MINIATURIZED PLANAR INVERTED FOLDED ANTENNA (PIFA) FOR MOUNTABLE UHF TAGS DESIGN
A folded planar antenna device for radio frequency identification (RFID) reading is provided. The folded planar antenna device includes an RFID chip, a conductor member comprising a binocular-shaped slot; and a substrate. The conductor member is mounted on the substrate and the substrate is connected to the RFID chip through the binocular-shaped slot. The folded planar antenna device can be mounted on different objects, such as metal, meat, or liquid container, without being completely de-tuned.
METHODS OF OPERATION OF AN RFID TAG ASSEMBLY FOR USE IN A TIMED EVENT
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.
ANTENNA DEVICE AND IC CARD HAVING THE SAME
Disclosed herein is an antenna device that includes a magnetic body having a through hole, and a coil pattern including a first winding part and a second winding part overlapping the through hole of the magnetic body. The through hole of the magnetic body includes first and third inner peripheral edges each including a section extending in a first direction and positioned opposite to each other and second and fourth inner peripheral edges each including a section extending in a second direction perpendicular to the first direction and positioned opposite to each other. The second winding part includes an inner peripheral side part wound along the first to fourth inner peripheral edges and an outer peripheral side part positioned outside the inner peripheral side part and wound along the second to fourth inner peripheral edges without being along the first inner peripheral edge.
Multi-purpose RFID label
The disclosure provides RFID labels including a composite label affixed to a surface of a container holding an object, including a first configuration wherein the first label section is positioned in the composite label and wherein the first label section can be removed from the composite label and configured to be affixed to the object.
RFID tag
An RFID tag (1) comprises a substrate (2), an inlay (3), an antenna (4) and an integrated circuit on a chip (5) coupled to the antenna (4). The substrate (2) has a front surface (6), a back surface (7), a first side edge (8) and a second side edge (9). The inlay (3) comprises the antenna (4) and has a fold (10) that is configured to fold over one side edge (8, 9) of the substrate (2) from the front surface (6) to the back surface (7). At least the inlay (3) comprises at least one opening (12).
Analysis of stimulus by RFID
The present invention is directed to an RFID device. The RFID device includes a brace affixed to an inductor or capacitor. The brace is constructed from a material structurally responsive to a predetermined stimulus, such that stimulus-responsive structural alterations to the brace structurally alters the inductor, capacitor, or other RFID subcomponent of the RFID circuit capable of generating a current alteration, which in turn alters the signal frequency of the RFID.
RFID devices with multi-frequency antennae
An RFID device includes a conductive sheet defining at least first and second portions, with an intermediate portion joining the other portions. One or more RFID chips electrically coupled to the portions, such as one or both of the first and second portions of the conductive sheet and to the intermediate portion. The first portion of the conductive sheet defines a multi-turn high frequency antenna having one or more disruptions in the conductive sheet positioned between and/or defining adjacent turns of the multi-turn antenna. The second portion of the conductive sheet defines a first radiating arm of an ultra high frequency antenna. The disruptions direct a high frequency current around the turns of the multi-turn high frequency antenna, while allowing an ultra high frequency current to flow across the disruptions, resulting in the first portion of the conductive sheet defining a second radiating arm of the ultra high frequency antenna.
RADIO FREQUENCY IDENTIFICATION TAG
A radio frequency identification (RFID) tag, includes: a substrate; an antenna formed on a first surface of the substrate; an IC chip electrically coupled to the antenna; an adhesive applied to a first area of the substrate to fix the IC chip and the antenna to each other, and a first laminate layer formed on a second surface of the substrate opposite to the first surface thereof, wherein at least a part of the first laminate layer is missing within a second area, which corresponds to the first area, on the second surface.
WIRELESS IC DEVICE, CLIP-SHAPED RFID TAG, AND ARTICLE HAVING RFID TAG
In a wireless IC device, a columnar body includes a metal body with an insulating film.
