Abstract

Des structures d'antenne et des radômes chiraux (210, 260, 270, 290) peuvent constituer des radômes et des structures d'antenne efficaces et multipolaires (210, 260, 270, 290). Selon un mode de réalisation préféré, un radôme (210, 260, 270, 290) servant à recouvrir une antenne (230) comprend un milieu chiral. Selon un autre mode de réalisation préféré, un procédé de fabrication d'une structure d'antenne consiste à encastrer l'élément d'antenne (230) dans un radôme (210, 260, 270, 290) qui comprend en outre un milieu chiral.
