Abstract
A radio frequency identification (RFID) transceiver is disclosed, the transceiver characterized by: an antenna; a directivity coupler outputting a progressive wave signal inputted from the antenna and a reflection wave signal reflected from the antenna; a VSWR detector using the progressive wave signal and the reflection wave signal to detect a VSWR; a VSWR controller controlling a VSWR characteristic in response to the detected VSWR; and a phase/impedance controller using the controlled VSWR characteristic.
