Abstract:
It is provided a node in a wireless communication system comprising an analog architecture for achieving vertical sectorization. The node comprises at least four main input/output ports ( 1, 2, 3, 4 ), a power splitting stage ( 5 ), at least one power redistribution stage ( 20 ) and a plurality of pairwise arranged dual polarized antennas ( 31, 32, 33, 34 ).

Claim (Index 1):
A node for a wireless communication system comprising:\n at least four main input/output ports, half of the ports being associated with a first polarization and the other half of the ports being associated with a second polarization; a power splitting stage comprising at least four 1+N port power dividers/combiners, one divider/combiner connected to each main input/output port, each power divider/combiner comprising an input/output and N outputs/inputs, N>1, wherein each power divider/combiner output comprises a controllable phase altering device configured to change a phase of a signal received at the power divider/combiner input/output; a first power redistribution stage comprising a plurality of 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; a plurality of pairwise arranged dual polarized antennas, each antenna having a first polarization antenna element and a second polarization antenna element, the first polarization and second polarization being mutually orthogonal, such that each antenna comprises a first antenna port associated with the corresponding first polarization antenna element, and a second antenna port, associated with the corresponding second polarization antenna element, wherein wherein the plurality of power dividers/combiners are pairwise arranged, each pair comprising a first polarization power divider/combiner and a second polarization power divider/combiner, a first port pair of each power divider/combiner in the first power redistribution stage is communicatively coupled to the main input/output ports of the corresponding polarization, each pair of power dividers/combiners is connected to an antenna pair such that a second port pair of a first polarization power divider/combiner is connected to first polarization antenna elements of the antennas in the corresponding antenna pair, and a second port pair of a second polarization power divider/combiner is connected to second polarization antenna elements in the antenna pair, and one port of the second port pair of each power divider/combiner connected to the corresponding antenna element comprises a phase altering device configured to introduce an adjustable phase shift of the port.
