Abstract
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 extending along said axis (X) from a first end situated level with a conducting surface forming an earth plane of the antenna to a second end that feeds a set 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 to the earth plane.
