Patent ID: 6942148

Claim:
A communication device ( 1 ) for the communication with at least one data carrier which can be brought into a communication field of the communication device, and with a coil configuration ( 2 ) which has two opposing sub-configurations ( 3 , 4 ) by means of which the communication field operative between the two sub-configuration ( 3 , 4 ) can be generated, and with 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 a respective one of the two sub-configurations ( 3 , 4 ), wherein each of the two sub-configurations ( 3 , 4 ) has at least two coils ( 5 , 6 , 7 , 8 ) and coil signal-generating means ( 32 ) are provided 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 ), wherein each of the coils ( 5 , 6 , 7 , 8 ) has two coil terminals ( 19 , 18 , 21 , 22 , 24 , 25 , 27 , 28 ) and the two coil terminals ( 19 , 18 , 21 , 22 , 24 , 25 , 27 , 28 ) of each coil ( 5 , 6 , 7 , 8 ) are arranged in a coil central area ( 9 A, 9 B, 10 A, 10 B) and are connected to adaptation means ( 20 , 23 , 26 , 29 ) and the coil signal-generating means ( 32 ) are designed for the delivery of the respective coil signal (S 1 , S 2 , S 3 , S 4 ) to said adaptation means ( 20 , 23 , 26 , 29 ) connected to a coil ( 5 , 6 , 7 , 8 ), each said adaptation means being located in the same sub-configuration as the coil it drives, said generation means located external to either of said sub-configurations, and each said adaptation means designed for the reception of the respective coil signal from the generation means and sending of a corresponding current to the respective coil.
