Title:
ALL-WEATHER RADIO WAVE REFLECTOR/ABSORBER AND ITS ASSEMBLING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2006/112001
Kind Code:
A1
Abstract:
There is provided an all-weather radio wave reflector/absorber capable of smoothly attenuating hazardous radio waves from microwave to millimetric wave of 400 MHz-100 GHz generated from various electric apparatuses and eliminating affect on human body or other electronic apparatus. The all-weather radio wave reflector/absorber includes a surface radio wave absorber (1) containing conductive granular material such as carbon particles (7) and ferrite particles in a continuous foamed portion (2) of only irregular foam or planar foam, an intermediate planar radio wave absorber (3) containing conductive granular material such as carbon particles (7) and ferrite particles in one layer or more of continuous foamed portion (2) of foam, and a thin layer of bottom face radio wave reflecting material (4) which are overlaid in layers and entirely wrapped up in a soft cloth so that radio waves from all directions can be absorbed, attenuated, reflected on the bottom face radio wave reflecting material (4) and absorbed by the absorber, and static electricity stored on the human body and clothes can be discharged.
