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