Abstract: A radiofrequency transmission/reception device includes a first and a second conductive wire element, a first far-field transmission/reception chip and a second near-field transmission/reception chip. The first and the second wire element combine with the characteristic impedance of the second transmission/reception chip in order to form a coupling device associated with the first transmission/reception chip at the operating frequency of the first chip. The first and the second wire element combine with the characteristic impedance of the first transmission/reception chip in order to form a coupling device associated with the second transmission/reception chip at the operating frequency of the second chip.

Abstract: A method for joining a microelectronic chip to at least one wire element comprises a first step of applying a cover to a first face of the microelectronic chip, the cover being configured to form, with the first face, at least one temporary side groove. The method additionally comprises a step of inserting the wire element into the temporary groove. The method further comprises a step of attaching the wire element to the microelectronic chip. The method additionally comprises a step of removing the cover from the microelectronic chip.

Abstract: An RFID communication system comprises an interrogator including a signal generator for generating an interrogation signal at a predetermined frequency f0 and a first interrogator antenna for transmitting said interrogation signal and receiving a first reply signal at a frequency f0, and processing means, and a passive transponder including a first transponder antenna for transmitting said first rely signal and receiving said interrogation signal and a chip comprising nonlinear components for generating said first reply signal in response to the interrogation signal. The interrogator is arranged to receive a second reply signal whose frequency is a multiple of the predetermined frequency f0, said multiple being either odd or even, said second reply frequency being generated by the nonlinear components of the transponder chip, said first and second reply signals being processed by the processing means of the interrogator in order to complete or improve the functionality of the system.
