Title (EN) INTEGRATED ADAPTIVE PHASED ARRAYS AND SECTOR ANTENNAS
(FR) ANTENNES SECTORIELLE ET ADAPTATIVE INTEGREES
Abstract:
(EN) The physical space available to install both a sector antenna and an adaptive, phased-array antenna at a cellular radio telecommunications base station may be significantly reduced, and the costs associated with manufacturing, installing and maintaining both a sector antenna and an adaptive, phased-array antenna may be appreciably reduced by incorporating the sector antenna and the phased-array antenna into a single antenna cartridge. In so doing, both the sector antenna and the adaptive, phased-array antenna may be supported by a single radio transceiver unit.
(FR) 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.
