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.
