Abstract
(EN)
A MIMO communication system is provided. The system may include a first antenna comprising a first cavity, a first plurality of RF ports for generating a feed wave within the first cavity, and a first plurality of sub-wavelength artificially structured material elements as arranged on a surface of the first cavity as RF radiators. The first antenna is configured to generate a plurality of radiation patterns respectively corresponding to the first plurality of ports. The system may also include a second antenna comprising a second cavity and a second plurality of sub-wavelength artificially structured material elements arranged on a surface of the second cavity.

L'invention concerne un système de communication MIMO. Le système peut comprendre une première antenne comprenant une première cavité, une première pluralité de ports RF pour générer une onde d'alimentation à l'intérieur de la première cavité, et une première pluralité d'éléments de matériau à structure artificielle de sous-longueur d'onde disposés sur une surface de la première cavité en tant qu'éléments rayonnants RF. La première antenne est configurée pour générer une pluralité de motifs de rayonnement correspondant respectivement à la première pluralité de ports. Le système peut également comprendre une seconde antenne comprenant une seconde cavité et une seconde pluralité d'éléments de matériau à structure artificielle de sous-longueur d'onde disposés sur une surface de la seconde cavité.
