Multi-channel communications antenna

Abstract

An antenna structure configured for simultaneous communication over multiple channels or with multiple locations. In certain examples the antenna system includes an antenna, such as a horn antenna, a lens, or a horn-lens combination, for example, and a focal plane array located near the focal point of the antenna. The focal plane array can be made up of a plurality of sub-wavelength elements, and is configured to simultaneously excite and/or receive a plurality of beams, each having an independent pointing angle to communicate with multiple fixed or non-fixed communication terminals in different locations.
