RFID READER ANTENNA ARRAY STRUCTURE AND RFID READER

摘要

Disclosed in the present invention is an RFID reader antenna array structure, the RFID reader antenna array structure comprising a base plate and multiple antenna array elements which together form an antenna array, wherein the base plate is connected to each of the antenna array elements by at least one grounding short circuit device, and a feeding device is further connected between each of the antenna array elements and the base plate. By way of the technical solution of the present invention, the antenna array structure can obtain a higher far-field gain while achieving a reduction in size in comparison with traditional antenna structures, realizing a beam scanning function of the RFID reader antenna, increasing reading distance and reducing the probability of reading gaps.
