摘要：A system, apparatus, and techniques for interrogating a Radio FrequencyIdentification (RFID) tag are disclosed. The system includes an RFID reader that includes apivotable polarized antenna for reading a reader/tag link. The antenna moves at a

specific frequency over a specific distance resulting in reader/tag links being moved outof a null region of the reader. Advantageously, by pivoting the antenna, the antennaapparatus minimizes signal fading and improves signal quality from tags.
