Abstract

Il est possible de réduire, de manière significative, l'espace physique disponible pour installer des antennes sectorielle et réseau à commande de phase adaptative au niveau d'une station de base de télécommunications radio cellulaire, ainsi que les coûts associés à leur fabrication, leur installation, et à leur maintenance par incorporation desdites antennes sectorielle et réseau à commande de phase dans une seule cartouche d'antenne. De ce fait, les deux antennes peuvent être supportées par une seule unité d'émetteur-récepteur radio.
