Patent

CA 2228548

The invention concerns an antenna array for simultaneously receiving or simultaneously emitting electromagnetic waves with two linear orthogonal polarizations, the antenna array comprising a decoupling arrangement (17) between adjacent radiator modules (1). The decoupling arrangement is provided between two radiator modules (1) which are adjacent in the mounting direction (21). The object of the invention is to improve the antenna array by providing between two adjacent radiator modules (1) a decoupling structural element (17) of which at least the longitudinal component extends in the mounting direction (21), the length of this longitudinal component being greater than or equal to 25 % of the distance (25) between the centres or bases (23) of the corresponding adjacent radiator modules (1).

L'invention concerne un réseau d'antennes pour la réception simultanée ou diffusion simultanée d'ondes électromagnétiques avec deux polarisations orthogonales linéaires qui présente un dispositif de désaccouplage (17) entre deux modules radiants (1). Ce dispositif de désaccouplage est prévu entre deux modules radiants (1) adjacents dans le sens de montage (21). L'amélioration réside dans le fait qu'il prévu entre deux modules radiants (1) adjacents, un élément structural de désaccouplage (17) qui s'étend au moins dans le sens de montage (21) avec sa partie longitudinale, ladite partie longitudinale ayant une longueur supérieure ou égale à 25 % de la distance (25) entre les centres ou bases (23) des modules radiants (1) adjacents correspondants.
