Abstract
A high gain, multi-beam lens antenna system for future fifth generation (5G) wireless networks. The lens antenna includes a spherical dielectric lens fed with a plurality of radiating antenna elements. The elements are arranged around the exterior surface of the lens at a fixed offset with a predetermined angular displacement between each element. The number of beams and crossover levels between adjacent beams are determined by the dielectric properties and electrical size of the lens. The spherical nature of the dielectric lens provides a focal surface allowing the elements to be rotated around the lens with no degradation in performance. The antenna system supports wideband and multiband operation with multiple polarizations making it ideal for future 5G wireless networks.
Claims21
A directive, multiple beam MIMO antenna system for 5G wireless voice and high speed data communications, the system comprising:
- a spherical dielectric lens;
- a plurality of dual polarized antenna elements;
- one or more element support structures that support said plurality of dual polarized antenna elements;
- and
- one or more positioning systems for selectively moving the one or more element support structures in a rotational manner with respect to a center of the spherical dielectric lens to modify the position of said plurality of antenna elements and their corresponding secondary beams altering the coverage area provided by said MIMO antenna
- wherein two or more of the plurality of antenna elements are electronically combined to modify secondary beam shape and position.
