Abstract
A dual polarization active microwave reflector with electronic scanning, configured to be illuminated by a microwave source to form an antenna. The reflector includes two imbricated waveguide arrays, the bottom of each waveguide array being closed by a phase shift circuit carrying out the reflection and the phase shifting of the wave that it receives. One of the two waveguide arrays is configured to receive a first polarization and the other waveguide array is configured to receive a polarization perpendicular to the first polarization.
