Patent attributes
A communication terminal may include an array of antenna modules. Each module may include an array of radiators on a substrate and a radio-frequency lens overlapping the array. The lens may include a tapered base on the substrate and a curved portion on the tapered base. The tapered base and curved portions may be rotationally symmetric about a central axis of the lens. The curved portion may be hemispherical. The tapered base portion may be conical and may have a first radius at the hemispherical portion and a second radius that is less than the first radius at the substrate. At least one radiator in the array may be located beyond the first radius and within the second radius from the central axis. The lens may be formed from lattice having interleaved layers of dielectric segments separated by gaps to reduce the overall weight of the module.
