Title
(EN) DIRECTIVE BEAMFORMING ANTENNA
(FR) ANTENNE DE FORMATION DE FAISCEAU DIRECTIONNEL
Abstract
(EN)
An antenna assembly includes a plurality of antenna elements disposed in a circular pattern and equidistant from each other in angular separation relative to a common reference point at a center of the circular pattern. The antenna assembly may include or be operably coupled to a phase control module configured to apply selected phase fronts to each of the antenna elements to generate constructive and destructive interference patterns to define a directive beam in a desired direction. The selected phase fronts may include no phase adjustment, a positive phase adjustment value and a negative phase adjustment value, the positive and negative phase adjustment values each having a same magnitude.
(FR)
L'invention concerne un ensemble antenne comprenant une pluralité d'éléments d'antenne disposés selon un motif circulaire et équidistants les uns des autres dans une séparation angulaire par rapport à un point de référence commun au centre du motif circulaire. L'ensemble antenne peut comprendre ou être couplé de manière fonctionnelle à un module de commande de phase configuré pour appliquer des fronts de phase sélectionnés à chacun des éléments d'antenne pour générer des motifs d'interférence constructive et destructive pour définir un faisceau directionnel dans une direction souhaitée. Les fronts de phase sélectionnés peuvent comprendre aucun reglage de phase, une valeur de reglage de phase positive et une valeur de reglage de phase négative, les valeurs de réglage de phase positive et négative ayant chacune une même amplitude.
