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 (AT4) in the form of a spiral from a first face of a substrate (TG4); on the substrate, forming first and second conductive pads (E16, E17) 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 (EM1, EM1'); 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, the first to fourth conductive pads forming two capacitors mounted in series with the antenna coil, the antenna coil and the first and second conductive pads being formed by insertion of a conductive wire into the substrate.
