An antenna arrangement with two horizontal and two vertical array antennas. A first horizontal antenna port and a second vertical antenna port are connected to a first polarization. A first vertical antenna port and a second horizontal antenna port are connected to an orthogonal second polarization. Each port is connected to corresponding antenna elements. The first horizontal antenna port and the first vertical antenna port are connected in phase. The second horizontal antenna port and the second vertical antenna port are connected with opposite phases. A plurality of antenna element symmetry pairs are formed with respect to a common symmetry point. Certain weights are applied to the antenna elements of each symmetry pair, where a weight for a certain polarization in an antenna element in a symmetry pair comprises the complex conjugated weight for an orthogonal polarization in the other antenna element in the symmetry pair.
