CA 2496757

A directive antenna having plural antenna elements is arranged in a parasitic antenna array. Frequency selective components are connected to a first subset of the antenna elements. Weighting structures are connected to a second subset of the antenna elements. The first and second subsets of antenna elements may be connected by a space-fed power distribution system to produce independently steerable beams having spectrally separated signals.

L'invention concerne une antenne de directivité comprenant plusieurs éléments d'antenne, placée dans un réseau d'antenne parasite. Des composants sélectifs sont connectés à un premier sous-ensemble des éléments d'antenne. Des structures de pondération sont connectées à un second sous-ensemble des éléments d'antenne. Le premier et le second sous-ensemble des éléments d'antenne peuvent être connectés par un système de distribution d'énergie alimenté dans l'espace, afin de générer des faisceaux orientables indépendants dont les signaux sont séparés d'un point de vue spectral.
