Abstract
In order to achieve an optimal identification with an identification device for objects that comprise a transponder and are transported by means of a conveyor device through a closed tunnel (2), it is proposed that the antenna device of the transmitting and receiving device (10) comprises at least three sequentially arranged coil-shaped antennas (4, 6, 8). They surround the tunnel (2), each lying in a plane and representing a linearly independent system. The antennas (4, 6, 8) are operated in a multiplexer mode.
