Abstract: An electromagnetic interference (“EMI”) sheet attenuator includes a planar conductive layer, a first flexible substrate and a second flexible substrate. The first flexible substrate overlies the metal backing layer and including a conductive pattern on a surface of the first flexible substrate. The second flexible substrate overlies the first flexible substrate and also includes the conductive pattern. The conductive pattern on the second flexible substrate is aligned with the conductive pattern on the first flexible substrate.
