Abstract: 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.

Abstract: 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.
