Title:
ANTENNA DEVICE AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2021145232
Kind Code:
A
Abstract:
To provide an antenna device that is not easily affected by nearby dielectrics and is easy to fit on a curved surface.SOLUTION: An antenna device includes an insulating and flexible sheet, an antenna element provided on one main surface of the flexible sheet, and a conductive layer provided on the other main surface of the flexible sheet. The antenna element is in the form of a film and has flexibility. The conductive layer is arranged on the side of the flexible sheet opposite to the antenna element. The conductive layer is also film-like and has flexibility. Therefore, the conductive layer can be curved integrally with the flexible sheet. That is, when the flexible sheet is curved, the antenna element and the conductive layer are curved following the flexible sheet while maintaining a distance between the antenna element and the conductive layer.SELECTED DRAWING: Figure 1
