Abstract

An RFID transponder antenna has a carrier substrate and an auxiliary substrate. The carrier substrate is provided with a contact point for a first connection to an integrated circuit, and a first conductor path including at least two coil turns. A first end of the path forms a contact terminal for a second connection to the integrated circuit. The other end forms a connection point for an electrical connection to a second conductor path. The second path on the auxiliary substrate forms a bridge over the coil turns. The second conductor path has one end connected to the contact point, and another end connected to the connection point providing a permanent connection between the auxiliary substrate and/or the first conductor path, and the carrier substrate and/or second conductor path; the permanent connection being formed at least at one point lying between both ends of the auxiliary substrate.
