Abstract

There is provided an antenna arrangement for a radio transceiver device for simultaneous use of two polarization directions. The antenna arrangement comprises at least two baseband chains. The antenna arrangement further comprises a first set of antenna elements of a first polarization direction, and a second set of antenna elements of a second polarization direction. The antenna arrangement comprises an analog distribution network operatively connecting the at least two baseband chains to both sets of antenna elements. All of the baseband chains are operatively connected to each respective antenna element of the first set and to each respective antenna element of the second set via the analog distribution network.
