Abstract
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.
