Patent ID: 7930010

Claim:
An automatic antenna identification system, comprising: a connector to which a plurality of different antennas tuned to different respective frequencies or frequency bands may be connected; and circuitry that automatically identifies which antenna of the plurality of different antennas is connected to the connector based on the respective frequency or frequency band of the antenna; a plurality of different RF circuits, each having its own respective output for outputting a signal within a corresponding operation specific frequency or frequency band; and an RF generator for generating excitation signals at predefined frequencies corresponding to the operational frequencies or frequency bands of the plurality of different RF circuits; the circuit comprising: a multiplexer having a plurality of inputs coupled to the corresponding outputs of the plurality of RF circuits; and a controller coupled to the multiplexer and causing the multiplexer to selectively couple the output of the RF generator to the antenna to provide the excitation signal based upon which the circuitry determines which antenna from of the plurality of different antennas is connected to the connector; wherein the multiplexer automatically connects the antenna identified as being connected to the connector to a selected input and/or output of an RF circuit from among the plurality of different RF circuits, the multiplexer selecting the input and/or output of the RF circuit based on the identification of the antenna.
