Abstract (en)

[origin: EP0124758A1] 1. An antenna the slim linear radiators of which are electrically shortened by at least one impedance element which is effective at a predetermined location in longitudinal direction, characterised in that said impedance element is constituted by a ferrite ring (3 to 6) mounted on the linear radiator (1, 2), said ferrite ring being made of a material which has its maximum variation of the imaginary component (mu") of its complex permeability at the operating frequency range of the antenna.
