摘要： An improved radio frequency transponder has a reflector to increase its operative range. A system of one or more reflectors is operatively associated with a transponder and may be formed out of any sort of radio frequency reflective material. The reflector system can enhance reception or transmission of radio waves by or from the transponder. The reflector system may also be used to provide for selective coupling of the radio frequency transponder with a base station, user- or vehicle-supported reader, or the like based on relative orientation. In addition, the reflector system may be used to selectively reflect particular radio waves.

摘要： A radio frequency identification (RFID) transponder (tag) includes a spiral over ground plane antenna. The RFID tag includes a RFID circuitry that may be implemented as an RFID tag integrated circuit and may be mounted on one surface of a substrate such as a printed circuit board. The RFID tag circuitry may be electrically connected to an impedance matching circuit printed on the same side of printed circuit board. The matching circuit is electrically connected to a spiral antenna that may be mounted on same side of the printed circuit board as the tag circuit and matching circuit. The spiral antenna is held a prescribed distance from the ground plane in order to maximize the gain of the RFID tag and to thereby maximize the range of the RFID tag.

More particularly, the RF transponder comprises a substrate and an RF integrated circuit disposed thereon. An antenna is provided on the substrate and is electrically connected to the RF integrated circuit. The antenna has a contorted shape that permits it to fit into the limited available space on the substrate, while having an electrical length that is greater than a maximum length dimension of the substrate. Possible shapes for the antenna may include a meander antenna, a non-uniform meander antenna, a bent dipole antenna, a spiral antenna, a z-shaped dipole, a squeezed dipole antenna, or a combination of any of the antenna types. The RF transponder may further include at least one loading bar spaced from the antenna and/or at least one tuning stub coupled to the antenna.

摘要： The present invention is directed to an ultra-thin outline package for integrated circuits that is much smaller than conventional chip packaging structures. The ultra-thin outline package is particularly useful in fabricating RF or RFID transponders. In an embodiment of the invention, the ultra-thin outline package includes a substrate having an aperture. At least one conductive trace that includes upper and lower portions is disposed on respective upper and lower surfaces of the substrate. The substrate further comprises at least one via electrically connecting the conductive trace portions together. An integrated circuit is disposed in the aperture and is operatively coupled to the upper portion of the conductive trace. An encapsulant is provided in the aperture substantially covering the integrated circuit. The lower portion of the conductive trace is adapted for coupling of the ultra-thin outline package to a secondary substrate using conventional surface mounting techniques. The via connecting the upper and lower trace portions may be disposed either on at least one edge surface of the aperture or on at least one edge surface of the substrate. At least one wire bond electrically couples the integrated circuit to the conductive trace, and the encapsulant covers the integrated circuit and the wire bond. Using printed circuit board material for the substrate, the ultra-thin outline package achieves a vertical profile of approximately 0.3 to 0.375 mm (12 to 15 mils).
