Title
(EN) MULTIBAND ANTENNA ARRAY USING ELECTROMAGNETIC BANDGAP STRUCTURES
(FR) RÉSEAU D'ANTENNES MULTIBANDES UTILISANT DES STRUCTURES ÉLECTROMAGNÉTIQUES À LARGEUR DE BANDE INTERDITE
Abstract
(EN)
In some embodiments, a multiband antenna array using electromagnetic bandgap structures is presented. In this regard, an antenna array is introduced having two or more planar antennas situated substantially on a surface of a substrate, a first set of electromagnetic bandgap (EBG) cells situated substantially between and on plane with the antennas, and a second set of EBG cells situated within the substrate below the antennas. Other embodiments are also disclosed and claimed.
(FR)
Dans certains modes de réalisation, l'invention concerne un réseau d'antennes multibandes utilisant des structures électromagnétiques à largeur de bande interdite. A cet égard, on utilise un réseau d'antennes ayant deux ou plus de deux antennes planes situées sensiblement sur une surface d'un substrat, une première série de cellules électromagnétiques à largeur de bande interdite (EBG) situées sensiblement entre les antennes, et sur le même plan que celles-ci, et une seconde série de cellules EBG situées dans le substrat en dessous des antennes. L'invention concerne aussi d'autres modes de réalisation.
