| 20100149068 | Dual Polarized Antenna With Null-Fill - The present invention relates to a dual polarized array antenna comprising at least two dual polarized antenna elements being arranged for radiating electromagnetic energy having a first polarization, constituting a first antenna radiation pattern, via a connection to a first antenna port, and electromagnetic energy having a second polarization, constituting a second antenna radiation pattern, via a connection to a second antenna port, the second polarization being orthogonal to the first polarization, the first antenna radiation pattern and second antenna radiation pattern each having a main beam and a number of side-lobes with nulls. The array antenna comprises at least one further dual polarized antenna element arranged for radiating electromagnetic energy having two mutually orthogonal polarizations, constituting further antenna radiation patterns, via respective connections to the first antenna port and the second antenna port, where the polarization of said at least one further dual polarized antenna element that is associated with the first antenna port deviates from the first polarization such that said at least one null of the first antenna pattern is at least partly filled. | 06-17-2010 |

| 20090184879 | Method and Device for Coupling Cancellation of Closely Spaced Antennas - An antenna system comprising at least two antenna radiating elements and respective reference ports the ports being defined by a symmetrical antenna scattering N×N matrix. The system further comprises a compensating network connected to the reference ports. The compensating network is arranged for counteracting coupling between the antenna radiating elements. The compensating network is defined by a symmetrical compensating scattering 2N×2N matrix comprising four N×N blocks, the two blocks on the main diagonal containing all zeros and the other two blocks of the other diagonal containing a unitary N×N matrix and its transpose. The product between the unitary matrix, the scattering N×N matrix and the transpose of the unitary matrix equals an N×N matrix which essentially is a diagonal matrix. The present invention also relates to a method for calculating a compensating scattering 2N×2N matrix for a compensating network for an antenna system. | 07-23-2009 |

| 20090010356 | Array Antenna Arrangement - The present invention relates to a wireless communication system, comprising at least one base station in a communication cell. The base station is equipped with at least one array antenna comprising at least two antenna ports which are coupled to respective at least two corresponding antenna Q elements, where at leas 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 UE (user equipment) in the cell. According to a certain aspect of the present invention, in a first mode 0 operation, the array antenna is arranged for communication via one antenna radiation lobe. The present invention also relates to a method for performing said communication. | 01-08-2009 |
