Abstract (en)
[origin: US6252562B1] An orbiting satellite system with an antenna for re-transmitting to the ground images collected by image capture instruments of the satellite, the antennas having more than one elementary radiating antenna each of which has more than one cord regularly distributed in a helix about a generatrix of revolution and equi-amplitude power supply for the various cords where the axis of the various elementary antenna are parallel and aligned in one and the same plane in which they are spaced regularly apart in that plane. The plane of the antennas is intended to align with, when the satellite is in orbit, the direction perpendicular to the direction of the speed vector of the satellite. The antenna also has a phase shifting power supply which enables the antenna array to carry out electronic steering of the elongate beam generated by the elementary array.
