摘要： A transponder circuit arrangement including antenna contacts to which an antenna signal can be applied. The antenna signal includes at least one signal in one transmission band of a plurality of transmission bands. The transponder circuit arrangement also includes a detector adapted to detect whether the antenna signal includes a signal in a predetermined transmission band, and a demodulator adapted to demodulate the signal in the predetermined transmission band when the signal has been detected therein, and otherwise to demodulate a signal in another transmission band.
