Title:
SHEET STRUCTURE FOR COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2009/157095
Kind Code:
A1
Abstract:
A sheet structure for performing communication by making an electromagnetic wave propagate is composed of a planar base material having a dielectric constant of 1.0-15.0 at a frequency of 800 MHz to 10 GHz. Portions where a conductor (A) exists and does not exist are provided on one side of the base material, and a conductor (B) exists on the other side of the base material over 90% or more of the entire surface. The sheet structure for communication exhibits extremely excellent communication performance and two-dimensional communication is made possible by using the sheet structure for communication.
