Abstract
The present invention is an electronically scannable antenna. The antenna includes a Radio Frequency (RF) element. The antenna also includes a screen which is configured at least substantially around the RF element. The screen includes a plurality of integrated switches which may be configured to allow the operating mode of the screen to be selectively and automatically switched between a transmissive mode and a reflective mode. When the screen is operating in the transmissive mode, the antenna is configured to provide an omni-directional beam. When the screen is operating in the reflective mode, the antenna is configured to provide a directional beam.
