摘要： A communication device includes a system board that includes a plurality of chips. Each chip in plurality of chips includes a plurality of antennas. A system board cover coupled to system board includes a plurality of lenses. Each lens is configured to cover an antenna of plurality of antennas as a radome enclosure. Each lens includes a base and a first tubular membrane coupled to base. A second membrane is coupled to the first tubular membrane. A support structure is coupled to the first tubular membrane. The support structure facilitates coupling of plurality of lenses to system board cover. The system board cover includes a feeder array that includes a plurality of antenna elements that are positioned at a proximal distance from base of a lens and the proximal distance of the system board from the base of the lens is less than a focal length of the lens.

摘要： A communication device includes a first lens, a feeder array, and control circuitry communicatively coupled to the feeder array. The first lens is associated with a defined shape, which further exhibits a defined distribution of dielectric constant. The feeder array includes a plurality of antenna elements that are positioned in proximity to the first lens. The control circuitry equalizes a distribution of a gain from the received first lens-guided beam of input RF signals across the feeder array and different scan directions of the plurality of antenna elements. The equalized distribution of gain is based on the defined distribution of dielectric constant within the first lens and the proximity of the feeder array to the first lens.

摘要： A communication device includes a lens having a defined shape. 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. The specified proximal distance is less than a focal length of the lens. The lens covers the feeder array as a radome enclosure. 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.
