An antenna system of the phased array type, with a carrier of electrically insulating material and at least two antenna units, which each comprise a receiving device for electromagnetic radiation and of which the receiving device is connected with a time- or phase-shifting circuit. The receiving devices of the antenna units are connected with each other via the time- or phase-shifting circuit through a combining circuit. The antenna units comprise a recess in the surface of the carrier, having on a recess-defining recess surface of the carrier at least partly a layer of electrically conductive material and having at least one focus; wherein the at least one receiving device is located in or near the focus.

L'invention concerne un système d'antennes du type antenne réseau à commande de phase, qui comporte un support constitué d'un matériau électriquement isolant et au moins deux unités antennes qui comprennent chacune un dispositif de réception pour rayonnements électromagnétiques, lequel est relié à un circuit de décalage dans le temps ou de phase. Les dispositifs de réception des unités antennes sont reliés l'un à l'autre par l'intermédiaire du circuit de décalage dans le temps ou de phase, au moyen d'un circuit de combinaison. Les unités antennes comprennent une cavité ménagée à la surface du support, et, sur la surface du support définissant la cavité, une couche au moins partielle de matériau électroconducteur et au moins un foyer, le ou les dispositifs de réception étant situés dans ce foyer ou à proximité de celui-ci.
