In one embodiment, an RFID reader and active tag (RAT) includes: a first beam forming means for interrogating a plurality of RFID tags using at least a first set of two antennas coupled to a first fixed phase feed network, the beam forming means being configured to adjust gains in the first fixed phase feed network to scan with respect to the plurality of RFID tags; and a second beam forming means for uploading RFID data from the interrogated plurality of RFID tags to an external access point using at least a second set of two antennas coupled to a second fixed phase feed network, the beam forming means being configured to adjust gains in the second fixed phase feed network to direct its RF beam at the external access point.
