Abstract:
1. An RF device comprising a processing circuit, a first antenna, a substrate having upper and lower faces, and an electromagnetic expansion, said electromagnetic expansion comprising a third antenna, a fourth antenna and an electrical network connected to said third and fourth antennas; wherein said first antenna is configured to be magnetically or electromagnetically coupled to said fourth antenna and said third antenna is configured to be magnetically or electromagnetically coupled with a second antenna, the electromagnetic expansion being configured to generate a replica of each electromagnetic signal received by said third antenna; wherein the third and fourth antennas include conductive lines formed on the upper face of the substrate and at least one crossing point at which a first one of the conductive lines has an interruption point defining two facing ends, said facing ends being capacitively coupled, and the third and fourth antennas further include a second one of the conductive lines having a transverse connection portion extending between said facing ends of the first one of the conductive lines to provide a conductive electrical connection of a first segment of the second one of the conductive lines to a second segment of the second one of the conductive lines.
