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： A method and system of determining spatial identification of an object, such as orientation, size, location, range, and/or movement, using an RFID system is disclosed. An RFID system can comprise one or more RFID reader receiving antennas that query one or more RFID tags coupled to the object. The measurement of the phase of the tag responses at the reader antennas and phase differentials as a function of distance, frequency, and time are the basis of spatial identification. The system can work with conventional Gen 2 tags and readers without modification of the tags or protocol.

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： Data carriers (such as RFID tags) are formed into clusters of data carriers. Each cluster has at least one bridge data carrier that can communicate with a bridge data carrier of another cluster, thereby allowing data carriers in each cluster to communicate directly or indirectly with each other using a stochastic communication protocol method. Direct tag-to-tag communication capability is provided between data carriers in each cluster and/or between clusters. The data carriers can backscatter and modulate a carrier wave from a source, thereby using the backscattered and modulated carrier wave to convey data to each other.
