Selected ones of the RF resonant circuits are coated with a conductive ink (36) for programming the RF tag. Non-planar RF resonant circuits (40, 50) provide enhanced directivity. The RF resonant circuits (14, 40, 50) are disposed within an elongated body (72, 82, 94) in spaced apart and substantially axially aligned relation to provide elongated RF tag configurations. An RF tag assembly (110) includes attachment mechanisms (116, 118) for attaching an RF tag (128) to a carrier. A dual mode RF tag assembly (140) is also provided which includes a passive RF circuit (144) and an active RF circuit (142).

Each RF tag includes at least one resonant circuit (22, 92, 142, 231, 251) which is resonant at any one of a plurality of different frequencies, a receiver (34, 102, 152,244, 264) for receiving an interrogation signal, and a control (36,104,154,246, 266) responsive to receipt of an interrogation signal for causing its at least one resonant circuit to be resonant at selected ones of the different frequencies in a predetermined time sequence corresponding to a predetermined identification code. The external reader includes a detector (216, 218, 220, 222) for detecting the selected resonant frequencies of the RF tags and a decoder (226) for decoding the time sequence of the selected resonant frequencies for recovering the predetermined identification code.

    摘要: RF tagging system (10) has a plurality of resonant circuits (13) on a tag (12). When the tag (12) enters a detection zone (14), the system determines the resonant frequency of each of the resonant circuits (13) and produces a corresponding code. Preferably, resonant frequency detection is implemented by simultaneously radiating signals at each possible resonant frequencies for the tag circuits (13). The system is useful for coding any articles such as baggage or production inventory. Preferably, the radiated signals are phase shifted during the detection process, and signals received by receiver antennas, besides transmitter signals, may be monitored to improve the reliability of detecting the resonant circuits (13). Also, a preferred step adjustment configuration for capacitive metalizations (106, 110) of the resonant circuits is described. For radiating signals into the detection zone (14), focused beam antennas (201) may be used such that each resonant circuit location on the tag can be separately monitored. Also, an apparatus (300) for producing customized resonant circuit tags in accordance with a specified input code is described.

    摘要: A unitary flexible substrate has three planar areas with components and conductors carried thereon. The substrate is folded to provide a subassembly with a compact packaging factor such that each planar area is in a different parallel plane. Two conductor-carrying projections of the substrate extend from different end portions of the substrate to free distal ends of the projections which are positioned adjacent to each other. The projection conductors, at the projection distal ends, are soldered to each other to provide a more direct, low resistance electrical connection between conductors on the substrate end portions. Heat sink rigidizer plates are attached to each of the three planar substrate portions. One rigidizer plate is thermally and planarly coupled to a metal heat sink cover of a protective housing for the folded subassembly. The other rigidizer plates are planarly bonded to each other to form a unitary support structure for two of the planar substrate portions.
