Abstract

L'antenne réseau à commande de phase concerne le domaine des équipements radio et notamment des moyens de communication, et plus particulièrement des antennes en spirale millimétriques et décimétriques pour dispositif d'émission / réception. L'antenne est constituée d'un vibreur actif demi-onde, de deux spirales connectées entre elles et disposées en série, et d'une ligne d'alimentation sous la forme d'un câble coaxial avec un gainage formant écran. Les spirales sont planes, sont disposées en ligne et se présente comme une chaîne constituée de boucles. Une des spirales se présente comme une continuation dudit câble coaxial à travers les boucles duquel on a enfilé, vers l'avant ou en sens inverse, le conducteur d'une autre spirale. Dans le plan du vibreur actif on a disposé un vibreur passif qui se présente comme une spirale à boucles d'une partie en boucle identique de la spirale en fil du vibreur actif. La distance entre les vibreurs est déterminée par la formule L1=(λ/32)...(λ/8), la longueur électrique des deux vibreurs est comprise dans les dimensions L2 = (λ/8)...(λ/2), et la spirale du vibreur passif possède un nombre pair de zones de pli, son pas et le pas de la partie en fil de la spirale du vibreur actif étant compris dans les limites L3 =(λ/128)...(λ/32), lesdits vibreurs et câble d'alimentation d'antenne étant disposés dans un boîtier imperméable aux ondes radio. Ce boîtier se présente comme un ensemble de modules séparés imperméables aux ondes radio et reliés entre eux avec un raccord destiné à accueillir le câble d'alimentation.
