Abstract
We present wireless impedance measurement for passive UHF RFID tag chips. The measurements are performed on the tag chip when it is connected to the tag antenna in the balanced mode as it operates; neither test fixture nor matching network is needed. The chip impedance measurement in absorbing state and reflecting state by using a time-domain vector reflectometer system. The experimental results are presented for a UHF RFID Gen2 device.
