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： An electronics unit for wireless transfer of signals, includes an antenna part, an electronics part, and a transmission circuit part. The electronics part is placed on a laminate with at least one substrate layer of a dielectric material. The substrate layer is made of a flexible material and forms a continuous unit, including a first part which supports the electronics part, a second part which supports the antenna part, and a third part which supports the transmission circuit part. The second part of the substrate is formed to shape a convex surface, which supports groups of at least one antenna element. Since the surface is curved, the groups cover different directions.

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： 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.

A feeding network is provided which comprises a number of phase ports, a number of which form first phase ports connected to a number of transceiver means for downlink communication and a number of which form second phase ports connected to a number of transceiver means for uplink communication. The feeding network comprises a number of antenna ports connected to antenna elements and the feeding network generates substantially independent, orthogonal signals to provide for phase diversity and the antenna elements are arranged to form at least one cylindrical array antenna. The invention also relates to a method of providing communication between an omnidirectional base station antenna arrangement with a number of antenna elements and a number of transceiver means and a number of user stations as well as to a method of providing for at least phase diversity transmission at an omnidirectional base station antenna arrangement.
