    摘要: A data carrier (1) comprises at least one carrier body (2), at least one electronic module (3), at least one antenna (4), and at least one metallic layer (5). The electronic module (3) is at least partially arranged in the carrier body (2). The antenna (4) is in connection with the electronic module (3). The metallic layer (5) comprises at least one recess (6), and the antenna (4) comprises an electrically conducting wire (7) that is at least partially arranged in the recess (6). At least part of the metallic layer (5) is part of the antenna (4).

    摘要: A media card (200 or 300) with an tunable inductive antenna pattern (203) includes an area (204) configured for receiving a wireless chip (306a, 306b, or 306d) operating at one of several given frequencies and an antenna with an antenna pattern printed on a core layer (202) and printed on the area configured for receiving the wireless chip, where the antenna pattern includes one or more selectable conductive extension segments (206a-206g). In some embodiments, the one or more selectable conductive extension segments are selectively removed to tune the antenna for a frequency for the wireless chip operating at one of several given or predetermined frequencies.

    摘要: A card (200) having processed areas includes a core layer (104), an antenna pattern (102) on the core layer, and one or more bump-out areas (110) of the antenna pattern having a threshold distance towards a process boundary, where the card passes a continuity test if a cutting or a punching or a milling process fails to create an open circuit at the bump-out areas. The card fails a continuity test if the cutting or the punching or the milling processes creates the open circuit at the bump-out areas.
