Abstract:
A reader ( 5 ) with an antenna ( 6 ) that transmits a HF field ( 10 ) with a carrier frequency and receives an analog input signal ( 11 ) with the antenna ( 6 ), which analog input signal ( 11 ) may be load modulated with a modulation frequency, and outputs digital data detected in the input signal ( 11 ), which reader ( 5 ) comprises: a mixer ( 13, 15 ) that mixes the input signal ( 11 ) with a carrier frequency signal ( 9, 16 ) and provides a mixed output signal ( 14 ); target detection means ( 22 ) to detect the presence of a target in the HF field ( 10 ) and to activate processing of the input signal ( 11 ) to communicate with the target, wherein target detection means ( 22 ) comprise: low-pass filter means ( 23, 25 ) to eliminate signal components of the mixed output signal ( 14 ) at the modulation frequency and above and to provide a filtered output signal ( 24 ); quantification means ( 32 ) that quantify the filtered output signal ( 24 ) and provide quantified detection data ( 33 ); decision means ( 36 ) that compare the quantified detection data ( 33 ) with a threshold ( 37 ) to provide a target detected information ( 38 ), while the threshold ( 37 ) is set in-between quantified detection data ( 33 ) received with and without a target present in the HF field ( 10 ).

Claim (Index 8):
Reader according to  claim 1 , wherein the low-pass filter means are built to eliminate signal components of the mixed output signal above a tenth of the modulation frequency and above and to provide the filtered output signal.
