Sheet Member for Improving Communication, and Antenna Device and Electronic Information Transmitting Apparatus Provided Therewith
First Claim
1. A sheet member for improving communication used when performing wireless communication using an antenna element in a vicinity of a communication jamming member having a portion made of a conductive material, the sheet member being disposed between the antenna element and the communication jamming member, and comprising:
- a pattern layer in which a conductive pattern portion is formed, the conductive pattern portion resonating with an electromagnetic wave used for wireless communication, storing electromagnetic energy, forming electromagnetic coupling with the antenna element, and transferring the stored electromagnetic energy to the antenna element; and
a storage layer that is interposed between the pattern layer and the communication jamming member, that is made of a non-conductive dielectric layer and/or magnetic layer and that collects energy of electromagnetic waves used for wireless communication to pass therethrough, thereby improving a communication distance by wireless communication.

Abstract
In one embodiment of the present invention, a conductive pattern portion formed in a pattern layer functions as an antenna, and, when electromagnetic waves at a predetermined frequency arrive, resonance occurs, and an electromagnetic wave of a specific frequency is introduced into a sheet member. As to the sheet member having the pattern layer, even in a small and thin sheet member, the phase of reflected waves from the reflection area can be adjusted, and thus an area having high electric field intensity due to interference between reflected waves from the reflection area and arriving electromagnetic waves can be set in the vicinity of the antenna element. When the sheet member is disposed between an antenna element and a communication jamming member, an electromagnetic field is generated around the conductive pattern portion, and an electromagnetic energy is supplied from the conductive pattern portion to the antenna element, and therefore receiving power of the antenna element can be increased. Accordingly, wireless communication can be suitably performed.
