Patent

CA 2634640

This invention relates to reducing the complexity and cost of antenna arrays and is more specifically concerned with reducing the complexity of an antenna apparatus. It provides an antenna array (62) made up of a vertical stack of horizontal linear structures (74) each having several groups of neighbouring array antenna elements, the groups (74) having variable numbers of the antenna elements each connected to a transmit/receive module (66) . The advantage of this configuration is that less communication modules (66) , such as transmit/receive modules, are required to operate the antenna array (62) , reducing the weight, power consumption and cost of an antenna apparatus incorporating such an antenna array (62) without significantly limiting the capability and/or performance of a system compared to a conventional solution.

Cette invention porte sur la réduction de la complexité et du coût de réseaux d'antennes et elle est plus particulièrement concernée par la réduction de la complexité d'un appareil à antennes. Elle concerne un réseau d'antennes (62) constitué d'un empilement vertical de structures linéaires horizontales (74), chacune comportant plusieurs groupes d'éléments d'antennes en réseaux voisins, les groupes (74) comportant un nombre variable d'éléments d'antennes, chacune reliée à un module d'émission/réception (66). L'avantage de cette configuration est qu'il est requis moins de modules de communication (66), tels que les modules d'émission/réception, pour mettre en oeuvre le réseau d'antennes (62), ce qui réduit le poids, la consommation d'énergie et le coût d'un appareil à antennes incorporant un tel réseau d'antennes (62) sans limiter significativement la capacité et/ou les performances d'un système par comparaison à une solution classique.
