Title:
全天候型電波反射吸収体及びその組込構造体
Document Type and Number:
Japanese Patent JP4087438
Kind Code:
B2
Abstract:
The present invention provides an all-weather radio wave absorber having reflector capable of smoothly attenuating harmful microwave or millimeter wave from 400MHz to 100GHz generated from various electronic devices so that bad effects on human body or electronic device can be eliminated. The all-weather radio wave absorber having reflector comprises a laminated radio wave absorbing composite comprising a foamed upper radio wave absorber 1 with a rugged surface or a flat surface including conductive particles such as carbon particles, ferrite particles or the like in continuous foams 2 formed therein, one or more foamed intermediate planar radio wave absorbers 3 including conductive particles such as carbon particles 7, ferrite particles or the like in continuous foams 2 formed therein, a thin radio wave reflector 4 at the bottom, and a flexible cover for wrapping the laminated absorbers and reflector together. The laminated absorbing composite can absorb and attenuate radio waves from every direction, can reflect remaining radio waves by the reflector 4 and can absorb reflected radio waves by the absorber, so that static electricity generated on clothes is eliminated by the radio wave absorbing composite.
