Title:
RADIO WAVE ABSORPTION SHEET
Document Type and Number:
Japanese Patent JP2018056492
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a radio wave absorption sheet capable of properly absorbing radio waves of high frequencies as high as or higher than a millimeter wave band and capable of being easily handled.SOLUTION: A radio wave absorption sheet comprises a radio wave absorption layer 1 having flexibility, which includes a particulate radio wave absorption material 1a and a resin binder 1b. The radio wave absorption material is magnetic iron oxide which magnetically resonates at a frequency band as high as or higher than a millimeter wave band. An axis of easy magnetization of the radio wave absorption material is subjected to magnetic field orientation in one in-plane direction of the radio wave absorption sheet.SELECTED DRAWING: Figure 1
