Abstract

The RFID antenna positioning matrix is formed by uniformly arranging n multiplied by m antenna units of an RFID card reader with the same parameters on the same plane, namely n antenna units of the RFID card reader with the same parameters in a horizontal row and m antenna units of the RFID card reader with the same parameters in a vertical column, and forms an RFID antenna positioning matrix plane. The two ends of each antenna unit are respectively connected with the transverse line and the longitudinal line of the matrix. The horizontal lines of the matrix are connected with the n antenna units, and the vertical lines of the matrix are connected with the m antenna units. When the RFID label is close to a certain antenna unit, the antenna unit senses the electromagnetic wave of the label, and corresponding transverse lines and longitudinal lines output electromagnetic wave signals. The positioning of the label can be realized by combining the matrix processor, the card reader and the display.
