Title
(EN) IMPROVED LENS SYSTEM FOR ANTENNA SYSTEM
(FR) SYSTEME DE LENTILLES D'ANTENNE AMELIORE
Abstract
(EN)
An antenna system (30) includes a lens (40, 50) and a plurality of non-uniform feed elements (42, 52). The non-uniform feed elements (42, 52) are coupled to the lens system and operable to shape each of a plurality of beams (32) to match an angular size of a ground-based cell (20) assigned to the beam (32).
(FR)
Système d'antenne (30) comprenant une lentille (40, 50) et une pluralité d'éléments non uniformes (42, 52) de mise en forme de faisceau. Ces éléments (42, 52) sont couplés au système de lentilles et servent chacun à mettre en forme une pluralité de faisceaux (32), de manière à correspondre à une dimension angulaire d'une cellule (20) basée au sol et affectée au faisceau (32).
