Abstract

A chip card is provided. The chip card may include a chip card substrate and an antenna structure disposed in or over the chip card substrate, the antenna structure including a wire arranged to form a first antenna portion configured to contactlessly couple to a chip card external device and a second antenna portion configured to couple to a chip antenna, wherein the wire may include an electrically conductive material coated with an electrically insulating material, wherein the wire of the first antenna portion may be arranged such that a direction of laying progress of the wire of at least some adjacent wire portions are opposite to each other, such that the at least some adjacent wire portions may form a capacitor, wherein the isolation material of the at least some adjacent wire portions may be physically contacting each other.
