Abstract
The multi-beam former comprises: two stages connected together and intended to synthesize beams focused along two directions in space; each stage comprises at least two multi-layer plane structures (P11, P1Ny), (P21, P2Mx), superposed one above the other; each multi-layer structure (P11, P1Ny, P21, P2Mx) comprises an internal reflector, at least two first internal sources disposed in front of the internal reflector and linked to two input/output ports (27, 26) aligned along an axis (V, V′), at least two second internal sources disposed in a focal plane of the internal reflector and linked to two second input/output ports (25, 28) aligned along an axis (U, U′) perpendicular to the axis (V, V′); the two second internal sources of the same multi-layer structure (P11) of the first stage are respectively linked to two first internal sources of two different multi-layer structures (P21), (P2Mx) of the second stage.
