Abstract

La présente invention concerne un procédé et un appareil destinés à établir une multi-antenne dans un système entrée multiple sortie multiple à bande basse fréquence. Le procédé d'un mode de réalisation de la présente invention consiste à : choisir la taille des antennes en fonction des scénarios d'application ; choisir le support en fonction de la taille des antennes ; encapsuler les antennes dans le support. Le procédé et l'appareil du mode de réalisation de la présente invention permettent d'éviter le problème selon lequel l'espacement des antennes requis par l'application de la technique entrée multiple sortie multiple est supérieur à la taille de l'émetteur-récepteur lui-même sur les scénarios d'application à bande basse fréquence classique, la technique entrée multiple sortie multiple pouvant ainsi être mieux appliquée aux bandes basse fréquence.
