ABSTRACT:
A transponder detector is provided with capabilities for detecting the presence and type of a transponder in its read range while operating at low power. The transponder detector includes an antenna assembly and a detection signal generator circuit coupled to the antenna assembly. The detection signal generator circuit is capable of generating a progression of detection signals on the antenna assembly across a range of frequencies. The transponder detector further includes a response signal receiver circuit coupled to the antenna assembly to receive a progression of response signals from the antenna assembly resulting from the progression of detection signals. A controller is coupled to the response signal receiver circuit which determines the presence and type of the transponder based on an evaluation of a transponder detection parameter in the progression of response signals.
