Abstract (en)
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.
Abstract (de)
Um bei einer Antenne den schlanken Linearstrahler (1, 2) elektrisch zu verkürzen, wird in Längsrichtung des Strahlers an einer vorbestimmten Stelle mindestens ein Ferritring (3-6) angebracht.
