CA 2331416

An improved antenna array comprises at least two vertically superposed primary radiator modules (1, 3) located in front of a reflector (5), and is characterised as follows: At least one first primary radiator module (1) of a first type and at least one second primary radiator module (3) of a second type are provided, these being vertically superposed at a distance; the primary radiator module(s) (1) of the first type has/have a different horizontal half-value width to the primary radiator module(s) (3) of the second type, so that it is possible to obtain a different horizontal total half-width value of the whole antenna; and the primary radiator module(s) (1) of the first type have a different constructional configuration to the primary radiator module(s) (3) of the second type.

Un réseau d'antennes perfectionné comporte au moins deux modules excitateurs (1, 3) superposés verticalement, lesquels se trouvent devant un réflecteur (5). Le perfectionnement consiste dans les caractéristiques suivantes: il est prévu au moins un premier module excitateur (1) d'un premier type et au moins un deuxième module excitateur (3) d'un deuxième type, qui sont superposés verticalement avec un espacement, le ou les modules excitateurs (1) du premier type présentent, par rapport au ou aux modules excitateurs (3) du deuxième type, une largeur de lobe horizontale différente, ce qui permet d'obtenir une largeur de lobe totale horizontale de l'antenne globale différente des deux largeurs de lobe, et le ou les modules excitateurs (1) du premier type présentent, par rapport au ou aux modules excitateurs (3) du deuxième type, une configuration différente.
