Title:
COMMUNICATION SHEET AND ELECTRIC POWER TRANSMISSION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/137404
Kind Code:
A1
Abstract:
A conductor layer (100) is electrically conductive and comprises a first mesh region where apertures (120) are formed in a mesh shape. A conductor layer (200) is electrically conductive and comprises a second mesh region where apertures (220) are formed in a mesh shape. An insulator layer (300) is insulative and is disposed between the conductor layer (100) and the conductor layer (200). A communication sheet (1000) allows a radio wave supplied from a first communication device to percolate from the apertures (120) to form a first percolation region on the surface of the conductor layer (100), and allows the radio wave to percolate from the apertures (220) to form a second percolation region on the surface of the conductor layer (200). The communication sheet (1000) relays communication between the first communication device and a second communication device that is disposed in the first or second percolation region.
