High-gain, wide-angle, multi-beam, multi-frequency beamforming lens antenna
A high-gain, wide-angle, multi-beam, multi-frequency beamforming lens antenna that includes a Luneburg lens with at least one planar interface in the southern hemisphere of the Luneburg lens and a planar ultrawideband modular antenna (PUMA array) structure. The PUMA array structure is connected to at least one of the planar interfaces of the Luneburg lens and is configured to function as a feed network to illuminate cells of the Luneburg lens simultaneously.
1 . A high-gain, wide-angle, multi-beam, multi-frequency beamforming lens antenna system comprising:
a Luneburg lens with at least one planar interface in a southern hemisphere of the Luneburg lens; and
at least one planar ultrawideband modular array (PUMA array) structure is operatively coupled to the planar interface, wherein the PUMA array structure is configured to function as a feed network to illuminate at least one or more beams of the Luneburg lens simultaneously;
wherein the antenna is communicably coupled between multiple networks operating at different frequencies.
2 . The antenna of claim 1 , wherein the PUMA array structure is matched to the Luneburg lens to form a single layer of material between dipole layers of the PUMA array structure and the Luneburg lens.
3 . The antenna of claim 1 , wherein feed elements of the PUMA array structure are spaced unevenly.
4 . The antenna of claim 3 , wherein each feed element of the feed elements operates independently of adjacent elements.
5 . The antenna of claim 1 , wherein an illumination in a direction is at least increased or decreased via adjusting a positioning of the planar interface.
6 . The antenna of claim 1 , wherein the Luneburg lens is discretized into multiple dielectric layers and each layer has a discrete dielectric constant.
7 . The antenna of claim 1 , wherein the dielectric layers are cast individually, nested together, and assembled using an adhesive.
8 . The antenna of claim 1 , wherein the Luneburg lens comprises polyoxymethylene POM, polycarbonate resin thermoplastic, or a combination thereof.
