METHOD OF PRODUCING RADIOFREQUENCY IDENTIFICATION ELEMENTS AND RADIO­FREQUENCY IDENTIFICATION ELEMENTS CAPABLE OF BEING OBTAINED BY SUCH A METHOD

摘要

The invention relates to a method of producing, by vacuum deposition of at least one conducting material on a supporting means, radiofrequency identification elements as well as to radiofrequency identification elements that can be obtained by implementing such a method. The present invention is directed to a method of production allowing low-cost fabrication of radiofrequency identification elements which have high-performance and are also discrete. To achieve this, the invention provides for the use of a vacuum deposition technique for producing the antenna on a support means previously covered with a bonding coat, such as a layer of varnish. More precisely, the subject of the invention is a method of producing at least one radiofrequency identification element consisting in producing at least one antenna (8) on a support means (2) by vacuum deposition of at least one conducting material (10) on a receiving surface (2a) of the support means (2), characterized in that at least a part of the receiving surface (2a) is previously covered with a bonding coat (6).
