Abstract
A system and method for a wireless link to a remote receiver includes a communication device for generating RF and a planar antenna apparatus for transmitting the RF. The planar antenna apparatus includes selectable antenna elements, each of which has gain and a directional radiation pattern. The directional radiation pattern is substantially in the plane of the antenna apparatus. Switching different antenna elements results in a configurable radiation pattern. Alternatively, selecting all or substantially all elements results in an omnidirectional radiation pattern. One or more directors and/or one or more reflectors may be included to constrict the directional radiation pattern. The antenna apparatus may be conformally mounted to a housing containing the communication device and the antenna apparatus.
