Abstract
A magnetic-guiding laminate is used to improve wireless communication between a transmitter and a receptor disposed on a substrate, regardless of the substrate materials. The laminate can comprise one or more layers of magnetic or non-magnetic material with different magnetic property. For example, the laminate can comprise a paramagnetic layer disposed on a diamagnetic layer, where the paramagnetic layer attracts the magnetic field toward the RFID antenna, and the diamagnetic layer prevents the magnetic field from dispersing in the substrate. Alternatively, the laminate can comprise multiple paramagnetic layers, wherein at least two layers have different magnetic properties, such as different permeability values.
