Document Type and Number:
WIPO Patent Application WO/2014/126394
Kind Code:
A1
Abstract:
The present invention relates to an electromagnetic wave absorbing sheet and an antenna module having the same, in which a first electromagnetic wave absorbing sheet and a second electromagnetic wave absorbing sheet are laminated on one surface of an antenna unit in a manner that they overlap each other, and the first electromagnetic wave absorbing sheet and the second electromagnetic wave absorbing sheet have different magnetic permeabilities. Therefore, the present invention can simplify the assembly process, remarkably degrade the external appearance defect rate, improve productivity, and improve both the short-range wireless communication function and the wireless charging function.
