摘要： Embodiments described herein provide various designs of multi-frequency radio frequency identification (RFID) tags which are compact in size and tamper-proofing. In one aspect, a proposed multi-frequency RFID tag includes both a high frequency (HF) subsystem and an ultra-high frequency (UHF) subsystem. The HF subsystem and the UHF subsystem share a common integrated circuit (IC) chip and a common substrate. The HF subsystem further includes a HF loop antenna coupled to the IC chip. The UHF subsystem further includes a coupling antenna electrically coupled to the IC chip but electrically isolated from the HF loop antenna. The UHF subsystem also includes an UHF antenna having a region for receiving the RFID module. When the RFID module is positioned within the receiving region of the UHF antenna, the UHF antenna is coupled to the IC chip in the RFID module via the coupling antenna, thereby forming the UHF subsystem.

摘要： The invention relates to a device comprising at least a first RFID module and a second RFID module, each comprising a chip coupled to a wire loop antenna. The first and second RFID modules operate at a first operating frequency into a first frequency band and at a second operating frequency into a second frequency band respectively, the second operating frequency being substantially equal to a multiple k of the first operating frequency, with k≥2. The device further comprises a resonant half-wave dipole having a length (L) that is substantially equal to λ/2 where λ is a wavelength associated to the first frequency band. The first module is present in the vicinity of the center of the half-wave dipole and the second module is present at a distance substantially equal to (2*n+1)λ/4*k from an end of the half-wave dipole, with n∈[0 . . . k−1].

摘要： A wearable article, system, and methods may include a structure configured to enclose a human body part. A first antenna, positioned with respect to the structure, is tuned to communicate, while the wearable article is being worn, according to a first wireless communication modality with a first external antenna. A second antenna, positioned with respect to the structure, is tuned to communicate according to a second wireless communication modality with a second external antenna different than the first external antenna, the second communication modality being different than the first communication modality. A transceiver, coupled to at least one of the first antenna and the second antenna, is configured to communicate via one of the first and second antennas based, at least in part, on the one of the first and second antennas coming into wireless communication contact with a corresponding one of the first and second external antennas.

摘要： A radio frequency identification (RFID) switch tag is disclosed. This RFID switch tag includes a base component having an ultra-high frequency (UHF) booster, and a detachable component having at least one UHF RFID module and a high frequency (HF) RFID module. In some embodiments, the detachable component is positioned in close proximity to the base component in a first configuration of the RFID switch tag such that the at least one UHF RFID module is sufficiently coupled to the UHF booster in the base component to form an UHF RFID system having a desired performance. The detachable component can also be separated from the base component to obtain a second configuration of the RFID switch tag, and the HF RFID module remains functional within the detached detachable component so that the detachable component can be used as a standalone HF RFID tag.
