Title (EN) PHASED-ARRAY ANTENNA
(FR) ANTENNE RESEAU A COMMANDE DE PHASE
Abstract:
(EN) A phased-array antenna comprises a plurality of radiating elements, a plurality of modules (110) including phase units for changing the phase of a high-frequency signal to be fed to the radiation elements according to a control signal, and a first substrate (120) that holds the modules uniformly arranged on its surface and supplies a high-frequency signal to the modules. This structure facilitates the manufacture of phased-array antennas.
(FR) La présente invention concerne une antenne réseau à commande de phase comprenant : une pluralité d'éléments rayonnants ; une pluralité de modules (110) comprenant des unités de phase destinées à modifier la phase d'un signal haute fréquence devant être transmis aux éléments rayonnants en fonction d'un signal de commande ; et un premier substrat (120) qui supporte les modules agencés de manière uniforme sur sa surface et transmet le signal haute fréquence aux modules. La structure de l'invention facilite la fabrication des antennes réseau à commande de phase.
