摘要： Various radio frequency identification (RFID) tags are described that dynamically vary their resonant frequency to reduce or eliminate the potential effects of electromagnetic “tag-to-tag” coupling. An RFID tag, for example, includes a main antenna tuned to a first resonant frequency, and switching circuitry that dynamically changes the resonant frequency of the main antenna. The switching circuitry may selectively couple electrical elements, such as capacitive elements, inductive elements, or combinations thereof, to vary the resonant frequency of the RFID tag. The RFID tag may include a sensing circuit that determines when to selectively couple the electrical element to the main antenna to adjust the resonant frequency of the main antenna.

摘要： A Radio-Frequency Identification (RFID) system verifies proper placement and functionality of RFID tags with respect to particular end-use RFID systems at the time the RFID tag is applied to an item but before the item is deployed. A device for verifying a location and functionality of an RFID tag on an item includes an item holder, a power coupling mechanism attached to the item holder, and an RFID reader electrically connected to the power coupling mechanism. The power coupling mechanism creates a near field for transmission of read or write commands from the RFID reader to an RFID tag on an item placed on the item holder to verify the location and functionality of the RFID tag as applied to the item with respect to a near-field coupling mechanism of a particular end-use RFID system. The device may include additional power coupling mechanisms for testing the functionality of the tag.

摘要： The invention is directed to an extended radio-frequency identification (RFID) tag. The extended RFID tag includes an ultra-high frequency (UHF) RFID tag having a dipole antenna attached to a first surface of a substrate. The extended RFID tag further includes an antenna extension attached to the UHF RFID tag and overlapping at least a portion of the dipole antenna for electromagnetically coupling the antenna extension and the dipole antenna in operation. The extended RFID tag further includes an insulator positioned between the dipole antenna and the antenna extension to electrically isolate the dipole antenna from the antenna extension.

摘要： The invention provides a multi-loop antenna that produces an electromagnetic field having a magnitude of at least an interrogation threshold of a tag for a substantial portion of an interrogation region located in a plane parallel to the antenna. The antenna may include a plurality of loops, including one or more powered loops and one or more parasitic loops. The parasitic loops receive power from mutual coupling with the powered loops causing current to flow within the parasitic loops, which contributes to the profile of the magnetic field. As a result, each parasitic loop may be tuned to provide control over the magnitude of the electromagnetic field. The powered loops and the parasitic loops may be varied over the interrogation period to reduce any area of the interrogation region where the magnitude of the field remains below the interrogation threshold throughout the interrogation period. The powered loops and the parasitic loops may reside on a single layer or may be arranged on multiple layers.
