Abstract: 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.

Abstract: A telecommunications system and method is disclosed for allowing a base station to simultaneously transmit signal in several beams (1, 2, 3, 4) of a multi-beam antenna configuration. Antenna pattern control is maintained by employing orthogonal polarization orientation for every other beam (1, 2, 3, 4). For example, the two orthogonal polarization directions can be approximately linear polarization slanted +/- 45 DEG . To be able to transmit simultaneously in an arbitrary combination of more than one beam (1, 2, 3, 4), the BS antenna array includes a separate feeder cable (30c, 30f) for each combination of beams (1, 2, 3, 4) corresponding to a particular polarization, from one feeder (30) per beam (1, 2, 3, 4) to one feeder (30) with all beams (1, 2, 3, 4) of that polarization.

Abstract: An antenna arrangement and a method for obtaining such an antenna arrangement are disclosed. The antenna arrangement utilizes the beam ports of a beam forming network, e.g. a Butler matrix, in connection with a multi-element radiator antenna for obtaining receive/transmit channels having more antenna beams within a desired coverage. At least one extra signal combiner is utilized for combining at least one beam port of a number of ordinary beam ports with a nonadjacent beam port to form one receive/transmit channel in a number of desired receive/transmit channels. The particular receive/transmit channel uses the at least one extra signal combiner for combining at least one of a number of ordinary beam ports with a nonadjacent beam port normally being terminated, for adapting power and sensitivity distributions for a desired cell coverage or for desired coverage of overlapping cells.

Abstract: 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.
