Patent ID: 6999035

Claim:
An antenna device comprising: a reflector; a receiver receiving reflected radio waves from one side of the reflector, wherein the one side of the reflector includes a plurality of lenses, the plurality of lenses including at least a first lens with a first radio wave reflective characteristic and a second lens with a second radio wave reflective characteristic, the first and second radio wave reflective characteristics being different to selectively reflect radio waves with particular frequency ranges to the receiver; a third lens having a third radio wave reflective characteristic which is different from the first and second radio wave reflective characteristics to selectively reflect radio waves with particular frequency ranges to the receiver; a fourth lens having a fourth radio wave reflective characteristic which is different from the first, second and third radio wave reflective characteristics to selectively reflect radio waves with particular frequency ranges to the receiver; and an array of each of said first, second, third, and fourth lenses on the one side of the reflector.
