Abstract:
A system, apparatus, and techniques for interrogating a Radio Frequency Identification (RFID) tag are disclosed. The system includes an RFID reader that includes a pivotable 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 out of a null region of the reader. Advantageously, by pivoting the antenna, the antenna apparatus minimizes signal fading and improves signal quality from tags.
