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.

Abstract: A radio frequency device comprises a radio frequency transponder having a radio frequency circuit and a radio frequency antenna, and a sensor conductively connected to the radio frequency antenna so that a measurement can be retrieved from the sensor by communicating with the transponder. The radio frequency antenna comprises a first portion which is used primarily for receiving and/or sending of radio frequency signals, and a second portion which is used primarily for conductively connecting the sensor to the first portion of the radio frequency antenna and which enables placing the sensor in a spaced-apart spatial relation to the first portion of the radio frequency antenna.
