Abstract

An RFID transponder comprises an electronic assembly and an antenna assembly. The electronic assembly is a multi-layer film body having one or more electrically conducting functional layers and one or more electrically semiconducting functional layers. The antenna assembly has one or more electrically conducting functional layers, of which one is an antenna coil. In a first region and a second region of the body a respective one of the one or more electrically conducting functional layers forms respective first and second capacitor plates. In addition, in the first region and the second region of the body a respective one of the one or more electrically conducting functional layers of the antenna assembly is formed as a third and a fourth capacitor plate so that the electronic assembly and the antenna assembly are electrically coupled by capacitors formed respectively by the first and third and by the second and fourth capacitor plates.
