Abstract: A steerable microwave antenna includes a resonant cavity comprising a partially reflecting surface (PRS) formed of an array of transmitting-receiving cells (CF2) each of which is adapted for control in transmissivity and directivity and a totally reflecting surface (TRS). A radiating element (RE) laid within the resonant cavity is provided in the vicinity of the totally reflecting surface (TRS) so as to generate microwaves. A circuit (Bx, By) for controlling transmissivity and directivity of each transmitting-receiving cell (CF2) and of the partially reflecting surface (PRS) is further provided. Such an antenna can be implemented as an antenna for Wifi connections and cellular telephone handset.
