Abstract:
1. A node in a wireless communication system, the node comprising at least one antenna, where the at least one antenna comprises an even number of antenna ports, the number being at least four, where each antenna port is associated with a corresponding polarization, beam-width and phase center, wherein the antenna ports are connected to a reconfiguration network which is arranged for pair-wise linear combination of antenna ports of mutually orthogonal polarizations to a number of virtual antenna ports, wherein each virtual antenna port is connected by the reconfiguration network to a pair of the antenna ports and each antenna port is connected by the reconfiguration network to a single virtual antenna port, the number of virtual antenna ports being equal to half the number of antenna ports, where the virtual antenna ports correspond to virtual antennas, the virtual antenna ports being connected to corresponding radio branches.
