WIRELESS COMMUNICATION SYSTEM NODE WITH RE-CONFIGURABLE ANTENNA DEVICES

摘要

The invention relates to a node in a wireless communication system, where the node comprises at least one antenna arrangement. Each antenna arrangement comprises a first, second, third and fourth antenna device positioned one after the other. Each antenna device comprises at least a corresponding first antenna port connected to a first polarization of the corresponding antenna device, the first antenna device and the second antenna device forming a first antenna device pair, and the third antenna device and the fourth antenna device forming a second antenna device pair. For each antenna device pair, the first antenna ports are at least indirectly connected to at least one respective controllable power divider/combiner having a respective common port. Each controllable power divider/combiner is arranged to adjust and/or set a corresponding power relation between the first antenna ports of the corresponding antenna device pair for power received and/or transmitted at its common port.
