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.

A chip card module is provided. The chip card module may include a carrier having a first side and an opposite second side, a chip arranged over the carrier, the chip having a first chip contact, a first and a second antenna contact formed over the first side, a metal-free area formed over the first side between the first antenna contact and the second antenna contact, wherein the metal-free area extends between a first edge portion and a second edge portion of the carrier, and a first chip connection electrically connecting the first chip contact to the first antenna contact, wherein the first chip connection is at least partially arranged over the second side in a region opposite the metal-free area.
