Though I forgot to mention that we're into UHF RFID applications, which means operating frequencies of about 860-960MHz. I've started using Z-parameters. Am I just to conce ...   Topic: passive UHF RFID tags, Backscattering, S and Z parameters daneloctober Replies: 3 Views: 11805 Forum: Questions Related to Antenna Theory   Posted: Sat Oct 01, 2011 9:53 am   Subject: passive UHF RFID tags, Backscattering, S and Z parameters Hello! I was told that it is not very efficient to use S11 parameters to measure the performance of passive RFID tag antennas and to instead use Z11 parameters. Can anyone tell me why this is so?
