    摘要： A booster antenna (BA) for a smart card comprises a card antenna (CA) component extending around a periphery of a card body (CB), a coupler coil (CC) component at a location for an antenna module (AM), and an extension antenna (EA) component contributing to the inductance of the booster antenna (BA). At least a portion of the coupler coil (CC) component may have a sense which is opposite to a sense of at least a portion of the card antenna (CA) component. At least a portion of one of the components may be interleaved with (i) a portion of another component, or (ii) another portion of the same component. A capacitive extension (CE) may extend from at least one of the card antenna (CA), coupler coil (CC) and extension antenna (EA) components.

    摘要： A dual-interface metal hybrid smartcard comprising a plastic card body (CB); a metal slug (MS) disposed in the card body; and a booster antenna (BA) disposed in the card body. The metal slug may have a surface area which is at least 50% of a surface area of the card body, and may comprise titanium or alloys thereof. A antenna chip module (AM) having an antenna (MA) and contact pads (CP) may be disposed in an opening of the card body. The metal slug may comprise two or more separate metal slug components (MS-1, MS-2), which may overlap one another or which may be disposed at different locations in the card body (CB), without overlapping one another. The first metal slug component (MS-1) may be disposed around a peripheral portion of the card body (CB) as an “open loop” discontinuous metal frame around (external to) the booster antenna (BA). The second metal slug component (MS-2) may be disposed internal to the card antenna (CA) component of the booster antenna (BA).

    摘要： A dual interface (DI) smart card (100) comprising a chip module (CM), a module antenna (MA), a card body (CB) and a card antenna (CA) having two windings (D,E) connected with reverse phase as a “quasi-dipole”. Capacitive stubs (B,C) connected with an antenna structure (A) of the module antenna (MA). The module antenna (MA) overlaps only one of the windings (D or E) of the card antenna (CA). The card antenna (CA) may be formed from one continuous wire. Ferrite (156) shielding the module antenna (MA) from contact pads (CP) and for enhancing coupling between the module antenna (MA) and the card antenna (CA).
