Abstract:
1. A method of manufacturing an array antenna comprising: a step of designing an antenna array pattern of an array antenna; and a step of physically manufacturing said array antenna using said designing step; wherein said step of designing said array pattern comprises: (a) determining a continuous or discrete one-dimensional reference aperture, associated to a one-dimensional reference radiation pattern; (b) choosing a reference radiation direction for said reference radiation pattern; (c) computing a cumulative phasorial summation of a field distribution of said reference aperture in said reference direction and representing said summation as a reference curve in a complex plane; (d) determining a polygonal curve constituting a polygonal approximation of said reference curve, subject to predetermined constraints; (e) determining, from said polygonal curve, an array pattern wherein: each side of said polygonal curve is associated to a particular antenna element of the array; the length of each side represents a normalized amplitude of an excitation field associated with the corresponding antenna element; and the angles formed by each pair of adjacent sides correspond to a parameter chosen among:
