摘要： In a system (1) with a lock (2) and a key (3) the lock (2) is provided with a write/read device (13) and a write/read coil (19) connected thereto, and the key (3) is provided with a transponder unit (14) and a transponder coil (32) which is connected thereto; the two coils (19, 32) are inductively coupled when the key (3) has been inserted into the lock (2) and occupy a position relative to one another in which the coil axis (20) of the write/read coil (19) and the coil axis (33) of the transponder coil (32) enclose an acute angle (α).

摘要： An antenna (1) for communication with a multitude of transponders (6a..6c) is provided, the antenna (1) having an antenna conductor (2) which completely encloses at least one read/write region (4c) intended for a transponder (6c) individually and/or, when a multitude of read/write regions (4a, 4b) are arranged within a continuous inner region (3) enclosed by the antenna conductor (2), the inner region (3) has constrictions (5a) between the read/write regions (4a, 4b) so that the antenna conductor (2) largely encloses these read/write regions (4a, 4b) individually. The electromagnetic field radiated by the antenna (1) is thereby concentrated on the read/write regions (4a..4c).
