Laminierte Platte mit geringem Reflexionsvermögen für Funkwellen

摘要

The matter of concern is the reflection of a radio wave such as a television broadcast wave from a laminated panel having a substrate (10) low in reflectance for radio waves and a layer (12) relatively high in reflectance for radio waves. The reflection is greatly reduced by dividing the reflective layer (12) into a plurality of discontinuous segments (12a) by a series of relatively narrow slits (14) such that the width (L) of each segment (12a) in the direction parallel to the direction of the electric field of the radio wave is not greater than 1/3 of the wavelength of the radio wave. The invention is suitable for application to a heat reflecting glass with a heat reflecting film having a surface resistivity below about 500 OMEGA / &squ& , and in that case it is preferable that the width of each segment of the heat reflecting film is not greater than 1/20 of the wavelength.
