Abstract

L'invention concerne une antenne raccordable passive à large bande. L'élément rayonnant de l'antenne est constitué de toroïdes (T) superposés reliés en série, des moyens (a, c) étant prévus pour court-circuiter les toroïdes individuellement et à la demande, et des moyens (b, d) étant prévus pour interrompre la liaison entre deux toroïdes successifs quelconques. L'invention s'applique notamment à la gamme de fonctionnement 30-512 MHz.
