摘要： A device for controlling radiofrequency beams comprising a set of cells. Each cell comprises a support frame and an excitation element, and emits and/or receives beams in an invariant manner according to the direction of propagation of the beam. The frame is inscribed within a generally tubular shape, oriented along the axis Z of a reference frame, having a cross section of perimeter P, and comprises an entrance, an exit and a number N of slots between the exit and a position Zo located between the entrance and the exit. Each slot has a variable width along Z. The slot width has a minimum value at the position Zo, and a maximum value at the exit that is determined on the basis of the perimeter P and the number N.

摘要： A method for allocating resources in an active multi-beam antenna satellite telecommunications system operating in a given frequency band and for a given coverage area wherein a plurality of user terminals is located, the method includes the steps of: decomposing the frequency band into sub-bands such that, in each sub-band, the beams formed by the antenna are stable for all of the frequencies of the sub-band, determining, for each sub-band, a grid of orthogonal beams making it possible to cover some of the coverage area, defining several subsets of user terminals and allocating, to each subset, one of the grids of orthogonal beams and a pointing direction of this grid so that each beam in the grid points towards at least one of the user terminals in the subset.

摘要： An excitation assembly comprises a symmetrical OMT and two splitters respectively connected to two pathways of the OMT. The OMT comprises a cross junction comprising a central waveguide parallel to an axis Z and four lateral ports oriented in two directions X, Y, the first splitter consisting of an input waveguide and of two output ports coupled to two lateral ports, oriented in the direction X, by respective connection waveguides. The first splitter is located on a lateral side of the OMT, orthogonally to the direction X, and its two output ports are formed one above the other in a lateral wall of the input waveguide, the upper output port being placed facing a first lateral port of the OMT to which it is connected by the first connection waveguide. The difference in electrical length between the two connection waveguides is equal to λ/2.

摘要： A polarizing reflector for broadband antennas includes a flat dielectric substrate, a patch array layer formed by a bi-dimensionally periodic lattice of thin metallic patches along first and second perpendicular directions x, y, and a ground layer. All the patches have a same shape elongated along the second direction y and form electric dipoles when electrically excited along the second direction y. For each row the patches of the said row are interconnected by an elongated metallic strip oriented along the first direction x and having a width c. The geometry of the patch array, the thickness h and the dielectric permittivity εr of the substrate, and the width c of the elongated metallic strips are tuned so that the patch array including the elongated metallic strips induces a fundamental aperture mode and a complementary fundamental dipolar mode along two orthogonal TE and TM polarizations within a single operating frequency band or two separate operating frequency bands, and the differential phase between the two fundamental modes over the single or the first and second frequency bands being equal to ±90° or to an odd integer multiple of ±90°. The polarizing reflector can comprise also a curved substrate and a patch array layer formed by a bi-dimensionally lattice of metallic patches along first curvilinear rows and second curvilinear columns.
