READER AND RADIO FREQUENCY IDENTIFICATION SYSTEM HAVING THE SAME, AND METHOD FOR TRANSFERRING A SIGNAL BETWEEN READER AND TAG

摘要

PURPOSE: A reader improving signal transmission performance, a signal transmission method between an RFID(Radio Frequency IDentification) system including the same and a reader and a tag are provided to maximize the signal-noise ratio of the received signal. CONSTITUTION: A reader(10) comprises a plurality of antennas. The reader comprises the signal processing unit and a controller. The signal processing unit processes each response signal received in a plurality of antenna. The controller controls a plurality of antennae based on data processed in the signal processing unit. A tag(20) communicates with the reader. The tag comprises a plurality of antennae.
