ABSTRACT:
A base station including an antenna array that can be used to generate multiple well separated pencil radiation beams. Alternatively, these beams can be combined, without significant loss, to create a wide angle beam. Non-orthogonal beams (i.e. beams with significant spatial overlap) may be combined without significant field cancellation. The result is a single antenna array that can be used to transmit (or receive) different information on different beams (using every other beam) at the same frequency or alternatively it can be used for transmitting exactly the same information on all beams or on several beams that cover a sector.
