  • Phase shifter module whose linear polarization and resonant length are varied by means of MEMS switches
    Patent number: 7358915
    Abstract: A phase shifter module (CD), dedicated to a reflectarray antenna, is defined by a characteristic resonant length and, in at least one chosen place, has an MEMS type device (DC, DC?) able to be placed in at least two different states respectively permitting and prohibiting the establishing of a short-circuit intended to vary said resonant length, in order to vary the phase shifting of a wave to be reflected presenting at least one linear polarization.
    Type: Grant
    Filed: March 23, 2005
    Date of Patent: April 15, 2008
    Assignee: Thales
    Inventors: Hervé Legay, Gérard Caille, Alexandre Laisne, David Cadoret, Raphael Gillard
  • Phase shifter module whose linear polarization and resonant lenght are varied by means of MEMS switches
    Publication number: 20050212705
    Abstract: A phase shifter module (PSM), dedicated to a reflectarray antenna, is defined by a characteristic resonant length and, in at least one chosen place, has an MEMS type device (SD, SD?) able to be placed in at least two different states respectively permitting and prohibiting the establishing of a short-circuit intended to vary said resonant length, in order to vary the phase shifting of a wave to be reflected presenting at least one linear polarization.
