发明名称 Antenna for communication with a multitude of transponders
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).
