Abstract (en)
[origin: WO2009083513A1] The invention relates to an array antenna (ANT) comprising radiating elements (ELT) distributed in subarrays (SR1, SR2, SR3, SR4), the subarrays being supplied via substantially identical amplifiers (AMP1, AMP2, AMP3, AMP4) operating at identical levels. The radiating elements (ELT) of a given subarray are distributed non-uniformly in space, the distance between two adjacent radiating elements being a function of the illumination law desired for said array antenna and of the technical characteristics of the subarrays (SR1, SR2, SR3, SR4).
