Abstract
Provided is a Radio Frequency Identification (RFID) tag having a plurality of antennas. The RFID tag includes: a plurality of antennas each configured to backscatter received Radio Frequency (RF) signals; a digital and memory circuitry, which once the RF signals are received through the plurality of antennas, is configured to generate a series of programmed encoding signals based on identification information to be transmitted, and to output the generated signals; and a modulator configured to vary power of an uplink signal backscattered through the plurality of antennas based on the encoding signals input from the digital and memory circuitry, in which the modulator operates such that the power of the uplink signal backscattered through each of the plurality of antennas is equal regardless of types of the encoding signals.
