An antenna for transfer of information or energy is described. The antenna includes an electrically conductive first layer having a width in a thickness direction of the antenna and extending longitudinally along a length of the first layer between first and second longitudinal ends of the first layer, and an electrically insulative thermally conductive second layer bonded to the first layer along the length of the first layer. The first and second layers are wound to form a plurality of substantially concentric loops. A width and a length of the second layer are substantially co-extensive with the respective width and length of the first layer so as to expose opposing longitudinal edge surfaces of the first layer along the length of the first layer. Coils and assemblies useful for making coils are also described.
An antenna for transfer of information or energy, comprising:
A coil comprising a multilayer film wound to form a plurality of substantially concentric loops, the multilayer film comprising:
A coil comprising a plurality of substantially concentric loops, each loop comprising a metal layer substantially concentric with an electrically insulative thermally conductive layer and an adhesive layer, the metal layer, the thermally conductive layer and the adhesive layer substantially co-extensive with each other in width and length, wherein in a plan view, the coil comprises a regular pattern of substantially parallel grooves extending across at least a plurality of adjacent loops in the plurality of substantially concentric loops.
