Abstract

L'invention concerne une antenne à fentes reconfigurable basée sur une structure en forme de croissant, qui comprend un substrat et une plaque métallique fixée à la surface supérieure du substrat. Deux fentes en forme de croissant à symétrie horizontale sont gravées sur la plaque métallique. Chaque fente en forme de croissant comprend une diode. La mise en oeuvre de l'invention permet, sans modifier le mode de polarisation, de changer la fréquence et le diagramme directionnel de rayonnement d'une antenne en temps opportun selon les exigences de communication, de façon à réduire le bruit spatial d'un système de communication sans fil, à éviter le brouillage électronique, à améliorer la sécurité du système, et à augmenter la capacité d'un canal.
