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.

Abstract: The disclosure is a scanning device comprising a scanning assembly including a scanning engine and a scan window; a bezel including a first opening, a second opening, and a bezel body extending between the first and second openings and having an inner surface and outer surface; an antenna assembly including a transceiver and at least one antenna element; and a housing including a handle portion, a head portion, and a trigger portion. The scanning engine is coupled to the scan window and the scan window at least partially covers the first opening. The antenna element is arranged around at least a portion of a surface of the bezel body. The head portion is configured to include the bezel, at least a portion of the antenna assembly, and at least a portion of the scanning assembly, and the trigger portion which couples to the scanning engine.

Abstract: A barcode reader configured to be supported by a workstation and having a housing with a window. A multi-axis radio-frequency identification antenna assembly is positioned within the housing of the barcode reader and includes first, second, and third antennas. The first antenna is configured to emit a radiation pattern oriented in a first direction, the second antenna is configured to emit a radiation pattern oriented in a second direction, substantially orthogonal to the first direction, and the third antenna is configured to emit a radiation pattern oriented in a third direction, substantially orthogonal to the first direction and the second direction.

Abstract: A bioptic barcode reader configured to be supported by a workstation and having a lower housing with a platter having a generally horizontal window and a tower extending generally perpendicular to the lower housing and having a generally vertical window. A radio-frequency identification radio is positioned within the lower housing and is communicatively coupled to a feed patch positioned within the lower housing and proximate, but spaced apart from, the platter such that the feed patch is capacitively coupled to the platter and configured to energize the platter such that the platter is operative as a radio-frequency identification reader antenna.

Abstract: A RFID-integrated indicia reading device and methods with increased read range via mode detection is provided. The device comprises an imaging assembly configured to capture two-dimensional image data appearing in a first field of view; an antenna assembly including at least one antenna element, being arranged proximate to the imaging assembly within a housing; and, a controller, coupled to the imaging and antenna assemblies, configured to determine a presentation operating mode of the device and a handheld operating mode of the device. The presentation operating mode is indicative of the device being positioned in a cradle, and the handheld operating mode is indicative of the device being held by and positioned in front of a user. The controller, in response to determining the device is in handheld operating mode, increases a transmit power of the antenna element, which generates backward energy that reflects from the user and increases a forward read range of the device.
