An array antenna in which a base (31) on which a plurality of antenna elements (34) are arranged as well as a radome (35) for covering the plurality of antenna elements (34) are formed as curved so as to coincide with the curved surface configuration of a wall body (47) or the like on which the antenna is to be mounted. A power supply system which comprises an opening (135) provided in a wall body (134) on which an array antenna is to be mounted, a cylindrical member (136) provided at a peripheral edge part of the opening (135), a group of power supply connectors (124) disposed at a location of the array antenna corresponding to the opening (135) of the wall body (134), a group of power supply lines (143) disposed in an interior of the cylindrical member (136) to be connected to the group of power supply connectors (124), and adhesive (146) sealingly filled in the interior of the cylindrical member (146) between the power supply lines (143) to seal the cylindrical member.

L'invention est une antenne réseau dans laquelle une base (31) sur laquelle une pluralité d'éléments d'antenne (34) sont installés avec un radôme (35) servant à les recouvrir. Ces éléments sont courbés pour s'adapter à la surface courbe d'une paroi (47) ou d'une entité similaire sur laquelle l'antenne doit être montée. L'installation comprend les éléments suivants : un système d'alimentation utilisant une ouverture (135) pratiquée dans la paroi (134) sur laquelle l'antenne réseau doit être montée, un élément cylindrique (136) monté à la périphérie de l'ouverture (135), un groupe de connecteurs d'alimentation (124) montés sur l'antenne réseau à l'endroit correspondant à l'ouverture (135) pratiquée dans la paroi (134), un groupe de lignes d'alimentation (143) disposées à l'intérieur de l'élément cylindrique (136) qui doivent être connectées au groupe de connecteurs d'alimentation (124), et un agent adhésif (146) remplissant dans l'élément cylindrique (146) l'espace entre les lignes d'alimentation (143) pour rendre cet élément cylindrique hermétique.
