Abstract

Un système antennaire à au moins une fente est décrit. Il comprend au moins un câble coaxial (204) comprenant une partie intermédiaire (206) à nu, la partie intermédiaire à nu étant positionnée en regard de ladite fente de telle sorte à effectuer un couplage électromagnétique du câble coaxial avec la fente. La partie intermédiaire (206) à nu est séparée d’une extrémité du câble coaxial (204) par un tronçon de câble non-nu en circuit ouvert formant un dispositif d’adaptation d’impédance du système antennaire.
