Abstract
Described herein are methods, devices and systems for characterizing an attached antenna to an electronic device, such as a radio frequency identification ('RFID') reader. One exemplary embodiment is related to a method comprising outputting a low amplitude modulation ('AM') index radio frequency (“RF”) waveform, the waveform simulating tag data timing and bandwidth, removing a direct current (“DC”) component from the waveform to create a chopped portion of the waveform, applying at least one vector analyzer technique on the chopped portion of the waveform, characterizing at least one antenna impedance vector of the waveform.
