Abstract
An electromagnetic bandgap (EBG) structure for improving isolation characteristics between antennas of a MIMO antenna array. The structure includes an EBG unit cell formed on a metal layer over a composite dielectric substrate and over a ground plane. The ground plane may include a defected ground structure to further improve isolation, and another metal layer including a substrate integrated waveguide may be included at an interface of the composite dielectric substrate.
