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

A mobile-beam antenna mounting comprises a supporting base, at least one reflector and a transmission and/or reception feed. The feed is mounted in the mounting so as to be immobile relative to the supporting base and the mounting also comprises a mobile support bearing the reflector, the mobile support being mounted on the supporting base with link means suitable for displacing it about at least one fixed displacement axis passing through the phase center of the feed.

Mobile-beam antenna mounting

A mission-flexibility antenna includes a reflector and at least a first source and a second source of radiofrequency signals, which sources are arranged in front of the reflector, the reflector having a focal point and each source having a phase center, and wherein the sources are independent, fixed and connected to separate radiofrequency feed systems defining different and predefined polarization and/or operating frequency characteristics, and in that it additionally includes means of displacement and orientation of the reflector from a first position in which the focal point of the reflector is placed at the phase center of the first source to a second position in which the focal point of the reflector is placed at the phase center of the second source.
