Abstract
Techniques are provided herein for generating multiple radiation patterns. An antenna system comprises an antenna array having one or more antennas for providing a first radiation pattern and a second radiation pattern, a transform matrix for transforming one or more inputs into one or more outputs according to a transform function, wherein the outputs of the transform matrix provide signals to the antennas with predetermined phases and magnitudes for generating the first and second radiation patterns, and a transmitter for providing a first set of signals corresponding to the first radiation pattern and a second set of signals corresponding to the second radiation pattern to inputs of the transform matrix.
