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 is directed to cellular systems and methods for providing a multi-beam antenna configuration (50) within a base station without utilizing duplex filters. The multi-beam antenna configuration (50) of the present invention produces overlaid beams (1, 2, 3, 4) in both the uplink and downlink to cover the same area. Each beam (1, 2, 3, 4) has orthogonally oriented polarization directions (e.g., linear polarized slanted +45E) for the uplink and downlink. Adjacent uplink beams (1, 2, 3, 4) shall also have shifted polarization directions in order to attain polarization diversity between different beams (1, 2, 3, 4). In order to implement this polarization configuration, for each beam (1, 2, 3, 4), there is a selective filter (60) in front of the low noise amplifier (40a) for the uplink, and no duplex filter in front of the amplifier (40b) in the downlink direction.
