Abstract
An antenna comprises: a first terminal; a second terminal; and a winding, having an inductance, comprising a plurality of turns and connected between the first and second terminals such that a change in magnetic flux linking the winding generates a corresponding voltage between said terminals. The winding comprises a conductive element connected to the first and second terminals and extending around said turns from the first terminal to the second terminal and having a thickness not exceeding X μm along a length of the conductive element from the first to the second terminal and a width not exceeding X μm along said length, where X is less than or equal to 10, whereby said conductive element is substantially non-visible to a naked human eye.
