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.

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： An RF transponder is provided with a miniature resonant antenna that can fit on a small form factor the size of a button or coin. 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： Processes and apparatus for manufacturing radio frequency transponders having substrates formed from a flexible tape or film are disclosed. The RF transponders are formed on the tape so that their longest dimension (e.g., their length ("L")) is oriented parallel to the length of the tape. This layout places few or no constraints in the transponder's length allowing the length of the transponder's antenna circuit to be adjusted to satisfy the requirements of various applications.

摘要： Communication of information between the inside and the outside of an electrically conducting enclosure is performed through the use of a frequency selective surface on the electrically conducting enclosure, which permits passage of electromagnetic waves at particular frequencies, but prohibits waves of other frequencies from penetration. Thus, one or more objects contained within the electrically conducting enclosure, which include radio frequency tags attached to the objects containing information about the objects, may be monitored or interrogated by the transmission of an electromagnetic wave at the permitted frequency through the frequency selective surface. With such a system, control and inventory of enclosed objects may be performed while the EMI shielding function of the electrically conducting enclosure is maintained.
