Abstract
L'invention concerne un système d'établissement de communications sans fil et d'utilisation de celui-ci, utilisant une antenne à lentille dotée d'une lentille à corps diélectrique. La lentille focalise des signaux de sortie HF en des signaux HF faisceau lumineux étroit, qui sont dirigés sur un dispositif récepteur spécifique. La lentille focalise des signaux d'entrée HF sur un équipement processeur de signaux. On peut avoir recours à ce système de communications fonctionnant entre deux dispositifs de communication ou davantage, qui utilise une lentille à corps diélectrique et un équipement processeur de signaux, pour établir des communications point à point ou point à multipoint.
