Said system includes: - at least one RFID transponder (300); - at least one RFID device referred to as a "repeater" (200); and - at least one RFID terminal (100). The at least one RFID terminal (100) is configured to transmit a query signal to the at least one repeater (200) at a frequency F1. The at least one repeater (200) is configured to repeat said query signal at a frequency F1 to the at least one RFID transponder (300) at a frequency F2, and the at least one RFID transponder (300) is configured to transmit a backscattered response signal at a frequency F3. The system is characterized in that the at least one repeater (200) is configured to carry out an analog-only frequency transposition from Frequency F1 to Frequency F2.

摘要： The present invention relates to a RFID communication system comprising an interrogator (10) including a signal generator (12) for generating an interrogation signal at a predetermined frequency f
0 and a first interrogator antenna (11) for transmitting said interrogation signal and receiving a first reply signal at a frequency f
0 , and processing means (13), and a passive transponder (20) including a first transponder antenna (21) for receiving said interrogation signal and a chip (22) comprising nonlinear components for generating said first reply signal in response to the interrogation signal, said first reply signal being transmitted by said first transponder antenna. According to the invention, the interrogator is arranged to receive a second reply signal whose frequency is a multiple of the predetermined frequency f
0 , 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.

摘要： The present invention relates to a circularly polarized directional helical antenna that is capable of being used in RFID devices and more particularly in RFID readers. The antenna is intended to transmit or receive signals in a predetermined frequency band, λ being the wavelength associated with the minimum frequency of the predetermined frequency band. It includes a helicoidal radiating element made of conductive material extending along a longitudinal axis (A) and the axial length (H) of which is less than the wavelength λ, and a cavity made of conductive material having an open end and a closed end and having an axis of symmetry that coincides with the longitudinal axis of the radiating element, at least one lower portion of the radiating element being arranged inside the cavity so that its lower end is in contact with the closed end of the cavity.

摘要： The invention relates to a device which is used to identify articles (4) comprising an RF-ID-type contactless label, said articles (4) being aligned on a medium. The inventive device comprises an antenna (3). The invention is characterised in that the aforementioned antenna (3) is disposed in a flexible head which can deform upon contact with the contour of at least some of the aligned articles (4), in order to form a contact zone with the contour of the articles (4) which are in contact and a zone extending a handling support. The invention also relates to a system for identifying articles (4).

摘要： The present invention relates to a RFID reader with an antenna system for emitting and receiving RFID signals. The antenna system includes at least a first inverted F antenna and a second inverted F antenna each having a feed element, a radiating element with a first end coupled to the feed element and a second end free, and a tuning element having a first end coupled to the ground plane and a second end coupled to the first end of the radiating element. The radiating elements of the two inverted F antenna extend in a first direction and a second direction respectively, said first and second directions being offset by a non-zero sequential rotation. In addition, the two inverted F antennas are isolated from each other by a quarter wavelength slot etched in the ground plane between the two antennas.
