Procedimiento de fabricación de un dispositivo que comprende un circuito de radiofrecuencia, y dispositivo correspondiente

摘要

The method involves producing a module (20a) comprising sets of upper and lower contact pads. The two sets of contact pads are connected by an integrated circuit and a capacitor forming component e.g. radiofrequency transponder microcircuit such as radiofrequency identification tag microcircuit, respectively. Ends (31, 32) of a common antenna (24) are fixed on the two sets of contact pads and ends of a relay antenna are fixed on each of the sets of contact pads, where the common and relay antennas are centered and/or positioned inside one another. An independent claim is also included for a radiofrequency transponder microcircuit integrated device comprising an antenna.
