An antenna device suppresses reflection of electromagnetic waves from a human body or other conductors, which causes the electromagnetic waves to be sufficiently emitted in a target direction. The antenna device includes an antenna pattern and a metasurface layer. The metasurface layer is a layer that is layered on the antenna pattern and disposed on the human body side. The metasurface layer includes a first low-loss film and a second low-loss film. A first metasurface is formed on the first low-loss film. A second metasurface is formed on the second low-loss firm.

Antenna device

A decrease in performance of an antenna is suppressed while maintaining metallic design by a metal vapor deposition layer in a cover with antenna function. A back cover includes cover member, a pictorial pattern layer, and a metasurface. The pictorial pattern layer is arranged in a layering direction with respect to the cover member and includes a metal vapor deposition layer. The metasurface is arranged side by side in the layering direction with the pictorial pattern layer. The metasurface amplifies an antenna signal.
