1. An active antenna, comprising:
a passive portion of an antenna array extended at one end by a plate in which apertures are formed,
at least one active assembly for transmitting radiofrequency RF waves, called assembly, through said apertures, each assembly comprising:
a first row of active modules facing apertures of the plate,
a second row of active modules facing apertures of the plate and attached to the first row of active modules,
a beam attached to the plate and held clamped between the first row of active modules and the second row of active modules,
a heat-transfer duct in contact with the first row of active modules and the second row of active modules and jutting out on either side of said first and second rows of active modules,
wherein the beam of an assembly has a bevelled profile cooperating with profiles of the first and second rows of active modules of said assembly to press them against the plate.
