Title:
RADIO WAVE ABSORPTION SHEET
Document Type and Number:
Japanese Patent JP2022135025
Kind Code:
A
Abstract:
To provide a radio wave absorption sheet that can absorb a radio wave in a predetermined frequency in both a reflected wave on a surface of the radio wave absorption sheet and a transmitted wave transmitting through the radio wave absorption sheet.SOLUTION: A radio wave absorption sheet is obtained by sequentially laminating a resistance coating 1, a dielectric layer 2, and a reflective layer 3 and forming them into a sheet. The reflective layer 3 is formed as a closed loop resonator in which a plurality of closed loops 3a formed of conductive material are arranged side by side in a two-dimensional direction in a main surface direction of the radio wave absorption sheet.SELECTED DRAWING: Figure 2
