled to two second input / output ports (25, 28) aligned along an axis (U, U ') perpendicular to V, V'); -The first stay The two second internal irradiation sources of the same multi-layer structure (P11) are connected to two first internal irradiation sources of two different multi-layer structures (P21) and (P2Mx) of the second stage, respectively. Is done.
