摘要： A method is provided for using an antenna array to create two beams (a first beam and a second beam). In one aspect, the method uses dual polarization beam forming, which allows for many degrees of freedom in designing a desired power pattern. The method is well suited for systems with multiple radio chains (e.g., systems with active antennas). The method is also well suited for multi-port systems such as TD-SCDMA. In some embodiments, the method produces two beams where (a) the shape of the power beam pattern for the first beam and the shape of the power beam pattern for the second beam are the same (or substantially the same) in a plurality of directions of interest and (b) the beams have orthogonal (or substantially orthogonal) polarizations in the coverage area.

摘要： The present invention relates to a node (10) in a wireless communication system, the node (10) comprising an antenna array with at least first (11a) and second antenna elements (11b). First (12a-16a) and a second radio chains (12b-16b) connect the antenna elements (11a, 11b) to a base band (17). Oscillators (16a, 16b) feed a signal with a unique frequency band (f1, f2) to the splitter (14a, 14b) in the same radio chain. The splitters (14a, 14b) divides the signals into at least two signal parts and feed each part to the multiplexers (13a, 13b). Each multiplexer (13a, 13b) in the node (10) receives signal parts from each splitter (14a, 14b) in the node. The splitters (14a, 14b) weight the division of the signal into the signal parts in dependence of the frequency bands, such that a certain beam width is maintained in all frequency bands. Accordingly, the node provides the same coverage area over different fragmented bands in a reconfigurable antenna.
