1. A wireless device for dual-polarization beamforming, the wireless device comprising:
an antenna array comprising at least a pair of antenna elements; and
a baseband chain operatively connected to the antenna array,
wherein each pair of antenna elements comprises a first antenna element and a second antenna element of mutually orthogonal polarizations, and
wherein each pair of antenna elements is operatively connected to the baseband chain.
