A wearable device including an antenna structure, a chip having a receiver which is electrically coupled to the antenna structure and is configured to receive radio signals by means of the antenna structure, and a trigger device which is arranged in or on the wearable device, which device comprises electrically conductive material and which is configured to trigger foreign object detection in a wireless energy charger in accordance with a wireless charging standard for wirelessly charging an electronic device by means of taking up load from radio waves emitted by the wireless energy charger.

Wearable device, smart card and system

According to one embodiment, a chip card is described including a chip, an antenna, a coupling structure configured to transmit energy from the antenna to the chip and a control element configured to control, depending on a field strength of a magnetic field to which the chip card is exposed, at least one of the resonance frequency of the antenna, the quality factor of the antenna and an energy transmission efficiency of the coupling structure.

Chip card and control element

In various embodiments, a booster antenna structure for a chip card is provided, wherein the booster antenna structure may include a booster antenna; and an additional electrically conductive structure connected to the booster antenna.

Booster antenna structure for a chip card

In various embodiments, a chip card contact array arrangement is provided, having a carrier, a plurality of contact arrays which are arranged on a first side of the carrier, an electrically conductive structure which is arranged on a second side of the carrier, which is arranged opposite the first side of the carrier, a first plated-through hole and a second plated-through hole, wherein the first plated-through hole is coupled to the electrically conductive structure, a connecting structure which is arranged on the first side of the carrier, wherein the connecting structure connects the first plated-through hole to the second plated-through hole, the connecting structure having a longitudinal extent which runs parallel to a direction in which a contact-connection device on a reading device is moved relative to the plurality of contacts.
