Title:
COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/066406
Kind Code:
A1
Abstract:
A technology is provided to realize two-dimensional communication using electro-magnetic waves. A communication device (10) has a first electrically conductive layer (20), a second electrically conductive layer (30) and a dielectric layer (40) held between the first and second electrically conductive layers (20, 30). First and second electrodes (112, 114) are closely electro-magnetically coupled to the first and second electrically conductive layers (20, 30) through the dielectric layer (40), respectively. A distance of the dielectric layer (40) is set shorter than a half wavelength of the electro-magnetic wave generated. An electro-magnetic wave to transmit signals is generated in a dielectric region by varying voltages applied between the first and second electrodes (112, 114). Shapes of the first and second electrodes (112, 114) are determined to reduce impedances between the first and second electrodes (112, 114) and the electrically conductive layers closely electro-magnetically coupled to them, respectively.
