Patent ID: 8556182

Claim:
A card data carrier comprising: a first HF detection plate, consisting of an interposer having a chip with antenna connections, and of an antenna loop mechanically connected with the antenna connections, wherein the antenna loop is the sole coil of the HF detection plate; a second detection plate composed of a chip and an antenna arrangement coupled with the chip, said antenna arrangement comprising an inductive coupling loop which is connected with connectors of the chip, and which completely or partially encloses a region of the data carrier that is not electrically conductive, wherein said second detection plate is a UHF detection plate, wherein the antenna arrangement of the second detection plate that is coupled with the chip additionally comprises an amplifier antenna that is configured as an electrical antenna and increases the reading range in the remote field, wherein the coupling loop is inductively coupled with said amplifier antenna, and wherein the electrical antenna forms a component of an antenna of a detection plate for the LF or HF range, or is disposed in or on a storage sheath or holder of the card data carrier, wherein the electrical conductor of the electrical antenna has a course with at least one 90° deflection angle in which the coupling loop of the second detection plate is located.
