Claims (9)

  1. Antenne plane (30) comprenant un élément conducteur rectangulaire formé de deux éléments conducteurs carrés (12, 13), ces éléments conducteurs carrés étant définis à l'intérieur du rectangle par un conducteur de retour placé au centre (14), chaque élément conducteur carré (12, 13) étant connecté, par une extrémité, à un élément de connecteur (20) et, par l'autre extrémité, au conducteur de retour (14), les dimensions des éléments conducteurs carrés (12, 13) étant choisies de manière à maximiser le gain pour des fréquences radio sélectionnées,
    caractérisée en ce que
    cette antenne (30) comprend en outre un ou plusieurs éléments conducteurs carrés supplémentaires (18, 17) disposés à l'intérieur des éléments carrés, chaque élément conducteur carré supplémentaire (18, 17) étant connecté à l'élément conducteur carré respectif (12, 13) par une extrémité, et se trouvant défini par le conducteur de retour (14) sur un côté.
  2. Antenne (30) selon la revendication 1,
    dans laquelle
    les éléments conducteurs carrés (12, 13, 14, 17, 18) sont formés sur un substrat (11).
  3. Antenne (30) selon la revendication 2,
    dans laquelle
    le substrat (11) est un film flexible.
  4. Antenne (30) selon la revendication 2 ou la revendication 3,
    dans laquelle
    le substrat (11) est transparent.
  5. Antenne (30) selon la revendication 1,
    dans laquelle
    tous les éléments conducteurs carrés (12, 13, 17, 18) sont connectés électriquement au même élément de connecteur (16), tandis que le conducteur de retour (14) est connecté à un élément de connecteur électriquement séparé (15).
  6. Antenne (30) selon la revendication 2,
    dans laquelle
    les éléments conducteurs carrés (12, 13, 14, 17, 18) ont été créés par un procédé comprenant les étapes consistant à :
    imprimer un motif conducteur sur le substrat (11) en utilisant de l'encre conductrice ; et
    déposer électrolytiquement un autre matériau conducteur sur le motif conducteur imprimé, en utilisant le motif formé par l'encre conductrice comme électrode dans un processus d'électroplacage.
  7. Antenne (30) selon la revendication 6,
    dans laquelle
    le motif conducteur est imprimé à l'écran sur le substrat (11).
  8. Antenne (30) selon la revendication 7,
    dans laquelle
    une pluralité de motifs conducteurs est imprimée sur le substrat (11) et, après électrodéposition, un film protecteur est appliqué au motif conducteur.
  9. Antenne (30) selon la revendication 8,
    dans laquelle
    le film protecteur est adhésif des deux côtés.
