Abstract
There is presented a wireless device for dual-polarization beamforming. The wireless device comprises an antenna array. The antenna array comprises antenna elements of mutually orthogonal polarizations and a baseband chain. The antenna elements of both polarizations are operatively connected to the baseband chain. There is also presented a method for dual-polarization beamforming as performed by such a wireless device.
