In accordance with the present invention, there is provided a patch antenna assembly (10) having a generally planar patch antenna (12), defined by a first peripheral boundary (14), and a generally planar parasitic ground plate (16), disposed at a spaced parallel relation to the patch antenna (12). The assembly (10) further includes at least one conductive parasitic shielding element (18) for segregating electromagnetic fields between the patch antenna (12) and the ground plate (16). The shielding element (18) is disposed in electrical communication with the ground plate (16) and extends from the ground plate (16) and substantially about the first peripheral boundary (14) of the patch antenna (12).
L'invention concerne un ensemble à antenne à plaque (10) constitué d'une antenne à plaque généralement plane (12), définie par une première limite périphérique (14), et d'une plaque de terre généralement plane (16), placée parallèlement à l'antenne à plaque (12). L'ensemble (10) comporte également au moins un élément de blindage conducteur non alimenté (18) qui sépare les champs électromagnétiques entre l'antenne à plaque (12) et la plaque de terre (16). L'élément de blindage (18) est en communication électrique avec la plaque de terre (16) et s'étend sensiblement de la plaque de terre (16) et sensiblement autour de la première limite périphérique (14) de l'antenne à plaque (12).
