  • RADIO FREQUENCY IDENTIFICATION (RFID) METHOD AND APPARATUS FOR MAXIMIZING RECEIVE CHANNEL SIGNAL-TO-NOISE RATIO BY ADJUSTING PHASE TO MINIMIZE NOISE
    Publication number: 20090179740
    Abstract: Noise in a receive path of a radio frequency identification (RFID) reader is reduced by using a phase shifter. By reducing the noise, the signal-to-noise ratio (SNR) in the receive path of the RFID reader is improved, thereby increasing the number of RFID tags that can be read in a noisy environment over time and/or improving the capability to distinguish a return signal of the RFID tag(s) from noise. The phase shifter adds a phase shift to a reflected signal and a leakage signal, or to a local oscillation signal.
