Title:
RADIO WAVE ABSORPTION STRUCTURE
Document Type and Number:
Japanese Patent JP2020009829
Kind Code:
A
Abstract:
To provide a radio wave absorption structure which has highly efficient radio wave absorption characteristics for a plurality of frequencies and can be manufactured relatively easily and thinly.SOLUTION: A radio wave absorption structure includes a resonance layer 11 that is provided on the surface such that radio waves are incident from the outside, and in which a plurality of patch conductors having individual resonance frequencies are arranged in a predetermined periodic pattern, a dielectric layer 12 for multiple reflection of radio waves resonated by the resonance layer 11, and a reflective conductor layer 13 that reflects radio waves incident from the dielectric layer 12 to the dielectric layer 12 side.SELECTED DRAWING: Figure 1
