    摘要： An antenna method and apparatus for a Radio Frequency Identification (RFID) reader includes an RFID reader, a plurality of radio ports of the RFID reader, and a plurality of linearly polarized antenna elements coupled to the radio ports, wherein the RFID reader directs the radio ports to sequentially communicatively connect only one antenna element at a time to the RFID reader such that only one antenna element is operable to transmit/receive at any instant in time. The antenna elements are mounted in an alternating vertically polarized and horizontally polarized configuration.
