    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.
