Title (EN) ANTENNA ARRAY ASSEMBLY
(FR) ENSEMBLE RÉSEAU D'ANTENNES
Abstract:
(EN) An antenna array assembly comprises at least a first and second antenna element, each comprising at least one radiator element (3a, 3b) in a substantially parallel relationship to a respective ground plate (2a, 2b), and an isolator bar (1b) disposed between the respective ground plates (2a, 2b) of the first and second antenna elements, the isolator bar (1b) being elongate having a cross- section comprising a T shape, the cross-section being across a long axis. The isolator bar (1b) comprises a support bar in contact with the ground plates forming the stem of the T shape, and a cross piece forming the top of the T shape. The cross piece of the isolator bar has a width in the cross-section of at least a quarter of a wavelength at an operating frequency of the antenna array, whereby to provide radio frequency isolation between the first and second antenna elements.
(FR) Un ensemble réseau d'antennes comprend au moins un premier et un second élément d'antenne, chacun comprenant au moins un élément de radiateur (3a, 3b) dans une relation sensiblement parallèle à une plaque de terre (2a, 2b) respective, et une barre d'isolation (1b) disposée entre les plaques de terre (2a, 2b) respectives des premier et second éléments d'antenne, la barre d'isolation (1b) étant allongée et ayant une section transversale comprenant une forme en T, la section transversale étant sur un grand axe. La barre isolante (1b) comprend une barre de support en contact avec les plaques de terre formant la tige de la forme en T, et une pièce transversale formant la partie supérieure de la forme en T. La pièce transversale de la barre isolante a une largeur dans la section transversale d'au moins un quart d'une longueur d'onde à une fréquence de fonctionnement du réseau d'antennes, ce qui permet d'obtenir une isolation radiofréquence entre les premier et second éléments d'antenne.
