Abstract

L’invention concerne un procédé de formation de faisceau à lobes secondaires atténués ainsi qu’un schéma d’antenne double faisceau, susceptibles d’être utilisés de préférence dans un système de communication cellulaire à 3 secteurs et à 6 secteurs. L’antenne complète combine des sous-réseaux (modules) double faisceau à 2, 3 ou 4 colonnes à un réseau conformateur de faisceau (BFN) amélioré. Les modules peuvent être utilisés conjointement pour former un réseau, ou indépendamment pour former une antenne double faisceau. L’intégration de modules de types différents pour former un réseau complet permet d’obtenir une antenne double faisceau améliorée offrant une suppression améliorée des lobes secondaires en azimut dans une large bande de fréquences de fonctionnement, avec une meilleure couverture d’un secteur cellulaire souhaité et moins d’interférences avec d’autres cellules. L’invention permet avantageusement d’obtenir un meilleur rendement cellulaire avec jusqu’à 95% de la puissance rayonnée dirigée vers un secteur cellulaire souhaité.
