Abstract
In one embodiment, the present invention provides a configurable ground plane for a matched antenna so that by configuring or changing the ground plane shape in a controlled manner, a change in the radiation pattern can be achieved such that the main beam of the antenna is steered in a particular direction, and a null in another direction. According to one aspect of the present invention, antennas such as monopole or patch antennas with a configurable ground plane of the present invention with a plurality of configurable sectors can be made to change in shape, size and conductivity. Such ground plane modifications can be used to select the direction of maximum gain away from a direction of interference, such in the case of tactical jamming. Likewise, the ground plane modifications can be used to steer the maximum directivity of an antenna in a desired direction for increased signal integrity.
