Abstract
(EN)
In an example implementation, an antenna assembly includes an antenna array, a dielectric cover, and a superstrate metal patch with coupling lines. The superstrate metal patch with coupling lines is placed under the dielectric cover and about λ/2 above the antenna array. λ is wavelength of operating frequency of the antenna array. The coupling lines are connected to the superstrate metal patch, and the coupling lines are extended from the superstrate metal patch.

L'invention, selon un mode de réalisation donné à titre d'exemple, concerne un ensemble antenne comprenant un réseau d'antennes, un couvercle diélectrique et une pièce métallique de superstrat doté de lignes de couplage. La pièce métallique de superstrat dotée de lignes de couplage est placée sous le couvercle diélectrique et à environ λ/2 au-dessus du réseau d'antennes. λ est une longueur d'onde de la fréquence de fonctionnement du réseau d'antennes. Les lignes de couplage sont connectées à la pièce métallique de superstrat, et les lignes de couplage s'étendent à partir de la pièce métallique de superstrat.
