- Title
An Optimization Method of Carrier Suppression for UHF RFID.
- Authors
Liu, Qingshan; Chai, Changchun
- Abstract
The carrier leakage is the key factor that limits the performance of ultra-high frequency radio identification (UHF RFID) reader in high-power transmission mode. The relationship between phase noise suppression and path delay of the carrier leakage is discussed in this work. It is indicated that the suppression degree of the carrier leakage varies periodically with the carrier's transmission path delay. A novel suppression method of the carrier leakage by adjusting antenna feeder's length is proposed. The experimental results are provided to verify the feasibility and correctness of the method.
