Abstract
An antenna device comprises a cell structure including a plurality of cells made up of a multi-layer structure including a conductor layer and a dielectric layer, arranged in a matrix, and further comprises a first antenna element and a second antenna element arranged over the cell structure. The cells are configured to have artificial magnetic conductor effects corresponding to different frequency bands in a first direction and a second direction, and the first antenna element and the second antenna element are arranged parallel to the surface of the cell structure, respectively along the first direction and the second direction.
