Abstract
Deformable magnetic antennas are provided to include a plurality of flexible magnetic antenna layers stacked to form a layered magnetic antenna structure that is bendable. Each flexible magnetic antenna layer includes a magnetic material that confines a magnetic field to concentrate a magnetic flux of the magnetic field inside the magnetic antenna layer. A lubricating material is applied between adjacent flexible magnetic antenna layers to allow adjacent magnetic layers to move relative to one another when the layered magnetic antenna structure is bent so as to reduce a stress in each flexible magnetic antenna layer caused by bending the layered magnetic antenna structure.
