A measurement method for verifying impedance match condition of assembled RFID tag

摘要

A measurement method for verifying final conjugate match condition of assembled RFID tag is proposed in this paper. The verification results and maximum read range test results are all in good agreement. The verification method can be used to make sure whether the assembled RFID tag is in good match condition or not. In the future work, we will study how to use the verification method to find the resistance and reactance mismatch condition between RFID chip and antenna.
