摘要： Methods and systems are provided for an RFID system that can be tuned dynamically and/or in real-time during a coupling event between a reader and a transponder. The reader can comprise an antenna assembly, a signal driver, and a controller. The antenna assembly may include a tuning circuit and an antenna coupled to the tuning circuit. The tuning circuit can include registers that may be set to adjust one or more characteristics of the reader. A controller is coupled to the antenna assembly to determine characteristics of the received signal and to set hardware or firmware functions that improve the coupling of the reader and transponder and/or improve the reception of the signal(s) from the transponder.
