A wireless communication system comprising at least one base station in a communication cell, wherein the base station is equipped with at least one array antenna comprising at least two antenna ports which are connected to respective at least two corresponding antenna elements, wherein at least two of the at least two antenna elements have essentially the same polarization. The array antenna is arranged for communication via at least two antenna radiation lobes, each antenna radiation lobe communicating an information stream to at least one user equipment (UE) in the cell, wherein each antenna radiation lobe is individually controllable both in azimuth and elevation, whereby the communication of the information streams is optimized.

Array antenna arrangement

An antenna arrangement comprising an input/output connection and a first and a second tuning network with different transfer functions. The arrangement additionally comprises an antenna and a switch for connecting the input/output connection of the arrangement to one of said tuning networks, with a second switch for connecting the antenna of the arrangement to the tuning network to which the input/output connection of the arrangement has been connected. The arrangement comprises a sensor for sensing a form factor of the arrangement or of an apparatus in which the arrangement is used, and said sensor can be used for influencing said first and second switches, so that a device which has been connected to the arrangement may be connected to the antenna via a tuning network optimal for the current form factor of the arrangement.

Antenna switching arrangement

An electronic device () comprising an antenna arrangement with first and second antenna groups with first () and a second () radiation elements. The first and second radiation elements in each group have first and second respective polarizations and gain, and said groups also comprise a beam forming network () connected to the radiation elements of the group and to an output selector (). The beam forming network () of each antenna group uses the radiation elements () in the group to create a radiation pattern () with a polarization which is a composite of the first and second polarizations of the elements in the group, so that a first () and a second () radiation pattern of composite polarization is created. The output selector () selects or combines signals received by the two antenna groups as its output.
