Abstract

It is described an antenna arrangement for transmitting and/or for receiving electromagnetic radiation. The antenna arrangement includes two antenna elements, which are adapted for transmitting and/or for receiving electromagnetic radiation of a first polarization. The antenna arrangement further includes one antenna element, which is adapted for transmitting and/or for receiving electromagnetic radiation of a second polarization being different from the first polarization. Furthermore, there is provided one coupling unit, which is adapted to couple, based on an appropriate control signal, the antenna elements selectively with one terminal of the antenna arrangement in such a manner, that the polarization direction of the antenna arrangement can be adjusted to the first polarization or to a combination of the first and the second polarization.
