Abstract: Radio frequency (RF) reflectors for radio frequency identification (RFID) systems are disclosed. An example RF reflector includes a four-sided housing having an open end, an end, two sides, a top, and an open bottom. The RF reflector is configured to not be electrically coupled to an RFID tag reader. The open end is configured to admit RF signals emitted by the RFID tag reader into the RF reflector, and has a dimension greater than a quarter wavelength of the RF signals. The end, the two sides, and the top include a material that at least partially reflects the RF signals, and the end, the two sides, and the top are electrically connected. Another example RF reflector includes a five-sided housing having two ends, two sides, a top, and an open bottom. One of the ends includes an opening to admit RF signals into the RF reflector.
