Abstract
L'invention concerne les antennes à réseau de phase. Pour réduire l'erreur de quantification de phase d'une antenne à réseau de phase, on traduit des réglages de phase de valeur fixe 41, 43, 45, 47 dans le circuit d'attaque de l'un des éléments de chaque paire d'éléments symétriques 32, 32', etc. Il en résulte un décalage des fonctions de phase en escalier qui constituent une approximation des fonctions de phase idéales des éléments, en fonction de l'angle de balayage, et ce décalage réduit l'erreur de quantification de phase, et donc l'erreur de pointage du faisceau de l'antenne. Application aux systèmes d'atterrissage micro-ondes.
