CA 2403430

The invention relates to a broad band communications antenna that is provided with a base plate (13) which is provided with a conductive layer (14) that is provided with at least one coupler opening. A strip line network (15) is provided at a little distance from the conductive layer (14) in the region of the coupler openings. At least one conductive patch (16, 17) is arranged opposite the base plate (13). The base plate (13) and the patch (16, 17) are arranged in a conductive housing (2) which is provided with an open side (19). The base plate is arranged closest to the bottom (3) of the housing and therefore farthest from the open side (19). One or more link/s (5) is/are provided on the open side (19) of the housing (2). Said link/s reduce/s the open cross-sectional surface of the housing (2) when the open side (19) is seen from above.

La présente invention concerne une antenne de communication à large bande comprenant une plaque de base (13) qui présente une couche conductrice (14) pourvue d'au moins une ouverture de connexion. Un réseau de lignes à ruban (15) est pourvu à faible distance de ladite couche conductrice (14), dans la zone des ouvertures de connexion. Au moins une pièce conductrice (16, 17) est montée face à la plaque de base (13). La plaque de base (13) et la pièce (16, 17) sont montées dans un boîtier conducteur (2), qui présente une face ouverte (19). La plaque de base est montée de manière le plus proche du fond du boîtier (3) et, par conséquent, la plus éloignée de la face ouverte (19). Une ou plusieurs languettes (5) est/sont pourvue(s) sur la face ouverte (19) du boîtier (2). Cette/ces languette(s) réduit/réduisent l'aire de la section ouverte du boîtier (2), lorsque la face ouverte (19) est vue de dessus.
