  • Patent number: 10380477
    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.

  • Publication number: 20170246844
    Abstract: A chip card substrate is provided, which includes a plurality of layers. The plurality of layers includes a first polymer layer including a first polymer material, a second polymer layer disposed over the first polymer layer and a second polymer material different from the first polymer material. The plurality of layers further includes a third polymer layer disposed over the second polymer layer and including the first polymer material. The second polymer layer includes a plurality of cutouts at an edge of the second polymer layer so that the first polymer material of the first polymer layer and of the third polymer layer form a coupling through the plurality of cutouts.
