Yves Commault has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Slot hyperfrequency antenna with a structure of small thickness
    Patent number: 5337065
    Abstract: An antenna having a "suspended stripline" structure with two metal plates encircling a dielectric film is disclosed. In this structure, a channel is made for a feeder of a slot with the end of a central conductor of the line penetrating a cavity whose thickness is approximately equal to that of the channel. The slot is made in the upper wall of the cavity.
    Type: Grant

  • Phased reflector array and an antenna including such an array
    Patent number: 5148182
    Abstract: The present invention provides phased arrays using monolithic technology of diffusions over whole wafers for working in millimetric wave frequency bands. The reflector array includes a plurality of metallizations connected together by diodes whose capacity can be varied. Thus direct control of reactive impedances is obtained. With the metallized strips placed at a distance substantially equal to .lambda./4 from a ground plane, it is possible to control locally the phase of the reflected signal.

    Inventors: Francois Gautier, Yves Commault
  • Inverse cassegrain antenna for multiple function radar
    Patent number: 4253100
    Abstract: Inverse Cassegrain antenna making it possible to use on the one hand the qualities of a conventional fine beam for look-out and tracking functions and making it possible on the other hand to have a widened beam either in the elevation plane or in the bearing plane. According to one embodiment, this antenna is provided with a mirror constituted by two reflector - polarizer elements joined to one another by a hinge which permits the articulation thereof, a remote control device regulating their relative orientation.

  • Transition device between a coaxial line and a wave-guide
    Patent number: 4139828
    Abstract: The invention covers transition devices between a coaxial line and a wave-guide. The central core of the coaxial line enters a transverse partial partition in the wave-guide through an opening in it. The core continues in the wave-guide at the level of the partial partition and promotes the passage from an odd TEM type mode to an even, type TE 10, mode and vice versa.
