Title
(EN) METHOD FOR INTEGRATING A "NETWORK" ANTENNA INTO A DIFFERENT ELECTROMAGNETIC MEDIUM, AND ASSOCIATED ANTENNA
(FR) PROCEDE D'INTEGRATION D'UNE ANTENNE " RESEAUX " DANS UN MILIEU DE NATURE ELECTROMAGNETIQUE DIFFERENTE ET ANTENNE ASSOCIEE
Abstract
(EN)
The invention relates to a method for integrating a network antenna (A) into a medium (M), the antenna comprising a plurality of radiating elements (ERT) that ensure the transition between the antenna and the medium, the reflectivity of each element depending on a parameter, the reflectivity of a first element being close to that of the medium, the reflectivity of a last element being close to that of the antenna, and the reflectivity parameter of the elements varying from one element to the next. The method according to the invention comprises the following steps: - Step 1: computing a path equal to the sum of the variations in reflectivity from one element to the next element; - Step 2: optimising the variation in the reflectivity parameter such that the radar cross-section of the antenna is as low as possible or such that the antenna best fulfils the radiation objectives; - Step 3: determining the different elements according to the parameter; - Step 4: simulating the overall reflectivity and/or radiation of the antenna.

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.
