摘要: The invention concerns an antenna intended to transmit and/or receive surface waves having a decametric, hectometric, or kilometric central wavelength λ
0 , characterised in that it comprises at least one horizontal wire radiating element (22) having a length of between 0.5 λ
0 and λ
0 , and at least three vertical wire radiating elements (24a-24c) of the same length of between 0.03 λ
0 and 0.1 λ
0 , disposed in a same plane and each comprising an upper end and a lower end, said upper ends being linked to the horizontal wire radiating element (22), said lower ends being suitable for being linked to a conductive medium (26) having a substantially horizontal surface. The invention also concerns an antenna array and a use of an antenna or an antenna array.-

摘要: The invention relates to a surface wave antenna system, comprising at least one antenna (22) electrically shorted in the vertical plane, having vertical or elliptical polarisation and being suitable for emitting/receiving radiation in at least one frequency band centred on a central frequency f
0 associated with a central wavelength λ
0 , said antenna (22) being connected to a conducting medium (28) having a substantially horizontal surface, the antenna system being characterised in that it further comprises at least one wired cover (30) of length greater than or equal to 0.8 λ
0 , electrically connected to at least one antenna (22) at the centre of the cover (30), and suitable for radiating at least at the central frequency f
0 of the antenna (22).-

摘要: The invention relates to a surface wave antenna system (22), comprising at least one antenna (24) that is electrically short in the vertical plane, with vertical or elliptic polarization and emitting a radiation, said antenna (24) being linked to a conducting medium (28) exhibiting a substantially horizontal surface. The antenna system (22) being characterized in that it comprises furthermore at least one parasitic wire (30) extending in a direction substantially parallel to the surface of the conducting medium (28), electrically insulated from each antenna (24), and arranged in the vicinity of at least one antenna (24) in such a way as to be able to radiate by virtue of the current induced by said radiation of this antenna (24). 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.
