Antenna made of photonic forbidden band materials

A base transceiver station (BTS) is an elementary cell of a wireless communication network. It is an interface between user equipment and the whole network. As a consequence, it needs antennas with variable and steerable radiation diagram.

Our new smart antennas use an innovative cylindric structure made of photonic band gap (PBG) materials. Thus, a unique beam or several simultaneous beams can be directed (direction) and/or shaped (shape). Different beams can also be shaped and switched.

According to its configuration, it enables to provide at least one given opening beam, liable to rotate over 360°. Indeed, in particular for the UMTS network, the antennas should be capable of having a directable shaped radiating beam over 360°, liable to follow a user as he/she moves.

An antenna based on our innovative cylindrical PBG structure enables to follow mobile phones, to modify dynamically the covering zones relative to the requirements of the moment, to give priority to a given sector at the rush hours...
