CA 2506198

The invention relates to a two-dimensional antenna array which is characterised by the following: at least two vertically extending gaps (5a, 5b) are present in said array; a radiator arrangement is respectively provided in each of the at least two vertically extending gaps (5a, 5b), said arrangements being separately fed; the radiator arrangement provided each gap (5a, 5b) respectively comprises at least one radiator or a radiator group (9); at least one additional radiator or an additional radiator group (109b or 109a) is provided for at least one gap (5a, 5b) in such a way that it is vertically staggered in relation to the radiator arrangement provided; and the at least one additional radiator or the at least one additional radiator group (109b or 109a) is fed by means of the radiator arrangement located in the other gap (5b or 5a).

L'invention concerne un réseau d'antennes bidimensionnel présentant les caractéristiques suivantes : au moins deux fentes (5a, 5b) s'étendant verticalement ; dans chacune des fentes (5a, 5b) s'étendant verticalement se trouvent respectivement un ensemble antenne rayonnante, les ensembles antennes rayonnantes étant alimentés séparément l'un de l'autre ; chaque ensemble antenne rayonnante monté dans chaque fente (5a, 5b) comprend au moins une antenne rayonnante ou un groupe d'antennes rayonnantes (9) ; dans au moins une fente (5a, 5b), au moins une antenne rayonnante supplémentaire ou un groupe d'antennes rayonnantes supplémentaires (109b ou 109a) est ajouté(e) à l'ensemble antenne rayonnante prévue avec un décalage dans le sens vertical ; et l'antenne rayonnante ou les antennes rayonnantes supplémentaires ou bien le groupe ou les groupes d'antennes rayonnantes supplémentaires (109b ou 109a) sont alimentés avec l'ensemble antenne rayonnante disposé dans l'autre fente (5b ou 5a).
