RF antenna

摘要

The invention provides an elongate antenna. The radiating portion of the antenna is constituted by an elongate conductor element which is machined to constitute: 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 being constituted by a section of said elongate conductor element folded into a U-shape having branches which are substantially juxtaposed and which extend in a direction that is orthogonal to the common direction of said dipoles.
