Abstract
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 (TI1) and a second sub-configuration signal (TI2), 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 (S1, S2, S3, S4) 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 (TI1, TI2).
