Abstract
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.
