Abstract:
1. An RFID transponder comprising: an antenna assembly comprising one or more electrically conducting functional layers, one of which functional layers forming an antenna coil; and an electronic assembly comprising a multi-layer film body forming an integrated electronic (IC) circuit coupled to the antenna, the IC circuit comprising one or more electrically conducting functional layers and one or more electrically semiconducting functional layers; one of the one or more electrically conducting functional layers in a first region of the body comprises an electrode layer forming one or more electrodes of at least one of an organic field effect transistor or organic diode, and a first capacitor plate, all forming an integral component part of the integrated electronic circuit; one of the one or more electrically conducting functional layers in a second region of the body forms an electrode layer of the electronic assembly, in which electronic assembly one or more electrodes are formed for the one or more organic field effect transistors or organic diodes and further formed as a second capacitor plate forming an integrated component part of the integrated electronic circuit; one of the one or more electrically conducting functional layers of the antenna in the first region of the body forming a third capacitor plate; one of the one or more electrically conducting functional layers of the antenna in the second region forming a fourth capacitor plate, wherein the electronic assembly and the antenna assembly are electrically coupled by capacitors formed by the first, second, third and fourth capacitor plates.
