Abstract
This invention relates to an electromagnetic wave absorption sheet and an antenna module having the same, wherein a first electromagnetic wave absorption sheet and a second electromagnetic wave absorption sheet are stacked to overlap each other on one surface of an antenna unit, and the first and the second electromagnetic wave absorption sheet have different permeabilities, thereby simplifying the assembly process, significantly decreasing the defect of an outer appearance, increasing productivity, and enhancing both near field wireless communication performance and wireless power charging performance.
