Abstract: The invention relates to a transponder layer (30), in particular for producing a laminate structure, for example being embodied as a chip card, having an antenna substrate (31), which, on an antenna side (38), is equipped with an antenna (33) formed from a wire conductor (32) as well as with a chip (41), and which, on the antenna side, has terminal conductors for connecting the chip to the wire conductor of the antenna, in such a manner that the chip is arranged adjacently to terminal ends (34, 35) of the wire conductor, and in such a manner that both the terminal ends of the wire conductor and chip terminals (39, 40), which are arranged on a contact side of a semiconductor body of the chip, said contact side facing towards the antenna substrate, are contacted with the terminal conductors.

Abstract: A decoding device includes a signal-conditioning device for generating an intermediate signal from an input signal, a data register for storing a time section of the intermediate signal and a bit decoder for converting the intermediate signal into an output signal having at least one bit. The decoding device also includes a pattern recognition device. The decoding device enables even severely disturbed signals to be reliably detected and correctly decoded. Simple adaptation of the decoding device to various uses is possible. A smart card including the decoding device is also provided.

Abstract: A device for a contactless transmission of data includes a data transceiver with an antenna. The impedance of the antenna of the data transceiver is purposely mismatched. A reactance is introduced into the antenna in order to tune the antenna to a frequency different from its resonant frequency. In the event that the antenna impedance has to be adapted to the characteristic impedance of a line of unknown length, the loss resistance of the antenna is deliberately increased. The power required to produce a magnetic alternating field with the data transceiver for operating at least one portable data carrier is reduced.
