摘要： To improve null depths in an antenna pattern of a first polarization, formed with nulls in at least one angular region, a further antenna pattern of a second polarization, substantially orthogonal to the first polarization, is concurrently formed. In the angular region, the amplitudes of the copolar components of the further antenna pattern are substantially equal to the amplitudes of the crosspolar components of the antenna pattern of the first polarization, and the phases of the copolar components of the further antenna pattern of the second polarization are substantially opposite to the phases of the crosspolar component of the first polarization.

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 beam pattern associated with a multi-beam antenna array is adjusted if a first beam of the beam pattern is overloaded. A lobe of a second beam of the beam pattern can be steered away from a main lobe of the first beam. Also, if a user is located in an area covered by a second beam which is adjacent to the first beam, a third beam of the beam pattern can be selected for effectuating communication with the user. If a user is located in an area covered by the first beam, another beam of the beam pattern can be selected for effectuating communication with the user.
