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.

Radio frequency emission pattern shaping

A spacing member is positioned between a pair of antenna members. The two antenna members may be horizontally polarized or vertically polarized and positioned next to each other to provide an increased gain. The spacing element may be placed between the antenna members and have a thickness corresponding to the characteristic impedance of the antenna transmission line. The characteristic impedance may be determined based on the width of the transmission line. The spacing member may be radio-frequency (RF) transparent and may adhere to either or both of the antenna elements. The spacing member may be implemented as a plastic double sided tape or a uniform piece of plastic having one or more adhesive layers.
