Method of producing wire inlaid on a support and inlaid wire obtained. The invention relates to an antenna for radiofrequency transponder, said antenna comprising conducting wire portions which are to a major extent inlaid and conducting wire portions which are to a minor extent non-inlaid on a plane support. The antenna is characterized in that said wire portions which are to a minor extent non-inlaid extend over or cross at least one favoured fold line and/or one fold line predefined according to a standardized folding resistance test. The invention also relates to a portable electronic object comprising said antenna and a corresponding method of production.

A method of operating a radio frequency identification (RFID) tag assembly in a timed event including in the radio frequency identification (RFID) tag assembly having a spacer having a thickness of between about 0.125 inches and about 0.5 inches, placing the RFID tag assembly in a position relative to the operating surface of the body a minimum spaced apart distance, receiving at the first side of the two sided planar antenna a first portion of the radio frequency energy as direct energy as transmitted from the antenna of the base station transceiver, receiving at the second side of the two-sided planar antenna a second portion of the radio frequency energy as indirect energy as transmitted from the base station transceiver antenna, the second portion of the radio frequency energy being received at the predetermined operating frequency, and processing the received first and second portions of the radio frequency energy.

An RFID unit includes an RFID unit A and an RFID unit B that are separable on a break line, where the RFID unit A includes an IC chip portion A that stores an UUID and an antenna portion A, and the RFID unit B includes an IC chip portion B that stores an UUID and an antenna portion B. Before the RFID unit is separated into the RFID unit A and RFID unit B, either the RFID unit A or RFID Unit B transmits a first signal including the UUID. After the separation, at least either the RFID unit A or RFID unit B transmits a second signal, different from the first signal, including the UUID.

The invention concerns a patch RFID device (1A, 1B, 2, 3) for tires, designed to be applied to an inner liner of a tire before or after tire vulcanization/curing and comprising an innovative flexible multilayer planar structure.

Wearable ring using near field communications (NFC) to store, receive, and transmit information. A ring can be made from silver or gold materials, the ring band having a first unfinished section with a recess for retaining an NFC chip and antenna and a cut or broken section creating a thin vertical line inside the ring from which a signal can escape. The antenna is a copper wire wrapped around the ring, in the recess of the unfinished band, before being covered with a second layer of metal having a non-metallic section covering the cut or broken section allowing the NFC signal to escape from the inner confines/recess of the ring. The antenna is turned around the ring and soldered to a near field communications (NFC) chip. The ring uses the power from the NFC chip, which communicates via magnetic induction providing a reading distance up to 5 cm.

Embodiments disclosed herein show an NFC ring having a flat-bar FPC and a processing flow thereof, and more particularly to an NFC ring and a processing flow thereof, wherein by providing a flat-bar FPC, the signal transmission and reception effect as well as the anti-interference efficiency can be improved, along with that the processing flow can be simplified to improve the production efficiency and the yield of the product. In addition, the NFC ring can be made more miniaturized, and the data in the NFC ring can be prevented from being stolen by the unique induction method thereof.

A portable free-standing vertical RF antenna structure for use in an UHF timing system comprises a base structure for supporting the vertical antenna structure on a substantially horizontal surface. At least a first antenna unit comprising a first planar RF antenna and at least a second antenna unit comprising a second planar RF antenna, the second antenna unit being located above the first antenna unit, are coupled to the base structure and form a vertical RF antenna structure. The first and second antenna unit is positioned such that the inclination angle between a main axis of the radiation field of the first RF antenna and the horizontal surface is selected between 10 and 50 degrees. The inclination angle between a main axis of the radiation field of the second RF antenna and the horizontal surface is selected between 20 and 20 degrees.

A combined EAS and RFID circuit includes an HF coil antenna, a UHF tuning loop, and an RFID chip coupled to a strap that includes a first coupling area and a second coupling area. The coil ends of the HF coil antenna are configured to capacitively and/or conductively couple to one or both of the first coupling area or second coupling area of the strap. The HF coil antenna can include a gap between turns for non-interfering placement of the UHF tuning loop. The EAS circuit can be deactivating upon application of a field at the resonant frequency of sufficient intensity to cause the breakdown voltage to be exceeded between a coil end and coupling area. The threshold breakdown voltage between a coil end and a coupling area can be reduced by laser ablation treatment of a conductive surface of one or both of the coil end or coupling area.

In a wireless IC device, a columnar body includes a metal body with an insulating film. A loop-shaped antenna conductor is provided on an upper surface of the columnar body via an insulating pedestal. The loop surface of the antenna conductor is parallel or substantially parallel to the upper surface of the columnar body. On the lower surface of a RFIC element, two terminal electrodes are provided. The RFIC element is mounted on the antenna conductor such that the two terminal electrodes are connected to both ends of the antenna conductor, respectively. One end of the connecting conductor is connected to the vicinity of one end of the antenna conductor, and the other end of the connecting conductor is connected to the upper surface of the columnar body.
