Abstract (en)

[origin: EP1473799A1] The satellite has a transmitting and/or receiving antenna with a transmission and/or reception source. A transmission and/or reception module (R) of the source delivers and/or receives a beam as per a direction defined by selected phase and amplitude values. A processing module (MT) coupled to the module (R) deviates the beam or receiving direction according to another direction selected by variation of the amplitude value. An independent claim is also included for a usage of satellite in Ku and/or Ka frequency bands.
