DEVICE FOR CONTROLLING RF ELECTROMAGNETIC BEAMS ACCORDING TO THEIR ANGLE OF INCIDENCE, AND MANUFACTURING METHOD

The invention proposes a device (10) for controlling radiofrequency beams comprising a set of cells (100). Each cell comprises a support frame (130) and an excitation element (150), and emits and/or receives beams in an invariant manner according to the direction of propagation of the beam. The fram...

Zusammenfassung:The invention proposes a device (10) for controlling radiofrequency beams comprising a set of cells (100). Each cell comprises a support frame (130) and an excitation element (150), 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 (X,Y,Z), having a cross section of perimeter P, and comprises an entrance (131), an exit (132) and a number N of slots (133-n) 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.
