  • Transmit-array antenna comprising a mechanism for reorienting the direction of the beam
    Patent number: 10483651
    Abstract: The present invention relates to a transmit-array radiofrequency antenna comprising: a support; a transmit-array arranged in a plane, called a transmission plane; at least one focal source fixed on the support and arranged at the focal length from the array; and a displacement mechanism for moving the transmit-array, the mechanism being connected to the support and being adapted to translationally move the transmit-array in at least one of the two directions in the transmission plane.
    Type: Grant

  • Antenna and associated measurement sensor
    Patent number: 8044864
    Abstract: An antenna which comprises four elementary IFA antennae, each elementary IFA antenna comprising a ground plane (1), a roof (2), a short-circuit (3) between the ground plane and the roof and an excitation means (4), the four elementary IFA antennae being distributed around an axis (Oz) in a first set of two IFA antennae having substantially equivalent elementary radiations and a second set of two IFA antennae having equivalent elementary radiations, the excitation means (4) of the four elementary IFA antennae being fed by radiofrequency signals of like amplitude whereof the phases follow a law which is substantially progressive in quadrature by rotation around the axis.
