Claim 0:
1. A barcode reader configured to be supported by a workstation, the barcode reader comprising:
a housing having a window;
a multi-axis radio-frequency identification antenna assembly positioned within the housing of the barcode reader, the antenna assembly comprising:
a first antenna configured to emit a radiation pattern oriented in a first direction;
a second antenna configured to emit a radiation pattern oriented in a second direction, substantially orthogonal to the first direction;
a third antenna configured to emit a radiation pattern oriented in a third direction, substantially orthogonal to the first direction and the second direction; and
a radio-frequency identification radio in communication with the first, second, and third antennas, wherein the radio-frequency identification radio is positioned within the housing of the barcode reader and oriented to act as a reflector for the first, second, and/or third antennas to reflect radio-frequency energy from the first, second, and third antennas towards a product scanning region of the barcode reader,
wherein:
the radiation pattern of the first antenna has a first polarization;
the radiation pattern of the second antenna has a second polarization, different than the first polarization; and
the radiation pattern of the third antenna has a third polarization, different that the first polarization and the second polarization.
