Abstract
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.
