| 摘要 |
<p>The present invention relates to a node (1) in a wireless communication network, the node (1) comprising at least two antenna columns (2, 3) which are physically separated from each other, each antenna column (2, 3) comprising at least one dual polarized antenna element (4a, 4b, 4c, 4d; 5a, 5b, 5c, 5d). Each antenna element (4a, 4b, 4c, 4d; 5a, 5b, 5c, 5d) has a first polarization (P1) and a second polarization (P2). The node (1) further comprises at least two four-port power dividers/combiners (10, 11), each power divider/combiner (10, 11) having a first port pair (12, 13) and a second port pair (14, 15), where, for each power divider/combiner (10, 11), power input into any port in a port pair is isolated from the other port in said port pair, but divided between the ports in the other port pair. Antenna ports (6, 7; 8, 9) of antenna columns (2, 3) that are pair-wise physically separated, from those pairs of antenna columns that are most physically separated to those that are least physically separated, are cross-wise connected to the first port pair (12, 13) in corresponding power dividers/combiners (10, 11). For at least one power divider/combiner (11), the ports in the second port pair (15) are connected to a corresponding second phase altering device (17) and third phase altering device (18).</p> |
