Claim Text:
1. A node in a wireless communication network, the node comprising: at least two antenna columns which are physically separated from each other, each antenna column comprising at least one dual polarized antenna element, each antenna element having a first polarization and a second polarization, the first polarization and second polarization being mutually orthogonal, such that each antenna column comprises a first antenna port, associated with the first polarization, and a second antenna port, associated with the second polarization; and at least two four-port power dividers/combiners, each power divider/combiner having a first port pair and a second port pair, where, for each power divider/combiner, power input into any port in a port pair is isolated from the other port in said port pair, but divided between the ports in the other port pair, where antenna ports of antenna columns that are pair-wise physically separated, from those pairs of antenna columns with antenna columns that are most physically separated to those pairs of antenna columns with antenna columns that are least physically separated, in a falling order, are cross-wise connected to the first port pair in corresponding power dividers/combiners, such that each first port pair is associated with orthogonal polarizations of different antenna columns, wherein for at least one power divider/combiner, the ports in the second port pair are connected to a corresponding second phase altering device and third phase altering device, the phase altering devices that are connected to a certain power divider/combiner constituting a set of phase altering devices, and where one port in each second port pair is connected to a first power dividing/combining network and the other port in each second port pair is connected to a second power dividing/combining network each power dividing/combining network having a respective main input/output port.
