  • Array antenna comprising means to suppress the coupling effect in the dielectric gaps between its radiator elements without establishing galvanic contacts
    Patent number: 8164541
    Abstract: A plurality of three-dimensional radiator elements, each radiator element transmitting or receiving electromagnetic waves by a radiating top side. The radiator elements are arranged so that their radiating top sides are substantially parallel and so that at least one pair of adjacent radiator elements are separated by a dielectric gap between sidewalls, the gap behaving like a waveguide which couples electromagnetic interferences with the electromagnetic waves. The adjacent radiator elements further comprise a structure to suppress the coupling effect without establishing a galvanic contact with its adjacent radiator element.
    Type: Grant

  • Array antenna comprising means to establish galvanic contacts between its radiator elements while allowing for their thermal expansion
    Patent number: 8154457
    Abstract: There is disclosed an apparatus comprising a plurality of three-dimensional radiator elements, each radiator element transmitting or receiving electromagnetic waves. The radiator elements are arranged so that at least one pair of adjacent radiator elements are separated by a gap, which behaves like a waveguide inducing by a coupling effect electromagnetic interferences with the waves. The apparatus includes a portion to establish a galvanic contact between the adjacent radiator elements, so as to suppress the coupling effect, while allowing for the thermal expansion of the adjacent radiator elements.

  • Patch fed printed antenna
    Patent number: 6989793
    Abstract: The disclosure relates to a printed antenna fed by a patch. The printed antenna includes at least one ground plane with a radiating opening in it, this radiating opening being arranged to radiate into the space situated above said ground plane, and a conductive feed patch placed beneath said radiating opening and insulated by a dielectric layer, in such a way that the patch is coupled to the radiating opening in order to feed the radiating opening without parasitic radiation being excited. It also concerns printed antennas with two polarization directions and corresponding antenna arrays.
