Abstract

In general, the invention relates to a method for manufacturing a wired antenna on a plastic sheet forming an inlet for smart card. The method includes affixing a wired antenna onto the plastic sheet, and affixing at least one metallic plate onto both ends of the wired antenna.

Claims

1. A method for manufacturing a wired antenna on a plastic sheet forming an inlet for smart card, wherein said method comprises:

affixing a wired antenna onto the plastic sheet, and

affixing at least one metallic plate onto both ends of the wired antenna.

2. The method of claim 1, further comprising:

creating a connection area in the at least one metallic plate, at each end of the wired antenna.

3. A method for manufacturing a smart card comprising:

affixing a wired antenna onto an inlet in the smart card,

affixing a first metallic plate onto both ends of the wired antenna,

creating connection areas in the first metallic plate, at each end of the wired antenna, and

connecting the electronic module to the connection areas, wherein the smart card comprises the inlet which hosts an antenna and an electronic module including a radio-frequency microcontroller, said electronic module being electrically connected to said antenna, said inlet being covered by at least one layer.

4. The method of claim 3, wherein creating the connection areas comprises milling a double cavity, involving a cutting of the metallic plate so as to form two connection areas at each end of the wired antenna.

5. The method of claim 3, wherein a second metallic plate is affixed onto each end of the wired antenna.

6. The method of claim 4, wherein the connection areas are positioned in a depth of the smart card in such a manner that they are located in the depth of a largest part of the double cavity.

7. The method of claim 6, wherein the electronic module is connected to the connection areas by one selected from a group consisting of thermo-compression welding, conductive glue and an anisotropic glue.

8. The method of claim 4, a further comprising drilling holes from a largest part of the double cavity.

9. A smart card comprising:

an inlet which hosts a wired antenna and an electronic module including a radio-frequency microcontroller,

said electronic module being electrically connected to said wired antenna,

said inlet being covered by at least one layer,

wherein both ends of the wired antenna comprise a metallic plate forming connection areas for connecting the electronic module.

10. The smart card of claim 9, wherein the smart card is a dual-interface smart card, wherein the wired antenna is affixed onto the inlet in the smart card, wherein each of the metallic plates is affixed onto both ends of the wired antenna, and wherein connection areas are located in the metallic plate, at each end of the wired antenna.

11. The smart card of claim 9, wherein the smart card is a contactless smart card, wherein the wired antenna is affixed onto the inlet in the smart card, wherein each of the metallic plates is affixed onto both ends of the wired antenna, and wherein connection areas are located in the metallic plate, at each end of the wired antenna.
