Abstract (en)
[origin: EP2264830A1] The antenna has a reversible reflector (10) with two separate reflecting surfaces (R1, R2) shaped geometrically to respectively cover different geographical zones. Two independent radiofrequency signal sources (S1, S2) are arranged in a fixed configuration and connected to separate radio-frequency supply chains (2, 3) defining different and predefined operating frequency planes (F1, F2). The reflector occupies two deployment positions in which focal points of the surfaces are located at a phase center (5) and another phase center of the sources by two motors (M1, M2), respectively.
