First Claim
Patent Images
1. A method for controlling the direction of a beam radiated by an array of antenna elements using aperture control shutters, comprising:
- overlaying an array of aperture control shutters (ACSs) on the array of antenna elements, each ACS substantially covering an antenna element; and
controlling whether an antenna element radiates by controlling whether each individual ACS is open or closed by a signal provided to each ACS.

Abstract
Embodiments include systems and methods for controlling beam direction of an array of antenna elements in a wireless communications system. In one embodiment, aperture control shutters substantially cover each radiating antenna element. Each aperture control shutter is selectively turned on or off to control the direction of a beam of the antenna array.

9. A system for facilitating communication between a host device and a peripheral device by controlling an electromagnetic beam direction of an array of antenna elements, comprising:
-
an array of aperture control shutters (ACSs), each ACS substantially covering an element of the antenna array; and a control mechanism for selecting at least one ACS to allow radiation from the element it covers in order to provide a directed beam to a peripheral device for communication between the host device and the peripheral device.
