摘要： A dual-polarized antenna (10) with good isolation between feed ports (13a, 13b) and high similarity with respect to the radiation patterns is provided. An antenna (10) includes a patch (11), four symmetrically arranged feed structures (12a-12d, 15), two feed ports (13, 13b) and a feed network (14). Radiation pattern similarity is obtained by the pair-wise symmetrical, orthogonal layout of the feed structures (12a-12d, 15). Good isolation between feed ports (13a, 13b) is achieved through a feed network (14) divided into two network parts (14a, 14b) where each network part (14a, 14b) is designed so that each coupling between a network part (14a, 14b) and a feed structure (12a12d, 15) belonging to the other polarization is cancelled by a mirrored coupling with the other feed structure (12a-12d, 15) belonging to the polarization. In addition, a network part (14a, 14b) is laid out so that its corresponding feed structures (12a-12d, 15) are fed with supporting signals of equal magnitude.

摘要： A telecommunications system and method is disclosed for allowing a base station to simultaneously transmit signals in several beams of a multi-beam antenna configuration. Antenna pattern control is maintained by employing orthogonal polarization orientation for every other beam. For example, the two orthogonal polarization directions can be approximately linear polarization slanted ±45°. To be able to transmit simultaneously in an arbitrary combination of more than one beam, the BS antenna array includes a separate feeder cable for each combination of beams corresponding to a particular polarization, from one feeder per beam to one feeder with all beams of that polarization.

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.
