    Abstract: The present invention relates to a system for changing the radiation pattern shape of an antenna array 83; 88 during electrical tilting. The antenna array 83; 88 has multiple antenna elements 84, and the system comprises a phase- shifting device 10; 20; 40; 85 provided with a primary port 11 configured to receive a transmit signal, and multiple secondary ports 121- 124; 12 configured to provide phase shifted output signals to each antenna element 84. The system further comprises a phase-taper device 20; 40; 85; 87 that changes phase taper over the antenna elements, and thus the beam shape, with tilt angle ?. The invention is adapted for use in down-link as well as up-link within a wireless communication system.

    Abstract: The present invention relates to a sub-node (15, 25, 30), such as a repeater station or relay station, equipped with a multi-beam sub-node link antenna (16; 26A, 26B; 31, 32). The beams of the sub-node link antenna allow communication between the sub-node and at least two nodes (access points/base stations) 11A-B; 11A-E. The sub-node is further provided with at least one transmitting and receiving coverage antenna (17; 27; 37) to generate coverage in at least one geographical secondary coverage area a; a-c, and a control mechanism that selects one of the nodes to extend the geographical primary coverage area A-B; A-E of the node 11A-B; 11A-E to include the geographical secondary coverage area a; a-c of the sub-node (15, 25, 30). The invention is also related to a cellular communication network (10, 20, 90), and a method for generating coverage in a cellular communication network.
