Abstract: 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.

Abstract: 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.

Abstract: An illumination display panel that forms part of a housing and has a display portion for illuminated display comprises a resin panel having a first molded portion made of an opaque resin at a portion excluding the display portion, and a second molded portion disposed on the back surface side of the first molded portion and made of a light-transmitting resin having a protrusion where the first molded portion is not present. The protrusion is fitted to the first molded portion. A light source mounting substrate is disposed on the back surface side of the resin panel. At least a light source of the light source mounting substrate is sealed by the second molded portion. An integrally molded product of the light source mounting substrate and the second molded portion is filled and solidified at a low pressure while compressing a cavity of a molding mold.
