1. A multi-beam antenna, comprising:

  • a. a dielectric substrate, wherein said dielectric substrate comprises a conical surface; and

    b. a plurality of antenna elements on said dielectric substrate, wherein at least two of said plurality of antenna elements each comprise an end-fire antenna adapted to launch, receive, or launch and receive electromagnetic waves in or from a direction substantially away from an edge of said dielectric substrate and substantially parallel thereto so that a directivity of said multi-beam antenna is oriented upwards in elevation relative to an associated axis of revolution of said conical surface, and said direction for at least one said end-fire antenna is different from said direction for at least another said end-fire antenna.
