Abstract

L'invention concerne une antenne à base des cellules métamatériaux pour les applications 6G dans la bande sous-térahertz; l'antenne comprend un substrat diélectrique qui est pourvu d'une première surface latérale et d'une seconde surface latérale qui sont opposées l'une à l'autre; la ligne microruban, le patch et les cellules métamatériaux sont disposée sur la première surface latérale; le plan de masse est disposée sur la deuxième surface latérale; le guide d'ondes intégré au substrat est synthétisé en mettant deux rangées de vias métalliques dans le substrat. Les cellules métamatériaux ont été ajoutés à l'antenne qui a été imprimée sur un guide d'ondes intégré au substrat pour améliorer ses performances en ce qui concerne les paramètres critiques tels que le gain et la bande passante ainsi que le rapport axial; ces cellules métamatériaux ont été placées entre deux ports d'onde, l'une le long de l'axe z négatif et l'autre le long de l'axe z positif; lesdites cellules ont été élaborés avec des indices de réfraction proche de Zéro et une perméabilité négatif. L'antenne conçue présente des avantages intéressants tels que : une large bande de couverture et une polarisation circulaire. Ces excellentes performances rendent cette antenne très prometteuse pour les applications 6G dans la bande sous-térahertz.The invention relates to a metamaterial cell-based antenna for 6G applications in the sub-terahertz band; the antenna comprises a dielectric substrate which is provided with a first side surface and a second side surface which are opposite to each other; the microstrip line, the patch and the metamaterial cells are arranged on the first side surface; the ground plane is arranged on the second side surface; the substrate-integrated waveguide is synthesized by putting two rows of metal vias in the substrate. The metamaterial cells were added to the antenna which was printed on a substrate-integrated waveguide to improve its performance with respect to critical parameters such as gain and bandwidth as well as axial ratio; these metamaterial cells were placed between two waveports, one along the negative z-axis and the other along the positive z-axis; The said cells have been developed with refractive indices close to zero and negative permeability. The designed antenna has interesting advantages such as: a wide coverage band and circular polarization. These excellent performances make this antenna very promising for 6G applications in the sub-terahertz band.
