A ferrite composition, wherein: main components contain, with Fe.sub.2O.sub.3 conversion, 45.0-49.5 mol % of iron oxide, with CuO conversion, 4.0-16.0 mol % of copper oxide, with ZnO conversion, 19.0-25.0 mol % of zinc oxide, a remaining portion is constituted by nickel oxide, an inevitable impurity is removed with respect to the main components, and as accessory components, with TiO.sub.2 conversion, 0.5-2 weight % of titanium oxide, with CoO conversion, 0.35-2 weight % of cobalt oxide are contained.
Systems and methods for providing tags adapted to be incorporated with or in items
Systems and methods for integrating tags with items. The methods comprise: dynamically determining a length of each metal thread to be incorporated into or trace to be disposed on a item to optimize tag performance in view of dielectric and tuning properties of the item. In the metal thread scenarios, the methods also involve: creating a metal thread having the length that was dynamically determined; and sewing the metal thread into the item being produced to form an antenna for a first tag. In the trace scenarios, the methods also involve forming the trace on the item being produced to form an antenna for a first tag. Next, at least a communications enabled device is attached to the item so as to form an electrical coupling or connection between the communications enabled device and the at least one antenna.
RFID tag and method of attaching the same
An RFID tag for stably holding an RFID inlet raised and spaced apart with respect to an article, on which the tag is placed. The RFID tag is raised from a surface of the article by being flexed to bring the RFID tag into contact with a head portion of a banding band. A through hole defined in a tag base allows insertion of the banding band. The hole includes a first through bore and a second through bore. The tag base includes a base region for raising a holding region and a holding region for an RFID inlet for being reused. The base region raises the RFID inlet with respect to the article, and the holding region having the RFID inlet is raised from the base region.
ELECTRICAL CIRCUIT AND METHOD FOR PRODUCING AN ELECTRICAL CIRCUIT
One general aspect of the present disclosure includes an electrical circuit with a circuit carrier, at least one electrical component arranged on the circuit carrier, and at least one data transmission device with an antenna section. The data transmission device may be configured for wireless transmission of data and may include a housing, where the at least one electrical component, the at least one data transmission device, and at least one section of the circuit carrier are at least partially enclosed by the housing. At least the antenna section of the data transmission device may be arranged in a transmission range inside the housing and the transmission range may be spaced at a distance from the circuit carrier.
Antenna device and electronic equipment
An antenna device according to one of embodiments includes: an antenna substrate around which an antenna coil is wound; metallic foil arranged on the antenna substrate to be superposed on a portion of the antenna coil; and a magnetic sheet arranged to be superposed on the antenna coil. On the first side of the antenna coil in which a current flowing is carried in one direction, the antenna coil is closer to the reader/writer than the magnetic sheet is, and/or, on the second side of the antenna coil in which the current flowing is carried in another direction, the magnetic sheet is closer to the reader/writer than the antenna coil is. The metallic foil is superposed on the second side of the antenna coil.
Magnetic marker and magnetic marker system
In a columnar-shaped magnetic marker including a magnet formed by dispersing a magnetic powder of iron oxide in a polymer material and to be laid in a road without being accommodated in a metal container, one end face of an outer peripheral surface and an entire outer peripheral side surface of magnet are covered with metal foil forming a conductive layer, and an RFID tag which performs wireless communication with a tag reader mounted on a vehicle side is arranged on the end face of magnetic marker provided with metal foil as being in a state of being electrically insulated from metal foil.
RFID device with elongated structure
A radio frequency identification (“RFID”) antenna structure such as may be found on a tag, label or inlay for use with consumer products that has a conductive surface. The RFID structure of the present invention can be attached to the conductive surface without significantly modifying the performance of the RFID device. The RFID device has first and second portions, with the first portion having a first antenna pattern and the second portion including an elongate section for attachment to the consumer item.
License plate validation
A license plate validation system for a vehicle is disclosed. This license plate validation system includes: a radio frequency identification (RFID) reader located inside the vehicle and configured to read from an RFID-enabled license plate on the vehicle upon detecting an attempt to start the vehicle; and a microcontroller coupled to the RFID reader and configured to receive, from the RFID reader, information obtained from the RFID-enabled license plate and subsequently determine, based at least on the received information, whether the vehicle is properly registered. In some embodiments, the microcontroller and the RFID reader are integrated as a single electronic module.
RFID enabled metal transaction cards
An RFID enabled metal transaction card comprising (i) a transponder chip module (TCM) having a RF payment chip (IC) and a module antenna (MA), (ii) a coupling frame (CF) in the form of a metal card body (MCB) having an electrical discontinuity comprising a slit (S, S.sub.CF) and (iii) a discontinuous metal frame (DMF) assembled to the metal card body (MCB) in a peripheral area thereof and having a slit (S, S.sub.DMF). The discontinuous metal frame (DMF) is electrically isolated from the metal card body (MCB) and may be coated with an insulating medium. The DMF camouflages the slit in the metal card body and mechanically stabilizes the structure of the card body, especially during insertion in an automatic teller machine (ATM) or point of sale (POS) terminal.
RFIC MODULE AND RFID TAG
An RFIC module is provided that includes a base material having a first face and a second face opposite to each other, an RFIC mounted above the first face of the base material, and RFIC-side terminal electrodes that are formed on the first face of the base material and are connected to the RFIC.
