Abstract: A method of using shielded straps with RFID tag designs is disclosed. Specifically, the RFID device, in one embodiment, comprises a bridge conductor which couples the antenna and pair of strap pads together. Thus, the coupling between the bridge conductor and the strap conductor, the coupling between the bridge conductor and the antenna conductor, and the coupling between the antenna conductor and the strap conductor increases the total capacitance of the RFID strap device. Further, the presence of the bridge conductor also reduces the area occupied for a given inductance, and provides a higher effective capacitance when the bridge strap is connected to the antenna.

Abstract: An apparatus and method of combining more than one RFID technology to give operational benefits and new applications to RFID tags is disclosed. The RFID tags comprise UHF and/or HF tag functions which are either located in a single chip or located separately in two chips with a connection between the chips allowing the exchange of information. These RFID tags may then be used in a retail environment to assist in marketing, inventory control, and/or EAS operations.

Abstract: A flexible fabric RFID tag is disclosed wherein a conductor is embedded into a flexible material to form a channel. The channel does not extend through the total depth of the flexible material. The conductor placed in the channel forms an antenna for an RFID tag when coupled to an RFID chip. The channel allows the conductor to be buried into the flexible material to prevent uncomfortable ridges and to create a flat printable surface.

Abstract: A method for manufacturing an antenna for an RFID device includes providing a conductive material on a substrate and performing a first cutting process on the conductive material to define an initial antenna. Additional cutting processes are performed on the initial antenna to define a final antenna, with the first and any subsequent cutting processes being different. The subsequent cutting processes are capable of more finely defining regions of the antenna, such as in some embodiments when the first cutting process is a die cutting process and a second cutting process is a laser cutting process. While the subsequent cutting processes are capable of more finely defining regions of the antenna than the first cutting process. By combining multiple cutting processes, a final antenna equivalent to one made using only one or more of the subsequent cutting processes may be created at a lower cost.

Abstract: A merchandise attachment incorporating an RFID transponder may be described herein. The merchandise attachment may include a pliable, elongated panel member adapted for wrapping around the neck of a bottle or similar container. The panel member may be formed from a unitary blank having score lines that divide the blank into a plurality of panel sections. The panel member, when folded along the score lines with its end sections in overlapping relationship, may form a packaging sleeve in the shape of a tapered rectangular prism. The exterior surface of the panel member may be provided with informational material regarding the merchandise, such as branding, promotional offers, and the like. The RFID transponder, affixed to an interior surface of the panel member, may be adapted for wirelessly communicating information in radio-frequency signals.

Abstract: A temperature-sensing RFID device includes an RFID chip and an antenna electrically coupled thereto. The RFID chip includes a temperature sensor, while the antenna is adapted to receive energy from an RF field and produce a signal. A shielding structure and/or a thermally conductive or absorbent structure may be associated with the RFID chip. The shielding structure is oriented so as to be positioned between at least a portion of the RFID chip and an outside environment and configured to shield the temperature sensor from at least one environmental factor capable of affecting a temperature sensed by the temperature sensor of an article to which the RFID device is secured. The thermally conductive or absorbent structure is oriented so as to be positioned between at least a portion of the RFID chip and the article and configured to enhance thermal coupling between the temperature sensor and the article.

Abstract: Improved RFID devices and manufacturing methods that utilize more efficient RFID designs, result in less manufacturing material waste and increased recycling opportunities, all without sacrificing RFID device performance, are disclosed herein. Some exemplary embodiments of the improved RFID device may make use of a thinner foil, a hollowed-out foil, a "no-strip" design, or a tessellated design that may reduce material usage. Other exemplary embodiments may use a lower-impact and/or biodegradable adhesive so as to improve aluminum recycling and lessen risks to the environment.

Abstract: An active radio frequency identification ("RFID") tag (300) receives an RFID interrogation signal via a first antenna (306). An integrated frequency reference (302) in the RFID chip recovers the clock from the RFID interrogation and generates a reference clock for transmitting data responsive to the RFID interrogation. The integrated frequency reference generates the reference clock at the same frequency as the RFID interrogation for transmitting the response via the first antenna. The integrated frequency reference generates the reference clock at a different frequency for transmitting the response using a Bluetooth beacon message or a WiFi message via a second antenna (314). A mobile computing device (410) can interrogate the RFID tag via an NFC interface and receive a response via a Bluetooth beacon messages or WiFi message received via a Bluetooth or wireless interface of the mobile computing device.

Abstract: A method of increasing conductivity in ink using radio frequency energy. A conductive ink comprising a plurality of conductive particles and a binder is printable on a surface, such as a RF antenna. A RF source is used to apply a RF signal to the conductive ink to decrease electrical resistance in the conductive particles via coherence. Once the conductive particles are sufficiently cohered in a state of lower resistance, the binder is cured to maintain the state of lower electrical resistance and improved conductivity of the conductive ink.
