Abstract

L’invention concerne un système d’antenne comprenant : un plan de masse avec une cavité recouverte d’un substrat diélectrique, magnétique ou magnéto-diélectrique ; une antenne disposée sur la cavité ; une couronne périphérique absorbante disposée entre l’antenne et les parois de la cavité ; une demi-lentille absorbante, comprenant un élément de base couvrant sensiblement la moitié de la cavité Figure pour l’abrégé : Fig. 10.An antenna system includes: a ground plane with a cavity covered with a dielectric, magnetic or magneto-dielectric substrate; an antenna disposed on the cavity; an absorbent peripheral ring placed between the antenna and the walls of the cavity; an absorbent half-lens, comprising a base element covering substantially half of the cavity Figure for abstract: Fig. 10.
