摘要： A device for controlling radiofrequency beams of a given polarization, the device includes a set of at least one cell, comprising a support frame and at least one interconnection internal to the frame. The frame is inscribed within a prism, having a given axis Z′ and faces connected to one another by edges oriented along the axis Z′. The frame comprises corner elements, each having a rim coincident with an edge and being arranged such that the frame has, on each face, a slot (440-n) extending along the axis Z′. The interconnection comprises inductive rods, each comprising two ends of which a first end is connected to a rim, the second ends being connected to one another at a connection point positioned in the centre of the frame in a plane orthogonal to the axis Z′. Each cell is configured to carry out polarization-invariant transmission and/or reflection of beams.

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 radiating element includes at least two feeding guides and one horn common to at least two feeding guides and having an excitation interface, each feeding guide comprising a port guide and an excitation guide connected to the port guide by a port interface and connected to the common horn by the excitation interface, each excitation guide being flared in the direction from the port interface to the excitation interface, each excitation guide not having an axis of symmetry, the two feeding guides being disposed symmetrically relative to one another.
