Abstract
Pattern shaping elements shape a radiation pattern generated by one or more antennas. A MIMO antenna system generates an omnidirectional radiation pattern. One or more pattern shaping elements may include metal objects which act as directors or reflectors to shape the radiation pattern. The shaping may be controlled by selectively coupling the pattern shaping elements to a ground plane, thus making them appear transparent to the radiation pattern. The pattern shaping elements may be amorphous, have varying shape, and may be symmetrical or asymmetrical. Different configurations of selected pattern shaping elements may provide different shapes for a radiation pattern.
