A transponder to be fitted in or on a surface of an article which is substantially formed of a rubber product, in particular a transponder to be fitted in a tire, has a dipole antenna. The antenna length L, wherein air is exclusively present as the transmission medium, is calculated with the equation L=0.5&#xd7;c/f, wherein c is the speed of light and f is the transmission frequency. In order to achieve a long transmission range, the transponder in the rubber product has an antenna length Lbetween 0.45&#xd7;Land 0.90&#xd7;L, preferably substantially between 0.61&#xd7;Land 0.71&#xd7;L.

Transponder configuration, tire including a transponder, and method of producing a tire having a transponder

The invention is directed to a transmitting and/or receiving unit for building into an elastic structure. The transmitting and receiving unit includes one or more electronic circuits or circuit elements and, if needed, sensors and/or signal elements assigned thereto. The transmitting and/or receiving unit has one or several antennas connected to the electronic circuit. The antenna includes one or several filaments which are so arranged in the surface or in space that the main directions of the stresses and forces, which occur within the surrounding elastic structure/matrix, essentially intersect or cross the filament axes.
