Method for making contactless portable devices with dielectric bridge and portable devices

A method for manufacturing contactless portable objects having an integrated circuit, which comprises the following steps:

• providing a dielectric antenna substrate which carries an antenna circuit and has at least one turn and two contact terminals, wherein a first contact terminal is interior to the antenna circuit, and a second contact terminal is exterior to said antenna circuit;
• providing a bridge which comprises a dielectric bridge substrate, a chip having an integrated circuit and a circuit for connecting said chip to the antenna circuit;
• and
• placing said bridge provided with said chip onto said dielectric antenna substrate, so that
• the bridge forms an electrical connection between said chip and said antenna circuit, and
• the chip is positioned, while being protected between the bridge substrate and the antenna substrate or being incorporated within said antenna substrate, at a position offset with respect to the turns of the antenna.
