Abstract:
1. An antenna array suitable for use in a base station in a wireless communications network, the antenna array having a first beamforming arrangement for producing a plurality of dual polar uplink beams and a second beamforming arrangement for producing a plurality of dual polar downlink beams, wherein the dual polar uplink beams and the dual polar downlink beams have antenna gain that varies with direction, wherein the dual polar uplink beams are distinguished from the dual polar downlink beams in shape, wherein the number of the dual polar uplink beams is greater than the number of the dual polar downlink beams, wherein the first and second beamforming arrangements are different from one another and feed a common antenna array to produce the dual polar uplink and dual polar downlink beams and wherein both the first and the second beamforming arrangements are connected within a transceiver.
