Abstract
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.
