MULTI-BEAM ANTENNA WITH MODULAR LUNEBURG LENS AND METHOD OF LENS MANUFACTURE

摘要

A multiple beam antenna system is described. The system may include a mounting structure, a first wireless access antenna, a second wireless access antenna, and a radio frequency lens. The first and second wireless access antennas may be mounted to the mounting structure. Columns of radiating elements of the first and second wireless access antennas may be aligned with the radio frequency lens. The radio frequency lens may be modular in a longitudinal or radial direction, or in both directions. The radio frequency lens may include a plurality of compartments arranged to form a first cylinder made up of concentric, coaxial cylinders and a plurality of dielectric materials in at least some of the plurality of compartments.
