Abstract (en)
[origin: WO2014111656A1] The invention relates to a method for the production of an object incorporating a contactless microcircuit, said method comprising steps consisting in: forming an antenna coil (AT1) in the form of a spiral on a first face of a substrate (TG4); securing the microcircuit to the substrate; on the substrate, forming first and second conductive pads (E2, E4) connected to inner and outer ends respectively of the spiral of the antenna coil; connecting the connection terminals of the microcircuit to third and fourth conductive pads (E2', E4'); and securing the microcircuit to the substrate, with the first and third conductive pads being positioned to face one another and the second and fourth conductive pads facing one another, such as to form two capacitors mounted in series with the antenna coil, the first or second conductive pad comprising a non-conductive window (1) which the microcircuit is positioned to face.
