Title:
RADIO WAVE ABSORBER AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2006179671
Kind Code:
A
Abstract:

To provide a radio wave absorber which has enough reflection damping ability for preventing communication jamming such as by reflection of an electromagnetic wave, can be made thin and lightweight, and has a damping characteristic in a wide band; and to provide a manufacturing method of the radio wave absorber.

The radio wave absorber has an entire conductor layer 11 consisting of a conductor, a first dielectric layer 12 consisting of one layer or a number of layers, a linear pattern resistance layer 13 having a linear pattern consisting of a high resistance conductor which has higher resistivity than the entire conductor layer 11, second dielectric layers 14, 15 consisting of one layer of a number of layers and a pattern layer 16 having a plurality of patterns consisting of a conductor.
