Abstract: A method for using multi-functional RFID tag assemblies, passive repeater systems and modular antenna systems. One embodiment comprises a method for communicating with an RFID tag by providing a passive loop modular antenna system, moving the RFID tag through a field related to the modular antenna system and transmitting energy through the antenna to communicate with the RFID tag. In a further embodiment, the RFID tag includes a passive loop in proximity with the RFID tag to improve the signals received and transmitted by the tag. In another embodiment, the RFID tag is removeably attached to a product container having a product therein and adapted to be removed from the container and re-attached to the product or a second container.

Abstract: A RFID passive repeater system and apparatus comprising a RFID reader having a magnetic flux field, at least one RFID tag and at least one passive repeater member having at least one substantially continuous passive loop, the passive repeater member being adapted and positionable with respect to the RFID reader and the RFID tag to extend the redirect and/or extend the range of the magnetic flux field.

Abstract: A modular radio frequency identification device (RFID) antenna system including a plurality of modular RFID antenna segments that can be connected in multiple configurations to allow multi-directional RF communication with at least one RF tag that passes through the field of the antenna system from different directions and at different orientations and a configuration system to design, order, configure, test and operate the modular RFID antenna system.

Abstract: A high temperature RFID tag is described which has a survival temperature in the range of approximately −40° C. to 300° C. and an operating temperature in the range of approximately −20° C. to 200° C. In one embodiment of the invention, the RFID tag comprises a housing comprising a substantially flexible first thermally resistant material and having a base and a top, and a circuit board substrate comprising a substantially flexible second thermally resistant material which is encapsulated within the housing. In an additional embodiment of the invention, the high temperature RFID tag comprises a substrate assembly, the substrate assembly including a substrate having an integrated circuit disposed thereon, the substrate comprising a substantially flexible first thermally resistant material, and a high temperature encapsulant disposed on a first side of the substrate, the substrate assembly having a survival temperature in the range of −40° C. to 300° C.

Abstract: An RFID antenna system is described comprising an elongated antenna disposed proximate an interrogation path for interrogating transponders moving along the interrogation path. The antenna is oriented such that the longitudinal axis of the antenna is substantially perpendicular to said interrogation path. The antenna provides an active RF interrogation zone that intersects at least 40% of the horizontal longitudinal plane of the interrogation path.
