Title
(EN) MIMO ANTENNA ARRAY DECOUPLER
(FR) DÉCOUPLEUR DE RÉSEAU D'ANTENNES MIMO
Abstract
(EN) An antenna assembly includes a substrate, an antenna element disposed in connection with the substrate and a dielectric stub member disposed over the antenna element. The dielectric stub member has an effective dielectric constant that is in a range of 2.0 to and including 6.0. Mutual couplings in dual-polarized, wideband and large-scale MIMO antenna arrays in the 5G millimeter-wave band are reduced by weakening the space wave couplings. Mutual coupling reduction in a wide band is realized due to the non-resonant properties of the dielectric stub members. The effective dielectric constant of the dielectric stub members determines the decoupling performance.
(FR) Un ensemble antenne comprend un substrat, un élément d'antenne disposé en connexion avec le substrat et un élément de segment diélectrique disposé sur l'élément d'antenne. L'élément de segment diélectrique a une constante diélectrique efficace qui est dans une plage de 2,0 à 6,0 inclus. Des couplages mutuels dans des réseaux d'antennes MIMO à double polarisation, à large bande et à grande échelle dans la bande d'ondes millimétriques 5G sont réduits par affaiblissement des couplages d'ondes spatiales. La réduction de couplage mutuel dans une large bande est réalisée en raison des propriétés non résonantes des éléments de segment diélectrique. La constante diélectrique efficace des éléments de segment diélectrique détermine les performances de découplage.
