Abstract

This two-dimensional array antenna, with transmitter-receiver modules (5i) distributed over the surface of the antenna, and with electronic scanning, of the type with radiating elements (6j) grouped together into waveguides (1i) each associated with a transmitter-receiver module, further includes, arranged in front of this array, an active lens (2) able to create electronic scanning in the plane E of the electric field which it receives, preceded or not preceded by a polarisation-rotating grid (3) according to whether this electronic scanning is in the plane E of the electric field or in the plane H of the magnetic field. Application particularly to radar. <IMAGE>
