The invention concerns an active dual-polarization electronically scanning microwave reflector, adapted to be illuminated by a microwave source to form an antenna. The reflector comprises two interleaved waveguide arrays (21, 22), the base of each guide being closed by a phase-shifting circuit producing reflection and phase shift of the wave it receives, one array being designed to receive a polarization and the other array being designed to receive a polarization perpendicular to the former.

La présente invention concerne un réflecteur hyperfréquence actif à balayage électronique à bipolarisation, susceptible d'être illuminé par une source d'onde hyperfréquence pour former une antenne. Le réflecteur comporte deux réseaux de guide d'ondes (21, 22) imbriqués, le fond de chaque guide étant ferme par un circuit de déphasage réalisant la réflexion et le déphasage de l'onde qu'elle reçoit, un réseau étant destiné à recevoir une polarisation et l'autre réseau étant destiné à recevoir une polarisation perpendiculaire à la précédente.
