Abstract
A multiple beam reflector antenna includes at least one reflector, a plurality of feed horns for feeding the at least one reflector, and a metamaterial lens interposed between the plurality of feed horns and the at least one reflector. The metamaterial lens may provide an overlapping element distribution from at least two feed horns of the plurality of feed horns. In one embodiment, the metamaterial lens has an index of refraction between about zero and about one.
Claims15
A multiple beam reflector antenna, comprising:
- at least one reflector,
- a plurality of feed horns feeding the at least one reflector, each feed horn of the plurality of feed horns terminating in a feed horn aperture;
- and
- a metamaterial lens interposed between the plurality of feed horns and the at least one reflector, wherein the metamaterial lens provides an overlapping element distribution from at least two feed horns of the plurality of feed horns.

A multiple beam reflector antenna, comprising:
- at least one reflector,
- a plurality of feed horns feeding the at least one reflector, each feed horn in the plurality of feed horns terminating in a feed horn aperture;
- and
- a metamaterial lens interposed between at least one feed horn aperture of the plurality of feed horns and the at least one reflector, wherein the metamaterial lens provides an overlapping element distribution from at least two feed horns of the plurality of feed horns.

A multiple beam reflector antenna, comprising:
- at least one reflector,
- a plurality of feed horns feeding the at least one reflector, each feed horn in the plurality of feed horns including a throat section that terminates in a substantially conical section, the substantially conical section flaring outwardly from the throat section and terminating in a feed horn aperture;
- and
- a metamaterial lens interposed between at least one feed horn aperture of the plurality of feed horns and the at least one reflector, wherein the metamaterial lens provides an overlapping element distribution from at least two feed horns of the plurality of feed horns.
