Abstract

La présente invention concerne un système à base radio, en particulier un système RFID ou un système de localisation radio. De manière efficace, les effets de diffusion à plusieurs voies doivent être réduits. Pour ce faire, une antenne (8) de station de base est constituée d'un certain nombre d'émetteurs (7). Ces émetteurs (7) sont commandés électroniquement pour le réglage d'une orientation d'action préférée de l'antenne au moyen d'un réseau d'alimentation (11) en termes de phase et/ou d'amplitude. Les émetteurs (7) envoient ou reçoivent des ondes électromagnétiques avec des états différents de phase et d'amplitudes. Ainsi, il se produit un réglage électrique de la direction préférée d'émission ou de réception. Cette invention est utilisée en particulier pour des systèmes RFID et des systèmes de localisation radio qui reposent sur une connexion visuelle directe entre une station de base (1) et des objets cibles (4). Des identifications et des localisations doivent être exécutables avec une fiabilité élevée.
