Abstract
The invention concerns a support for an antenna, such as a RFID antenna, used in a flexible cover, for example a passport cover, whereby said antenna is surrounded by material of said cover. Said support comprises means for disconnecting the antenna from the surrounding material so that bending stress applied to said material is not transferred to the antenna. The support may be used in different products, for example in passports.
Claims19
A functional laminate, comprising:
- a plurality of layers of support material bonded together, an antenna having a first end and a second end adapted to be connected to a RFID chip, said antenna having at least one winding embedded in the surrounding support material, and means for separating at least one discrete portion of said antenna from the surrounding material, said at least one discrete portion of said antenna located between the first and second ends of the antenna, and wherein said means comprises at least one cavity surrounding said at least one discrete portion of the antenna such that, in said at least one cavity, the at least one discrete portion of the antenna is fully separated from the surrounding material.
A functional laminate, comprising:
- a plurality of layers of material bonded together, an antenna having a first end and a second end adapted to be connected to a RFID chip, said antenna having at least one winding embedded in the material, and means for separating at least one discrete portion of said antenna from the surrounding material, said at least one discrete portion of said antenna located between the first and second ends of the antenna, wherein said means comprises at least one release layer positioned in direct proximity of said at least one discrete portion of the antenna, and wherein said release layer mechanically disconnects said at least one discrete portion of the antenna from the surrounding support material.
