Claim Text:
1. A multibeam transmitting and receiving antenna with multiple feeds per beam comprising at least one reflector and one array of several feeds illuminating the reflector, the feeds being clustered into several groups offset with respect to each other in two directions X, Y of a plane, each feed comprising a radiating element connected to a radiofrequency channel, wherein: each feed comprises a first and a second transmitting port having a same transmission frequency and orthogonal polarizations to each other and a first and second receiving port having a same reception frequency and orthogonal polarizations to each other, the reception frequency being different from the transmission frequency, the feeds are clustered by groups of four adjacent feeds in the directions X and Y, for each group of four adjacent feeds, the first or the second transmitting ports, and the first or the second receiving ports, corresponding to a same frequency and to a same polarization are connected two-by-two in the direction X then two-by-two in the direction Y, the four interconnected transmitting ports forming a transmitting beam and the four interconnected receiving ports forming a receiving beam.
