Antenna for wireless tag

An RFID device. The device comprises a conductive layer formed on a first substrate. An opening line (or two or more opening lines) is formed in the conductive layer to make the conductive layer a part of an antenna structure. An integrated circuit chip is placed over at least a portion the opening line and coupled to the conductive layer. The integrated circuit chip is electrically interconnected to the conductive layer.

Radio frequency identification (RFID) tag for an item having a conductive layer included or attached

An identification system includes a reader and one or more tags. The reader identifies tags such as radio frequency (RF) tags. The system divides a number space into n bins, wherein each bin is associated with m unique bits of the number space, and the number space contains the identification codes of the tags. A command is issued to test v bits of the number space. A response is received from a tag, wherein the response occurs when a first portion of an identification code of the tag matches the v bits of the number space, a timing of the response corresponds to a particular bin and m unique bits associated with the particular bin correspond to a second portion of the identification code.

Methods and apparatus for anti-collision for radio frequency communication

A Radio Frequency Identification (RFID) device. The RFID device comprises an antenna assembly and a resonator assembly. The antenna assembly comprises a first substrate and an antenna element. The resonator assembly comprises a second substrate having an integrated circuit connected to a resonator loop. The first substrate and the second substrate are attached to one another. The integrated circuit electrically couples to the antenna element without a direct mechanical contact.

An RFID device. The device comprises a conductive layer formed on a first substrate. An opening line (or two or more opening lines) is formed in the conductive layer to make the conductive layer a part of an antenna structure. An integrated circuit chip is placed over at least a portion the opening line and coupled to the conductive layer. The integrated circuit chip is electrically connected to the conductive layer.

An electronic assembly with integrated circuit capacitively coupled to antenna. The electronic assembly includes a strap assembly and an antenna assembly. The antenna assembly includes a first substrate and antenna elements. The strap assembly includes a second substrate and an integrated circuit embedded within the second substrate and substantially flush with a surface of the second substrate. Interconnections are formed to the integrated circuit. The interconnections are formed on the surface of the second substrate. The antenna assembly and the strap assembly are affixed to one another with the surface of the second substrate facing the antenna elements. The antenna elements capacitively couples to the integrated circuit through the interconnections with no direct contact. A non-conductive layer is disposed between the antenna elements and the interconnections providing the capacitive coupling.

RFID strap capacitively coupled and method of making same

An electronic device. The device comprises a metalization layer and an integrated circuit chip incorporated into the device wherein the integrated circuit chip is capacitively coupled to the metalization layer. The device comprises a first substrate having the metalization layer formed on the substrate, a cap layer covering at least the entire metalization layer and at least a portion of the first substrate not covered by the metalization layer. The integrated circuit chip is coupled to the first substrate, and is placed in proximity and in non-physical contact with the metalization layer. A conductive layer is attached to the integrated circuit chip. The conductive layer has at least a portion placed in a non-physical contact with the metalization layer. The integrated circuit chip is capacitively coupled to the metalization layer through the conductive layer and the metalization layer.

Transponder incorporated into an electronic device

An identification system includes a reader and one or more tags. The reader identifies tags such as radio frequency (RF) tags. The system divides a number space into n bins, wherein each bin is associated with m unique bits of the number space, and the number space contains the identification codes of the tags. A command is issued to test v bits of the number space. A response is received from a tag, wherein the response occurs when a first portion of an identification code of the tag matches the v bits of the number space. A timing of the response corresponds to a particular bin and m unique bits associated with the particular bin correspond to a second portion of the identification code.

Methods and apparatuses for identification

A system and method for acquisition management of subject position information that utilizes radio frequency identification (RF ID) to store position information in position tags. Tag programmers receive position information from external positioning systems, such as the Global Positioning System (GPS), from manual inputs, such as keypads, or other tag programmers. The tag programmers program each position tag with the received position information. Both the tag programmers and the position tags can be portable or fixed. Implementations include portable tag programmers and fixed position tags for subject position guidance, and portable tag programmers for collection sample labeling. Other implementations include fixed tag programmers and portable position tags for subject route recordation. Position tags can contain other associated information such as destination address of an affixed subject for subject routing.

System and method for acquisition management of subject position information

According to an embodiment of the invention, a patch antenna includes a patch coupled to a ground plane. The ground plane includes a first and second strip line. When the first strip line is activated, the antenna generates a signal having a first polarization, and when the second strip line is activated, the antenna generates a second polarization. The first polarization may be a horizontal polarization, and the second polarization may be a vertical polarization. The antenna may be incorporated into a radio frequency identification (RFID) interrogator, which may be used to read RFID tags attached to individual items.
