The invention relates to an antenna that produces a radiation pattern that is axisymmetric about a geometrical axis (X) and exhibits a radiation maximum in a plane perpendicular to the direction of said X axis that includes a feed wire (100) extending along said axis (X) from a first end (5a) situated level with a conducting surface forming an earth plane (300) of the antenna to a second end (5b) that feeds a set (200) of N radiating strands, N being an integer, characterized in that it also includes at least one earth return rod for the strands, said rod linking one of the radiating strands of the set (200) to the earth plane (300).
L'invention concerne une antenne produisant un diagramme de rayonnement de révolution autour d'un axe géométrique (X) et présentant un maximum de rayonnement dans un plan perpendiculaire à la direction dudit axe X incluant un fil d'alimentation (100) s'étendant le long dudit axe (X) d'une première extrémité (5a) situé au niveau d'une surface conductrice formant plan de masse (300) de l'antenne vers une seconde extrémité (5b) alimentant un ensemble (200) de N brins rayonnants, N étant un entier caractérisée en ce que elle inclut également au moins une tige de retour à la masse des brins, ladite tige reliant un des brins rayonnants de l'ensemble (200) au plan de masse (300).
