PCT No. PCT/IT91/00044 Sec. 371 Date Oct. 11, 1991 Sec. 102(e) Date Oct. 11, 1991 PCT Filed May 23, 1991 PCT Pub. No. WO91/19332 PCT Pub. Date Dec. 12, 1991.An antenna is composed of a number of subarray radiating elements, with an aperiodic geometry, which assures connections between satellites and between satellites and ground stations. The aperiodic structure makes it possible to eliminate possible interference acting on the connection. The possible presence of the array grating lobes during steering of the array beams in the angular sector of interest is reduced. The presence of a grating lobe within the field of view which can cause interference with another low orbiting satellite is avoided, so as to improve reception quality characteristics. The invention is applicable to microwave antennas and space-borne systems by eliminating the presence of grating lobes in the field of view.
