APPARATUS AND METHOD OF OPTIMIZING OUTPUT POWER OF RFID READER

摘要

Provided are an apparatus and method of optimizing a power output of a radio frequency identification reader (RFID) reader. The apparatus includes a loss measurement unit which measures an interface loss between the RFID reader and an antenna by receiving a signal output from the antenna of the RFID reader, a output power compensation amplifier which amplifies a power output to compensate for the measured interface loss, and an output fixation unit which uniformly maintains a power output of the output power compensation amplifier by storing the output compensated power value.
