Abstract
A satellite platform includes an array of N antennas (Ai, i=1 to 6) and a beamformer, each antenna comprising the satellite casing and a respective metal strand (i=1 to 6) extending in the plane of the Earth face of the satellite, such that if N>2, the axis of the nth strand on the Earth face of the satellite is obtained by rotation of +2π/N, n=2 to N, of the axis of the (n-1)th strand; the beamformer calculates, as a function of a target directivity and polarization to be implemented by the antenna array, an attenuation and a phase-shift selectively for each antenna and applies, to the electrical signal intended for each antenna, the attenuation and phase-shift calculated for the antenna and delivers the duly adapted signal to the antenna to the associated connector.
