Steerable Electronic Microwave Antenna
First Claim
1. A steerable electronic microwave antenna, said antenna including at least:
- a resonant cavity includinga partially reflecting surface comprising an array of transmitting-receiving cells of said microwave, each transmitting-receiving cell of said array of transmitting-receiving cells being adapted for control in transmissivity and directivity;
a totally reflecting surface facing said partially reflecting surface, said partially and totally reflecting surface forming thus said resonant cavity;
a radiating element laid within said resonant cavity on the vicinity of said totally reflecting surface and adapted to generate said microwave;
means for controlling transmissivity and directivity of each transmitting-receiving cell and thus of said partially reflecting surface.

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.
