An active antenna device includes a terminal for receiving a signal to be transmitted, and an antenna for generating a radio signal based on the signal to be transmitted. The active antenna device further includes a controller that is configured to control the antenna depending on the intended properties of the radio signal. The active antenna device includes a coupler between the terminal and the antenna that is configured to decouple a signal portion from the signal to be transmitted. The active antenna device further includes an energy converter that is connected between the coupler and the controller and configured to provide a power signal for the operation of the controller based on the decoupled signal portion.

Embodiments of the present invention provide a device for monitoring access to a storage area of a plurality of storage areas for goods, including a measurement signal generation, detection, and evaluator. The measurement signal generator includes a signal source and a conductor loop arrangement, the detector for detecting the generated magnetic field is configured to provide a measurement signal on the basis of the detected magnetic field, and the evaluator for evaluating the measurement signal is configured to determine an instance of access to one of the storage areas on the basis of the measurement signal, to compare a determined instance of access with a target access instance, and to output a display signal on the basis of the comparison.
