Abstract

A device includes an antenna array with at least four antennas, wherein each antenna has its own feeder line terminal, wherein the feeder line terminals of antennas arranged directly adjacent to one another are geometrically offset from one another by 90° in each case. The device further includes a control device configured to feed the individual antennas via their respective feeder line terminals such that the antenna array exhibits different radiation patterns at different points in time. A first radiation pattern shows a polarized field distribution. According to the invention, a second radiation pattern exhibits an unpolarized field distribution.
