Abstract
The invention relates to an RFID transponder which can be operated passively. It is the object of the invention to provide RFID transponders which can be operated passively in the far field, this means over distances of at least 15-20 cm, and which can be manufactured with reduced effort and costs in miniaturized form. In the RFID transponder in accordance with the invention, at least one antenna and one integrated RFID circuit are present on a substrate, The at least one antenna is in this respect included in the form of a dipole antenna and/or patch antenna in the same silicon block, as the substrate, as the integrated circuit. The at least one antenna is in this respect arranged at a minimum distance from the integrated RFID circuit and this minimum distance depends on the respective operating frequency.
