  • Patent number: 11799530
    Abstract: A method is provided. The method includes determining a set of beam indexes including a first beam index and a second beam index; and determining a set of candidate matching networks. The method further includes performing an assigning step, where the assigning step includes: (a1) assigning a first matching network from the set of candidate matching networks to a first beam index; and (a2) assigning a second matching network from the set of candidate matching networks to a second beam index. The first matching network is different from the second matching network.

  • Patent number: 9653795
    Abstract: 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 has a first polarization and a second polarization. The node further comprises 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. Antenna ports of antenna columns that are pair-wise physically separated, from those pairs of antenna columns that are most physically separated to those that are least physically separated, are cross-wise connected to the first port pair in corresponding power dividers/combiners.

  • Patent number: 8457697
    Abstract: 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.
