摘要： An RFID tag (20) associated with a container (22) having a container wall (24) constructed of a container material (26). The RFID tag (20) includes a microstrip antenna (32) associated with an exterior surface of the wall (24) of the container (22) and a ground plane (30) associated with an interior surface of the wall (24) of the container (22). The container material (26) is interposed between the microstrip antenna (32) and the ground plane (30) and acts as a dielectric substrate. The microstrip antenna (32) may be embedded below, substantially flush with, or affixed to the exterior surface. Similarly, the ground plane (30) may be embedded below, substantially flush with, or affixed to the interior surface. Use of the microstrip antenna (32) reduces or eliminates detuning, while locating the components below or flush with the surfaces of the container (22) protects them from damage.

摘要： The present invention encompasses an antenna (12) for use with a radio-frequency identification transponder (10) that performs optimally in free space and near optimally when near a conductive surface. The radio-frequency identification transponder (10) broadly comprises an antenna (12); an integrated circuit (14); a matching circuit (16) interposed between the antenna (12) and integrated circuit (14); and a substrate (18). The antenna (12) is designed with a length so the antenna (12) as a microstrip resonates at a starting frequency and a matching circuit is constructed. The antenna (12) is placed near a conductive surface and the length of the antenna is adjusted until the antenna reactance is approximately the opposite of the integrated circuit reactance.

摘要： A feed structure (18) and matching circuit (20) for inductively coupling an antenna (16) with an IC (22) in an RFID tag (10). The tag (10) includes first and second feed structures (26,28) coupled with the antenna (16), a first transmission line (30) coupling the feed structures (26,28), and a matching circuit (20) including a second transmission line (32) having a portion that is substantially parallel to and spaced apart from the first transmission line (30) such that the first and second transmission lines (30,32) inductively couple. Where two or more antenna elements (56,57) are used, the elements (56,57) are sufficiently loosely coupled by inductive coupling that they can operate at nearly the same frequency without forming a single resonant antenna. Thus, for example, different elements can operate at approximately 905 MHz and approximately 925 MHz, respectively, to effectively cover the FCC range of 900-930 MHz.
