COMPOSITE RADIO WAVE ABSORBER

摘要

Provided is a radio wave absorber having an excellent radio wave absorption property of a return loss of 20 dB or more in a wide frequency band from 30 MHz to 20 GHz. A composite radio wave absorber is provided with a magnetic absorber plate, a cross-shaped radio wave absorber installed on the magnetic absorber plate, and a small-sized radio wave absorber installed in a space partitioned by a dielectric lossy material plate of the cross-shaped radio wave absorber on the magnetic absorber plate. The small-sized radio wave absorber has a multilayered structure provided with plural radio wave absorbing layers with a low dielectric constant layer interposed therebetween in a direction perpendicular to the magnetic absorber plate.
