Abstract
A detector of articles comprising a contactless RF-ID type label comprises at least one antenna formed by N loops and M turns, together being greater than or equal to 1, characterized in that at least one of the turns is made up of at least two complementary segments, the two segments not being coplanar. The present invention also relates to an identification system comprising the detector and to a method for the production of the detector.

- 17. A detector of articles comprising a contactless label of the RFID type, said detector comprising at least one antenna formed of N loops and M turns, M and N being integers greater than or equal to 1, wherein at least one of the turns consists of at least two complementary segments, the two complementary segments not being coplanar, and being arranged so that an addition of one of said complementary segments starting from an end thereof to another of said complementary segments constitutes a turn, and each segment is present on one of two different substrate layers.
- 24. A system for the identification of articles comprising contactless labels of the RFID type, comprising an intermediate element and an antenna formed from several turns, at least one of the turns being constituted by at least two complementary segments, the at least two segments not being coplanar, and said intermediate element comprising a thin casing comprising an electrical circuit.
