Patent ID: 8791853

Claim:
A directional antenna, comprising: a support structure for defining a generally planar support surface; a first planar antenna stack positioned on the generally planar support surface, the first planar antenna stack having a plurality of antenna elements, the plurality of antenna elements of the first planar antenna stack being oriented in a first orientation, allowing the first planar antenna stack to concentrate radiations in a first direction; a second planar antenna stack positioned on the generally planar support surface, the second planar antenna stack having a plurality of antenna elements, the plurality of antenna elements of the second planar antenna stack being oriented in a second orientation, the second orientation being rotated a predetermined angle with respect to the first orientation, allowing the second planar antenna stack to concentrate radiations in a second direction different from the first direction; and a controller communicatively connected with the first planar antenna stack and the second planar antenna stack, the controller being configured for selectively activating at least one of: the first planar antenna stack for concentrating radiations of the directional antenna in the first direction, or the second planar antenna stack for concentrating radiations of the directional antenna in the second direction.
