Abstract
Systems and methods for compensating for interference in radiofrequency identification (RFID) devices are provided. One system includes an RFID antenna structure having a fixed antenna having a plurality of loops, one or more additional inductive loops and a switching arrangement coupled with the one or more additional inductive loops. The RFID antenna structure further includes a controller configured to control the switching arrangement to selectively switch the one or more additional inductive loops to change an inductance of the fixed antenna.
