Abstract

An antenna system including antenna elements and a tracking method is considered a key technology in mobile communication systems. A phased array antenna has been considered the most favorite candidate because of many attractive characteristics such as a low and compact profile, high-speed tracking and potentially low cost performance for vehicle antennas in mobile communications. On the other hand, it has several such disadvantages as beam steering error, loss in feed lines and an increase of noise level in a receiving frequency band. Some of phased array antennas have already been used in satellite communications, and some of them are under development. This paper overviewed basic performance and some examples of phased array antennas for especially satellite mobile communications.

Résumé

Un système d’antenne incluant des éléments rayonnants et un modèle de poursuite est considéré comme un point clef dans la technologie des systèmes de communication avec des mobiles. Le réseau a commande de phase a été longtemps considéré comme le meilleur candidat du fait de ses nombreuses propriétés attractives telle que sa compacité, sa vitesse de poursuite, etsonfaible coûtpoten-tiel. D’un autre côté, ilprésente des inconvénients, comme I’erreur de pointage, les pertes dans les lignes d’alimentation et l’élévation du niveau de bruit dans les bandes de réception. Des réseaux à commande de phase ont déjà été utilisés en communication par satellite, et d’autres sont en cours de développement. Cet article présente les performances de bases ainsi que quelques exemples de réseaux destinés au service mobile par satellite.
