Abstract

Un satellite de télécommunications à couverture multi-zones comporte au moins une antenne d'émission et/ou de réception comprenant au moins une source d'émission et/ou de réception (C, R) pour délivrer et/ou recevoir un faisceau selon une direction choisie définie par une phase de valeur choisie et une amplitude de valeur choisie. L'une au moins des sources d'émission et/ou de réception (C, R) est couplée à des moyens de traitement (MT) chargés de dévier son faisceau ou sa direction de réception selon au moins une autre direction choisie par variation d'au moins la valeur de l'amplitude.
