摘要： A portable/handheld device is provided having a processing module configured to selectively operate a reading mode selected from a far-field mode and a near-field mode, and a directional antenna array coupled to the processing module. The directional antenna array includes a first antenna element configured to radiate electromagnetic (EM) radiation in a far-field, and a second antenna element coupled to the first antenna element. The second antenna element is configured to radiate EM radiation in a near-field. The second antenna element includes an antenna transducer configured to selectively cancel far-field EM radiation from the first antenna element. A method of reading inductively coupled radio frequency identification (RFID) tags is also provided having the steps of scanning at least one frequency band to detect a RFID tag, and selectively radiating one of a near-field electromagnetic (EM) field and a far-field EM field based on the detected RFID tag.

摘要： Methods and apparatus are provided for locating one among many items equipped with RFID tags. The apparatus comprises a portable system interrogating the RFID tags and receiving responses therefrom that depend at least on their bearing angle. A comparator selects responses from the one item and ignores others. An annunciator indicates the presence of the one item in the interrogator field of view and, desirably but not essentially, its relative proximity. A directional antenna whose beam pattern is limited in azimuth and/or elevation provides bearing angle information. Its field of view becomes progressively smaller as the antenna approaches the one item so that a user can substantially pinpoint its location without needing any of the usual RFID infrastructure. Tag response hit rate and/or signal strength provides range related information to the interrogator. Optionally, the presence of each new tag is announced until all new tags have been identified.

摘要： Containers for holding goods are provided with a relay conductive structure for relaying RFID tags signals from one side of the container to another. The conductive structure includes a first antenna on the first side of the container, a second antenna on a second side of the container and a transmission line connecting the antennas. When the containers are arranged in a stack, the relay of RFID signals past each row of containers enables the interrogation toward the rear of the stack without disassembling the stack of containers.

摘要： Described are RF tracking system and method. The RF system may include a shell for holding a plurality of containers which store a material that interferes with RF communications. The shell includes a bottom container supporting surface and a plurality of leg extensions attached thereto; the shell extends away from the bottom surface. The tracking system also includes at least one RF tag attached to a first one of the leg extensions. The tag has a memory arrangement storing data relating to at least one of an identity of the shell, an identity of the containers held in the shell and a material stored in the containers. Furthermore, the tracking system includes at least one RF scanner communicating with the tag to collect the data and a computing arrangement which includes a database and communicating with the scanner to update the database as a function of the collected data. The tag is situated at a predetermined distance away from the containers held in the shell to overcome an electromagnetic dampening effect of the material.
