Communication sheet, smart shelf
First Claim
1. A communication sheet that transmits an electromagnetic wave for communication, comprising:
- a dielectric layer including a dielectric substrate;
a first conductor layer including a mesh sheet-like mesh conductor disposed on one surface of the dielectric substrate; and
a second conductor layer including a sheet-like conductor disposed on another surface of the dielectric substrate opposite to the first conductor layer,wherein an opening whose width in a direction perpendicular to a traveling direction of the electromagnetic wave for communication traveling through the dielectric layer is not less than 1/20 and not greater than ⅗
of a width in the direction perpendicular to the traveling direction of the electromagnetic wave for communication of the dielectric substrate is provided, the opening penetrating from the first conductor layer to the second conductor layer.

Abstract
A communication sheet (100) according to the present invention that transmits an electromagnetic wave for communication, includes a dielectric layer (120) including a dielectric substrate, a first conductor layer (110) including a mesh sheet-like mesh conductor disposed on one surface of the dielectric substrate; and a second conductor layer (130) including a sheet-like conductor disposed on another surface of the dielectric substrate opposite to the first conductor layer (110). The communication sheet (100) is provided which includes an opening whose width in a direction perpendicular to a traveling direction of the electromagnetic wave for communication traveling through the dielectric layer (120) is not less than 1/20 and not greater than ⅗ of a width in the direction perpendicular to the traveling direction of the dielectric substrate, the opening penetrating from the first conductor layer (110) to the second conductor layer.
