A multi-protocol RFID interrogating system employs a synchronization technique (step-lock) for a backscatter RFID system that allows simultaneous operation of closely spaced interrogators. The multi-protocol RFID interrogating system can communicate with backscatter transponders having different output protocols and with active transponders including: Title 21 compliant RFID backscatter transponders; IT2000 RFID backscatter transponders that provide an extended mode capability beyond Title 21; EGO™ RFID backscatter transponders, SEGO™ RFID backscatter transponders; ATA, ISO, ANSI AAR compliant RFID backscatter transponders; and IAG compliant active technology transponders. The system implements a step-lock operation, whereby adjacent interrogators are synchronized to ensure that all downlinks operate within the same time frame and all uplinks operate within the same time frame, to eliminate downlink on uplink interference.

A reel receiving device based on RFID is disclosed. A reel receiving device according to one embodiment of the present invention includes a reel receiving antenna array for individually receiving and supporting a plurality of reels each of which is wound by a strip loaded with electronic components by allowing each of the reels to be supported at outer circumferential side in part, and reading independently RFID tags attached to the reels received individually, a switching unit for activating antennas forming the reel receiving antenna array individually in sequence, and a control unit for providing reception-position information of each of the reels by identifying the RFID tag read.

Multiple sensing network units are deployed overhead in a venue, in which RFID tags of interest and RFID product tags are also deployed. Each unit supports an RFID locationing system for reading the product tags in a reading mode of operation with a set of reading parameters, for reading the RFID tags of interest in the venue, for changing at least one of the reading parameters in response to reading an RFID tag of interest that is proximal to a zone of interest, and for reading with emphasis the product tags that are in the zone of interest with the changed reading parameter.

An inventory tracking system to determine the location of an article labeled with an RFID tag in a pocket of a container having a plurality of pockets. The system includes an antenna device that transmits a radiation beam into a pocket to read data from tagged articles. The antenna device includes a first antenna that transmits a beam at the pocket and a second antenna co-located with the first antenna. The second antenna transmits a beam with a predetermined null area oriented to overlap the first antenna's beam at the pocket. In another embodiment, the antenna device includes an antenna that transmits a beam through an antenna gateway device having openings switchable to operable or inoperable states aligned with each pocket. An RFID reader receives the read data from responding tagged articles, and a processor uses the read data to determine whether an article is in a particular pocket.

Systems and methods for location estimation and tracking for passive RFID and wireless sensor networks in accordance with embodiments of the invention are disclosed. In one embodiment, a process for obtaining location information using an RFID reader system includes transmitting a combined interrogation and ranging signal from a plurality of antennas, where the ranging signal is a pseudorandom signal, receiving a backscattered return signal from an RFID tag at one or more receive antennas, extracting an information signal from the return signal and decoding the information signal to obtain RFID tag data, extracting a received ranging signal from the return signal, and estimating a range to the RFID tag based upon correlation between the ranging signal and the received ranging signal.

An antenna device has a radiating unit having a plurality of antennas, configured to emit a radio signal with a radiation pattern. In addition, the antenna device has a calculator configured to generate and to apply to the plurality of antennas a plurality of feed signals based on an identification signal provided in order to generate the radio signal. The calculator is additionally configured to control the feed signals in a time-varying manner so that the radio signal is emitted with a time-varying radiation pattern.

At least some aspects of the present disclosure feature a radio frequency identification (RFID) tag adapted to wirelessly communicate with a remote transceiver. The RFID tag includes a substrate; and first and second circuits disposed on the substrate and comprising respective first and second antennas magnetically coupled to one another. At least some aspects of the present disclosure feature a RFID tag having a plurality of RF circuits, where each RF circuit is electronically coupled to a sensing element.

A reading system comprises a storage section that is provided in a game table and extending in a plane, for storing a game token equipped with an RFID tag; and a reading device having an antenna configured to generate an electromagnetic wave for reading the RFID tag of the game token stored in the storage section, wherein the reading device has a plurality of the antennas corresponding to a plurality of partial areas of the storage section so that the electromagnetic waves of the plurality of antennas do not read the RFID tag of the game token placed in a predetermined area other than the storage section where the game token is placed.

An antenna control apparatus according to an embodiment includes a communication interface configured to receive identification information indicating whether each of a plurality of antennas received transmission information from a wireless tag. A storage unit stores a count for each of the plurality of antennas. A controller determines, for each of the plurality of antennas, whether the antenna received transmission information from a wireless tag based on a first received identification information. When at least one, but not all, of the plurality of antennas is determined to have not received transmission information from a wireless tag based on the first received identification information, the storage unit increments the count for each such antenna. When the count for one of the plurality of antennas is determined to exceed the predetermined value, the controller outputs a notification signal indicating that the one of the plurality of antennas has a malfunction.
