摘要： A circularly polarized antenna includes a generally helical wire defining a generally cylindrical passage having a first end and a second end. A first ground plane is proximate the first end of the generally cylindrical passage and has a width substantially equal to a diameter of the generally cylindrical passage. A cable extends through the generally cylindrical passage and is electrically coupled to the first ground plane and to the generally helical wire proximate the first end.

摘要： A radio frequency identification (RFID) tag is adapted to operate with a wideband or multiple band of frequencies, such as 860-960 MHz. The RFID tag includes a flexible antenna inlay structure that can be integrated into a rigid structure to form a rigid RFID tag. The antenna inlay structure can be folded to provide a compact rigid RFID tag. The antenna inlay structure may also be used in a smart label. The antenna inlay structure can work with RFID chips operating under Gen 2, ISO, or other protocol. The RFID tag can be provided with a metallized label that operates to shield the antenna inlay structure against electromagnetic effects of an object (such as a metallic object) having the RFID tag affixed thereon.

摘要： Field Configurable Radiation Antenna Device for fixed dipole antenna comprising of a hollow tube and at least one pair of directional vanes is described. The beam direction of the antenna can be changed by operationally connecting multiples pairs of directional vanes to the hollow tube and by rotating the directional vanes relatively outer peripheral surface of the hollow tube. Such adjustments allow the user to tune the antenna to meet new or unforeseen coverage issues.

摘要： A radio frequency identification system comprises a radio-frequency identification substrate and an interrogator. In one embodiment, the radio-frequency identification substrate comprises a plurality of radio-frequency identification devices. In one embodiment, a controller on the substrate controls a first one of the plurality of radio-frequency identification devices based on a state of a second one of the plurality of radio-frequency identification devices. In one embodiment, an antenna system includes an S-shaped portion electrically coupled to an integrated circuit along a central portion of the S-shaped portion. Adjusting the parameters of the segments making up the S-shaped portion controls performance characteristics of a radio-frequency identification device.

摘要： A radio frequency identification (RFID) reader outputs an interrogation signal, and hops/varies the phase of the interrogation signal sent by the RFID reader over time. Varying the phase of the interrogation signal enables the RFID reader to provide, for each zone of an RF field of the RFID reader, a particular phase that reduces of the effects of interference RF signal(s) present in that zone of the RF field. Reducing the interference in each zone of the RF field increases the throughput of RFID tags that can be successfully read by the RFID reader.
