  • Sheet member for improving communication, and antenna device and electronic information transmitting apparatus provided therewith
    Patent number: 8564472
    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.
