Patent ID: 7420525

Claim:
Multi-beam antenna providing a plurality of radiation beams, each radiation beam having a shape and angular direction relative to the antenna, the multi-beam antenna comprising: a dielectric lens having a surface, and defined physical and dielectric characteristics; an antenna feed configuration comprising a plurality of waveguide feeds, each waveguide feed having a physical structure for propagating electromagnetic energy at a selected frequency, and opposing ends with one end forming a feed port and the other end forming a feed aperture contiguous with the dielectric lens at a predetermined position along the lens surface; and wherein the shape and angular direction of each of the plurality of radiation beams of the multi-beam antenna are determined by the physical and dielectric characteristics of the dielectric lens, the position the feed aperture a corresponding one of the waveguide feeds on the surface of the dielectric lens, and the frequency of electromagnetic energy propagating in the corresponding one of the waveguide feeds.
