Abstract
Provided is a data carrier comprising at least a first metallic layer, at least one electronic module, at least one antenna, and at least a second metallic layer. The second metallic layer is arranged after the first metallic layer with respect to an extension direction (E). The antenna is in connection with the electronic module. The first metallic layer is a continuous metallic layer delimiting a recess, and wherein the electronic module is at least partially arranged within said recess. Other embodiments disclosed.

A data carrier (1, 1′, 1″) comprising:
- at least a first metallic layer (2, 2′, 2″);
- at least one electronic module (4, 4′, 4″);
- at least one antenna (5, 5′, 5″);
- and
- at least a second metallic layer (3, 3′, 3″),
- wherein the second metallic layer (3, 3′, 3″) is arranged after the first metallic layer (2, 2′, 2″) with respect to an extension direction (E), and
- wherein the antenna (5, 5′, 5″) is in connection with the electronic module (4, 4′, 4″),
- characterized in that the first metallic layer (2, 2′, 2″) is a continuous metallic layer delimiting a recess (6, 6′, 6″), wherein the electronic module (4, 4′, 4″) is at least partially arranged within said recess (6, 6′, 6″) and wherein the data carrier (1, 1′, 1″) further comprises at least one shielding element (12, 12′, 12′a, 12″) that is configured to shield the antenna (5, 5′, 5″) and/or the electronic module (4, 4′, 4″) from magnetic fields.
A secure article comprising or consisting of at least one data carrier (1, 1′, 1″) comprising:
- at least a first metallic layer (2, 2′, 2″);
- at least one electronic module (4, 4′, 4″);
- at least one antenna (5, 5′, 5″);
- and
- at least a second metallic layer (3, 3′, 3″),
- wherein the second metallic layer (3, 3′, 3″) is arranged after the first metallic layer (2, 2′, 2″) with respect to an extension direction (E), and
- wherein the antenna (5, 5′, 5″) is in connection with the electronic module (4, 4′, 4″), characterized in that the first metallic layer (2, 2′, 2″) is a continuous metallic layer delimiting a recess (6, 6′, 6″), wherein the electronic module (4, 4′, 4″) is at least Partially arranged within said recess (6, 6′, 6″) and wherein the data carrier (1, 1′, 1″) further comprises at least one shielding element (12, 12′, 12′a, 12″) that is configured to shield the antenna (5, 5′, 5″) and/or the electronic module (4, 4′, 4″) from magnetic fields,
- wherein the secure article preferably is a smart card.
A method of producing a data carrier (1, 1′, 1″), wherein the method comprises the steps of:
- Providing at least a first metallic layer (2, 2′, 2″);
- Providing at least one electronic module (4, 4′, 4″);
- Providing at least one antenna (5, 5′, 5″);
- and
- Providing at least a second metallic layer (3, 3′, 3″),
- wherein the second metallic layer (3, 3′, 3″) is arranged after the first metallic layer (2, 2′, 2″) with respect to an extension direction (E), and
- wherein the antenna (5, 5′, 5″) is in connection with the electronic module (4, 4′, 4″),
- characterized in that the first metallic layer (2, 2′, 2″) is a continuous metallic layer delimiting a recess (6, 6′, 6″), wherein the electronic module (4, 4′, 4″) is at least partially arranged within said recess (6, 6′, 6″) and wherein the data carrier (1, 1′, 1″) further comprises at least one shielding element (12, 12′, 12′a, 12″) that is configured to shield the antenna (5, 5′, 5″) and/or the electronic module (4, 4′, 4″) from magnetic fields.
