发明名称 Communication device with a coil configuration for the communication with stationary data carriers
摘要 In a communication device ( 1 ) with firstly a coil configuration ( 2 ) which has two oppositely situated sub-configurations ( 3, 4 ), by means of which a communication field operative between the two sub-configurations ( 3, 4 ) can be generated and each of the two sub-configurations ( 3, 4 ) having at least two coils ( 5, 6, 7, 8 ), and with secondly sub-configuration signal-generating means ( 31 ) which are designed for the distinguishable generation and delivery of a first sub-configuration signal (TI 1 ) and a second sub-configuration signal (TI 2 ), for each of the two sub-configurations ( 3, 4 ), there are provided thirdly coil signal-generating means ( 32 ) which are designed for the distinguishable generation and delivery of coil signals (S 1 , S 2 , S 3 , S 4 ) for the at least two coils ( 5, 6, 7, 8 ) of the respective sub-configuration ( 3, 4 ) on the basis of the respective sub-configuration signal (TI 1 , TI 2 ).
