Abstract

La présente invention se rapporte à un appareil d'antenne. L'appareil d'antenne comprend: au moins une couche diélectrique; une pluralité de premières électrodes transparentes placées sur une première surface de la couche diélectrique et ayant une transparence correspondant à une première valeur prédéterminée; une seconde électrode transparente placée sur une seconde surface de la couche diélectrique et ayant une transparence correspondant à une seconde valeur prédéterminée; et un élément d'isolement transparent ayant une transparence correspondant à une troisième valeur prédéterminée et éliminant un couplage mutuel entre au moins deux de la pluralité de premières électrodes transparentes. Par conséquent, la présente invention peut empêcher un couplage mutuel entre une pluralité d'antennes pour mettre en oeuvre un système à entrées multiples et sorties multiples (MIMO), et permet également de mettre en oeuvre de manière transparente toutes les électrodes et les éléments d'isolement empêchant un couplage mutuel des antennes, de telle sorte que la surface avant d'un panneau d'affichage d'un dispositif mobile peut également recevoir un appareil d'antenne.
