Abstract

Le domaine de l’invention est celui des procédés d’intégration d’une antenne réseaux (A) dans un milieu (M), ladite antenne comportant une pluralité d’éléments rayonnants (ERT) assurant la transition entre l’antenne et le milieu, la réflectivité de chaque élément dépendant d’un paramètre, la réflectivité d’un premier élément étant voisine du celle du milieu, la réflectivité d’un dernier élément étant voisine de celle de l’antenne, le paramètre de réflectivité des éléments variant d’un élément au suivant. Le procédé selon l’invention comporte les étapes suivantes :- Etape 1 : Calcul d’un chemin égal à la somme des variations de la réflectivité d’un élément à l’élément suivant ;- Etape 2 : Optimisation de la variation du paramètre de réflectivité de façon que la surface équivalente radar de l’antenne soit la plus faible possible ou que l’antenne respecte au mieux les objectifs de rayonnement ;- Etape 3 : Détermination des différents éléments en fonction dudit paramètre ;- Etape 4 : Simulation de la réflectivité globale et/ou du rayonnement de l’antenne.
