CA 2393570
The invention relates to a sensor of the type that comprises a system of co- localized antennae, itself comprising at least two active antennae (1) with the same phase center, said antennae being placed at the top end of a mast (4) and connected to down conductors (3). According to the invention, said mast (4) is produced from a dielectric material in such a way as to enable the antennae to be decoupled. The sensor also has filtering means (51 to 5n) which are arranged on at least one of said down conductors.
L'invention concerne un capteur du type comprenant un système d'antennes co-localisées, comprenant lui-même au moins deux antennes actives (1) ayant un même centre de phase, lesdites antennes étant placées à une extrémité haute d'un mât (4) et étant connectées à des câbles de descente (3). Selon l'invention, de façon à effectuer un découplage desdites antennes, ledit mât (4) est réalisé dans un matériau diélectrique. En outre, ledit capteur comprend des moyens de filtrage (5¿1? à 5¿n?) disposés sur au moins un desdits câbles de descente.
