Abstract
The invention provides an elongate antenna having a radiating portion constituted by an elongate conductor element. The elongate element is machined to include: N dipoles (where N is an integer not less than 2) made up of N rectilinear sections of said element in alignment; and N-1 phase-shifter elements, each phase-shifter element being interposed between two consecutive dipoles, each phase-shifter element having a section of the elongate conductor element folded into a U-shape and having branches which are substantially juxtaposed and which extend in a direction that is orthogonal to the common direction of the dipoles.
