Abstract: A RFID tag or label comprises a RFID tag module (comprising an electronic identification circuit and a coupling means) and an antenna structure coupled to the coupling means. The RFID tag module is separate from, separable or arranged to be severable from, the antenna structure. The tag module can be placed in or on an object and the antenna structure in or on packaging material for use with the object. A patch antenna type RFID tag antenna structure has a ground plane spaced from the patch antenna so as to increase the range of the tag. The ground plane is not substantially larger than, and electrically insulated from, the patch antenna. The ground plane is flexible, so the RFID tag structure can be worn by a human, and can be incorporated into a piece of clothing. A RFID antenna structure for use with a tag reader is made flat and robust so that it can be mounted on the ground to be walked upon or driven over. A bi-directional YAGI type RFID tag antenna structure has director elements on two opposite sides so that the YAGI antenna radiates in two opposite directions. An object includes a gain increasing metallic structure for increasing the gain of a RFID tag when placed near the object so as to form a RFID tag antenna structure.

Abstract: A method of identifying a plurality of transponders, the method comprising receiving at an interrogator one or more data transmission blocks from each transponder, wherein the first data block contains a uniquely detectable transponder identity and zero or more further data blocks defining a set of data blocks making up a transponder transmission. The first data transmission block also contains in transmission block number; one or more further data transmission blocks containing additional block data and a respective transmission block number; the block number being changed, by decrement or increment, automatically as each data block is transmitted.
