A device for phase-shifting a radiofrequency signal, includes a first carrier and a second carrier, an input port and an output port for radiofrequency signals, the input port and the output port being formed on the first carrier, the phase-shifting device comprising: a first array of conductive pads that are distributed over the first carrier and run from the input port, a second array of conductive pads that are distributed over the second carrier, the first carrier, the second carrier, the first array of conductive pads and the second array of conductive pads being arranged so as to form a structure for guiding radiofrequency signals of variable length having a rectangular cross section, the first array of conductive pads and the second array of conductive pads being configured such that the length and cross section of the guide structure change, over at least a portion of the path along which the radiofrequency signals propagate through the guide structure, as the second carrier moves relative to the first carrier.

Guided-wave broadband mechanical phase-shifting device

An RF joint rotating about an axis of rotation (Z) includes a number N, greater than or equal to 1, of RF transmission channels, a first, internal surface of symmetry of revolution about the axis (Z) and of RF transmission having a first, internal radius r, and a second, external surface of symmetry of revolution about the axis (Z) and of RF transmission having a second, external radius r, strictly less than the first, internal radius r. The first and second RF transmission surfaces facing one another and rotationally mobile about the axis (Z) are configured through the first and second radii r, r, the geometry of the first and second RF access ports, and the geometry of the first and second RF containment and guidance means, such that: each RF transmission channel Vi, i varying from 1 to N, comprises a first RF rotating waveguide, and the N first RF rotating waveguides are distributed angularly over a predetermined number NC, greater than or equal to 1 and less than or equal to N, of sections of surfaces of revolution about the axis (Z) of the second RF transmission surface, each of the NC sections being situated along the longitudinal axis of symmetry (Z) at a predetermined different level L().
