(FR) DÉPHASEUR D'ANTENNE DE STATION DE BASE INTÉGRÉ ET COMPENSÉ EN PHASE ET TABLEAU D'ÉTALONNAGE
Abstract
(EN) Disclosed is an antenna having a plurality of radiator columns and an integrated phase shifter / calibration board. The radiator columns have radiator clusters that may be differentially phase to provide beam tilt. The input traces of each of the phase shifters is capacitively coupled to a Wilkinson power divider that sums the power of all the input signals, thereby providing a calibration function. The output traces of each of the phase shifters has a designated meander pattern that provides phase alignment for all the output signals to prevent phase mismatches between signals fed to the radiator clusters.
(FR) L'invention concerne une antenne ayant une pluralité de colonnes de radiateurs et un déphaseur/tableau d'étalonnage intégré. Les colonnes de radiateurs ont des groupes de radiateurs qui peuvent être phasés de manière différentielle pour assurer l'inclinaison de faisceau. Les traces d'entrée de chacun des déphaseurs sont couplées capacitivement à un diviseur de puissance de Wilkinson qui additionne la puissance de tous les signaux d'entrée, assurant ainsi une fonction d'étalonnage. Les traces de sortie de chacun des déphaseurs ont un motif en méandres désigné qui assure l'alignement de phases pour tous les signaux de sortie pour empêcher les défauts d'appariement de phase entre des signaux transmis aux groupes de radiateurs.
