Abstract

There is provided mechanisms for beam forming using an antenna array comprising dual polarized elements. A method comprises generating one or two beam ports, wherein the one or two beam ports are defined by combining at least two non-overlapping subarrays. Each subarray has two subarray ports, the two subarray ports having identical power patterns and mutually orthogonal polarization. The at least two non-overlapping subarrays are combined via expansion weights. The expansion weights map the one or two beam ports to subarray ports such that the one or two beam ports have the same power pattern as the subarrays. At least some of the expansion weights have identical non-zero magnitude and are related in phase to form a transmission lobe. The method comprises transmitting signals using said one or two beam ports.
