Experimental demonstration of transmit diversity for passive backscatter RFID systems

Abstract

Passive, backscatter radio frequency identification (RFID) systems are often range limited by the power incident on the radio frequency (RF) tag. We have demonstrated an increase in the power incident on the RF tag using transmit diversity in a monostatic backscatter channel. Transmit diversity was achieved by phase conjugating the forward link of the… (More)
