Abstract: A hollow light-weight, low-cost, and high-performance 3D Luneburg lens structure using partially-metalized thin film, string, threads, fiber or wire base metamaterial to implement the continuously varying relative permittivity profile, characteristic of Luneburg lens structures, is disclosed. The hollow light-weight lens structure is based on the effective medium approach and may be implemented by a number of means. Further, most of the volume of the lens structure is free-space, thus the weight of the lens is significantly less than conventional 3D Luneburg lens structures of the same dimensions.

Abstract: An antenna and manufacturing process for antennas produce radiating elements of desired size for certain frequency bands by bump mounting radiating elements to the printed circuit board substrate. Driving circuitry is stacked to save space. Also, the radiating elements are made using a different dielectric constant material as compared to the substrate. Tiling radiating elements or sub-arrays or radiating elements with bump mounting allows for spatial separation that eliminates surface waves. Bump mounted radiating elements also allow for multiple sizes of radiating elements in which smaller size provides lower directivity to cover broader beam scan performance.
