Abstract:
A package for at least two objects includes RFID bridge antennas, having RF antenna elements, for wirelessly communicating data between a tag associated with each object and a reader. An electromagnetic carrier signal transmitted by the reader antenna is received by one of the RF antenna elements and retransmitted to the tag antenna by the other RF antenna element, increasing the distance over which the tag can communicate with the reader. Where the tag is attached to a packaged object, the RFID bridge antenna may be included in the package to allow wireless data communication between the tag and a reader. The reader may also be located external to the package. For example, one of the RF antenna elements may be attached to a label on the package, allowing data stored in the tag to be extracted by the external reader.
