Title:
SHEET BODY FOR IMPROVING COMMUNICATION, ANTENNA DEVICE PROVIDED WITH SUCH SHEET BODY AND ELECTRONIC INFORMATION TRANSMITTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2007/046527
Kind Code:
A1
Abstract:
A conductive pattern (22) formed on a pattern layer (15) operates as antenna.
When an electromagnetic wave of a prescribed frequency arrives, resonance phenomenon
is exhibited, and the electromagnetic wave of a specific frequency is introduced
into a sheet body (10). Since the sheet body (10) having the pattern layer (15)
can adjust the phase of a reflection wave from a reflection area, even the sheet
body is small and thin, and an area having a high electric field intensity can be
set in the vicinity of the antenna element by interference of the reflection wave
from the sheet body and the coming electromagnetic wave. An electromagnetic
field is generated in the periphery of the conductive pattern (22) by arranging
the sheet body (10) between the antenna element (51) and the communication disturbing
member (57), and electromagnetic energy is supplied from the conductive pattern
to the antenna element (51). Thus, receiving power of the antenna element (51)
is increased and wireless communication can be suitably performed.
