1. A communication device, comprising:
a lens having a defined shape; and
a feeder array comprising a plurality of antenna elements that are positioned in a specified proximal distance from the lens to receive a lens-guided beam of input radio frequency (RF) signals through the lens,
wherein the specified proximal distance is less than a focal length of the lens, and
wherein the lens covers the feeder array as a radome enclosure, and
wherein a distribution of a gain from the received lens-guided beam of input RF signals is substantially equalized from a radiation surplus region to a radiation deficient region of the feeder array to increase at least a reception sensitivity of the plurality of antenna elements for at least the lens-guided beam of input RF signals, based on the defined shape of the lens and the specified proximal distance of the feeder array to the lens, and wherein the radiation surplus region corresponds to a center area of the feeder array and the radiation deficient region corresponds to a plurality of edge areas of the feeder array.
