摘要： In systems and methods for determining the placement of radio-frequency identification (RFID) tags, a tag reader communicates with one or more RFID tags at different locations of a target object. The tag reader determines which of the different locations is a preferable location for placing an RFID tag by detecting the transmission power level or other value required to communicate with the RFID tag at each of the different locations.

摘要： A compact flexible high gain antenna is disclosed which includes a co-planar array of at least three substantially parallel main conducting antenna elements, a reflector, a driven element, and a director. Each of these elements may be terminated on the ends by a stub element, and the reflector and the director may include an intermediate meander element. Stub elements capacitively load the antenna, while meander elements inductively load the antenna, and the loading affects the resonant frequency of the antenna. The conducting antenna elements may be affixed to a flexible dielectric substrate and may be bent or curved into different compact shapes, suitable for fitting manufacturing form factors for a handheld RFID reader. The antenna has a high directional gain which results in a longer operating range.

摘要： An RFID tag may include an antenna substrate comprising a conductive layer etched or deposited to form an antenna, and a circuit substrate comprising a conductive layer etched or deposited to form a circuit, the antenna electro-magnetically coupled to the circuit. An RFID tag may be formed from an insert substrate comprising an insulative layer between two conductive layers, one of the conductive layers etched to form an antenna and the other conductive layer etched to form a circuit. The insert substrate may be received in an envelope formed by a label substrate, which may carry a pressure sensitive adhesive.
