<p>In one or more embodiments described herein, there is provided an apparatus configured for use with one or more directional antennas. The one or more directional antennas each have a respective directional axis, a first sensitivity region being proximal to the directional axis and associated with a first variation in sensitivity across the first region, and a second sensitivity region being distal to the directional axis and associated with a second variation in sensitivity across the second region. The second variation in sensitivity is greater than the first variation in sensitivity. The apparatus is configured to discriminate one source of radio frequency identification signalling at a particular angular position from other neighboring sources of radio frequency identification signalling by using the alignment of one or more second sensitivity regions with respect to the particular angular position.</p> |
