MULTIBAND OMNIDIRECTIONAL PLANAR ANTENNA APPARATUS WITH SELECTABLE ELEMENTS

摘要

A system (100) and method for a wireless link to a remote receiver includes a multiband communication device (120) for generating R and a multiband planar antenna apparatus (110) for transmitting the RF. The multiband planar antenna apparatus (110) includes selectable antenna elements, each of which has gain and a directional radiation pattern. Switching different antenna elements results in configurable radiation pattern. One or more directors and/or one or more reflectors may be included to constrict the directional radiatio pattern. A multiband coupling network selectively couples the multiband communication device (120) and the multiband planar antenna apparatus (110).
