15. A method for making a magnetic sheet for use with an antenna module, the method comprising:
-
disposing a protective layer on at least one of a top surface or a bottom surface of a magnetically permeable layer so as to form the magnetic sheet; and rotating a roller device in a first direction and a second direction upon an outer surface of the magnetic sheet so as to divide the magnetically permeable layer into a plurality of randomly shaped pieces such that the magnetic sheet is configured to affect a resonance frequency of the antenna module, at least one of the randomly shaped pieces not having a rectangular or triangular shape , the outer surface being adjacent to one of the top surface or bottom surface of the magnetically permeable layer, the roller device having a predetermined radius. - View Dependent Claims (16, 17)

18. A magnetic sheet comprising:
-
a magnetically permeable layer; a first protective layer; a second protective layer; in which the first protective layer is disposed on a first surface of the magnetically permeable layer and the second protective layer is disposed on a second surface of the magnetically permeable layer, the second surface being opposite the first surface, in which the magnetically permeable layer has a plurality of randomly shaped pieces on the first surface, at least one of the randomly shaped pieces not having a rectangular or triangular shape, and in which the magnetic sheet is configured to be usable with an antenna module and during operation the magnetically permeable layer affects a desired resonance frequency of the antenna module. - View Dependent Claims (19, 20)
