Abstract: The invention relates to an antenna designed to emit and/or receive surface waves with a decametric, hectometric or kilometric central wavelength λ0, characterised in that it comprises at least one horizontal wire aerial element of between 0.5λ0 and λ0 in length, and at least three vertical wire aerial elements of the same length between 0.03λ0 and 0.1λ0, arranged in a same plane and each comprising an upper end and a lower end, said upper ends being connected to the horizontal wire aerial element, said lower ends being designed to be connected to a conducting medium having a substantially horizontal surface. The invention also relates to an antenna, an antenna array and a use of an antenna or of an antenna array.

Abstract: The invention relates to a surface wave antenna system, comprising at least one antenna that is electrically short in the vertical plane, with vertical or elliptic polarization and emitting a radiation, said antenna being linked to a conducting medium exhibiting a substantially horizontal surface. The antenna system being characterized in that it comprises furthermore at least one parasitic wire extending in a direction substantially parallel to the surface of the conducting medium, electrically insulated from each antenna, and arranged in the vicinity of at least one antenna in such a way as to be able to radiate by virtue of the current induced by said radiation of this antenna. The invention makes it possible to combine the resultants of each radiating element in such a way as to control the radiation pattern in the vertical plane.
