Abstract
The provided is an ultra-wideband electromagnetic wave absorber having a hexagonal double layer structure, and in the ultra-wideband electromagnetic wave absorber, the first conductive pattern disposed on the top of the first dielectric layer and the second conductive pattern disposed on the top of the second dielectric layer are arranged in an up-down double layer structure, thereby expanding the electromagnetic wave absorption bandwidth, and even when applied to a corner or a curved structure forming 60° or 120° by hexagonal unit cells, the unit cells can be periodically arranged at the same interval. In addition, since dielectrics with a difference of less than 10% in dielectric constant in a vacuum state have a relatively low specific gravity, the overall weight can be made very light by using such dielectrics in the first dielectric layer and the second dielectric layer.
