Title:
RADIO SHIELDING BODY
Document Type and Number:
WIPO Patent Application WO/2007/007896
Kind Code:
A1
Abstract:
A radio shielding body characterized by comprising a regulating layer for creating
an environment that stabilizes, in terms of radio wave, incoming radio waves/electromagnetic
waves, and resonating layer that is formed by arranging linear or the like conductors
resonating with selected specific-frequency radio waves/electromagnetic
waves on a resin sheet, a reinforced plastic sheet, a nonwoven fabric, paper and
the like and is attached to the regulating layer, whereby the regulating layer
designed to have a constant permittivity with a certain thickness is used to regulate
and keep the speed and the wavelength of a radio wave to/at specified designs so
as to be able to constantly shield a radio wave with a designed frequency equivalent
to a radio wave with a specific frequency in a radio wave environment thus obtained.
