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.
