Dual function strap for resonating elements and ultra high frequency antennas
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.

Vertically-oriented antenna structure for a timing system
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.
METHOD, SYSTEM, AND APPARATUS FOR RFID LABEL FORMATION AND PLACEMENT
A method, system, and apparatus for forming and applying an RFID label may be shown and described herein. Exemplary embodiments can include a new type of RFID inlay that has a multi-element antenna design, allowing for an RFID label thus equipped to be coupled to a carton, for example, around an edge or a corner. Thus, even if part of the RFID label is blocked or obscured, for example by neighboring cartons, the label can still be read as desired.
Method for producing conducting tracks on a substrate
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.
Overlapping Coil Structures Formed By Folding For Compact RFID Tags
RFID tags are provided with a substrate including opposing first and second surfaces each having first and second portions defined by a fold line therebetween. A conductive trace defines a first coil associated with the first portion of the first surface and a second coil associated with the second portion of the first surface. The first coil has a first number of turns, while the second coil has a second number of turns. An RFID chip is electrically coupled to the conductive trace. The substrate is folded at the fold line so as to bring the first and second portions of the first surface into facing relationship, with at least a portion of the first coil overlapping at least a portion of the second coil. The overlapping coils define an antenna having a number of turns equal to the sum of the number of turns of the two coils.
