Abstract
An antenna device has a radiating unit having a plurality of antennas, configured to emit a radio signal with a radiation pattern. In addition, the antenna device has a calculator configured to generate and to apply to the plurality of antennas a plurality of feed signals based on an identification signal provided in order to generate the radio signal. The calculator is additionally configured to control the feed signals in a time-varying manner so that the radio signal is emitted with a time-varying radiation pattern.
