Active Polarizing Cell, Transmitting Array, and Radio Transmitting and Receiving Antennas. The invention relates to a polarizing cell (C) configured to receive incident radiation on one side of the cell and to produce, from the incident radiation, on a second side of the cell opposite the first side, re-emitted radiation having circular polarization. The cell includes a switching mechanism (15) configured to produce, in a controlled manner, a first active phase shift of the incident radiation. Such a cell can be used in a reconfigurable transmitting array, in particular for use in the construction of a radio transmitting or receiving antenna. A beamforming and scanning function can be achieved by controlling the active phase shift in each cell of the transmitting array. Figure for the abstract: Fig. 2
