摘要： A method and apparatus for identification and monitoring of, and obtaining data relating to, products moving along a distribution path, including at least one RFID tag mountable to a product, or product carrier, and a plurality of interrogators spaced apart along the distribution path, wherein each interrogator of the plurality of interrogators cooperates in RF communication with the RFID tag when the RFID tag is in proximity to the each interrogator along the distribution path. Each interrogator interrogates the RFID tag during the RF communication so as to obtain unique data, unique to the RFID tag. The RFID tag and each interrogator each includes a transceiver and memory, the memory.

摘要： A low loss suspended substrate coupler includes a substrate having a first transmission line disposed on a topside of the substrate and a second transmission line disposed on the bottom side of the substrate, thereby providing broadside transmission line coupling. To provide closer mode velocity matching, the coupler has capacitive loading or coupling to ground at discrete intervals between the two transmission lines. The capacitive loading is formed by integrating stubs in each transmission line at pre-determined intervals, each of which is opposite a corresponding one of a plurality of ground stubs on the other side of the substrate. The ground stubs are connected to ground at the outer edge of the coupler area with substrate vias or directly to the coupler housing.
