Hello! We've just gone through the halfway point presentation of our project regarding RFID systems, which involved simulating Passive UHF RFID Tag Antennas in different environments. We used HFSS and the S11 parameter to determine the antenna's performance.
However, we were informed that the S11 parameter is a poor way of determining the the tag antenna performance, since passive rfid tags use backscattering. Can someone enlighten me regarding this matter? If it's true, then how do we best measure tag antenna performance in HFSS Simulations??? We used a lumped port for our signal source, by the way.
