The present invention relates to a user terminal device comprising a first and second antenna arrangement and a first and second radio chain arrangement. The first antenna arrangement comprises at least a first antenna element and a first and second antenna port. The second antenna arrangement comprises a third and fourth antenna port, a first polarized antenna element arranged for transmitting and/or receiving signals at a first polarization via the third antenna port and a second polarized antenna element arranged for transmitting and/or receiving signals at a second polarization via the fourth antenna port. The polarizations are mutually orthogonal in at least one direction. A first switching device is arranged to connect the first radio chain arrangement with either the first or third antenna port, and a second switching device is arranged to connect the second radio chain arrangement with either the second or fourth antenna port.
