Patent ID: 7548764

Claim:
A system comprising: an antenna array having one or more comprising a plurality of antennas configured to provide a first narrow beamwidth radiation pattern based on first antennas weights and a second wide beamwidth radiation pattern based on second antenna weights; a transform matrix configured to be coupled to the antenna array and to transform one or more inputs into one or more outputs according to a transform function that transforms the first antenna weights and second antenna weights into respective first and second input weights that are applied to first and second sets of signals, respectively, to be transmitted, and to output, wherein the outputs of the transform matrix provide signals to the antennas of the antenna array with predetermined phases and magnitudes for generating in order to generate the first narrow beamwidth and second wide beamwidth radiation patterns simultaneously; and a transmitter configured to provide the first set of signals to be transmitted with the first narrow beamwidth radiation pattern and the second set of signals to be transmitted with the second wide beamwidth radiation pattern to inputs of the transform matrix.
