    摘要： A radiating element is provided, for example for array antenna, having stacked resonant cavities of Pérot-Fabry type, of compact structure, a lower cavity being fed by excitation means, the radiating element being characterized in that corrugations are formed substantially below a first earth plane delimiting in its lower part the upper resonant cavity. A radiating element structure of improved compactness is also proposed, whose upper cavity is surmounted by a polarizing radome.

    摘要： A reflector array antenna with cross-polarization compensation including at least one radiating element having an etched pattern dissymmetric with respect to at least one direction X and/or Y of the plane XY of the radiating element, the dissymmetry of the pattern of the radiating element being calculated individually on the basis of a radiating element of the same symmetric pattern along the two directions X and Y, so as to engender a reflected wave having a controlled depolarization which opposes a depolarization, engendered in a plane normal to a direction of propagation, by the reflector array illuminated by a primary source .

    摘要： The invention concerns a multilayer focusing spherical lens (21) adapted to be mounted in a transceive antenna device (1) of a terminal of a remote transceiver system and having a concentric focal sphere (S), the lens including a central layer (21a) and a peripheral layer (21b) having different dielectric constants, each dielectric constant value being determined so that the lens (21) focuses parallel microwave beams towards the focal sphere (S) concentric with the lens. A transceive antenna includes a lens of the above kind and a terminal for transmitting and receiving radio signals to and from at least two remote transceiver systems moving at different points in the field of view of the terminal, said terminal including an antenna of the above kind. The invention applies in particular to systems for transmitting data at high bit rates to and from a constellation of satellites, for public or private, civil or military use.

    摘要： The invention relates to a beam forming network of an active antenna with deployable sub-arrays. According to the invention, the network receives information on deformation of the relative position of two panels. Establishing the coherence of the signals takes account of this information to restore the received signals. The invention also provides a spacecraft including the above kind of network and further provides a beam forming method. The invention also provides a system including a craft of the above kind and at least one beacon transmitter station.
