Chip card and method of forming a chip card

A chip card, comprising:

• a chip card substrate;
• and
• an antenna structure comprising an insulated wire arranged in or over the chip card substrate 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 insulated wire comprises an insulated material coated around an electrically conductive material core;
• wherein the first antenna portion comprises a first antenna subportion arranged in a first direction and a second antenna subportion arranged in a second direction opposite to the first direction;
• wherein the first antenna subportion is laterally adjacent and horizontally parallel to the second antenna subportion, such that the at least some laterally adjacent insulated wire portions form a capacitor;
• and
• wherein the electrically insulating material of the at least some adjacent insulated wire portions is physically contacting each other.
