A miniaturized directional antenna for use with system to provide data communication over wireless radio channels. The unit supports multiple antenna elements with a known orientation with respect to an earth ground plane reference. This greatly provides predictability in the steerability and other directional attributes of the antenna array using miniaturized chip multilayer or helical antenna elements, the unit may be constructed in a case or other form factor of approximately 3 x 3 x 1 inches for operation within the frequency bands around 1900 MHz.

Cette antenne directionnelle miniaturisée est à utiliser avec un système assurant une communication de données sur des canaux radio sans fil. L'unité est pourvue de plusieurs éléments d'antenne ayant une orientation connue relativement à un plan de sol de référence. Cette disposition permet de prévoir les possibilités d'orientation du réseau d'antennes ainsi que d'autres attributs directionnels, et ce, au moyen d'une microplaquette multicouche ou d'éléments d'antenne en hélice. On peut donner à cette unité la forme d'un boîtier, ou une autre forme, dont les dimensions sont de 3 x 3 x 1 pouce, approximativement, pour une exploitation avec des bandes de fréquence d'environ 1900 MHz.
