Radio wave absorber

Abstract

Abstract PURPOSE:To realize a radio wave absorber which has a small size, a flat surface, wide band and satisfactory oblique incident characteristic by burying the absorber having scattering effect made of high loss medium in a medium formed by laminating nonwoven fabrics made of resin fiber, conductive fiber. CONSTITUTION:15 sheets of nonwoven fabrics formed by mixing conductive fiber 4 on a metal plate 5 are so inserted that high loss sheets 3 are sequentially inserted between first to tenth layers from the plate side of a laminate 1 so as to be reduced in shape thereby to construct a scattering type absorber 2. The sheet 3 employs nonwoven fabric mixed with the fiber 4. In this case, a radio wave absorber having a small size, a flat surface, wide band and satisfactory oblique incident characteristic can be designed by regulating the length of the fiber 4 of the fabric, mixing ratio, thickness of the laminated layer, the shape, loss of the absorber 2.
