In addition, the cost of hand-pasted glass fiber reinforced plastic lens radomes is very expensive, and the hand-pasted process easily causes uneven wall thickness of the radome, which in turn causes poor electrical performance.

Chinese patent CN209266574U discloses a dielectric lens multi-beam antenna device, which comprises a dielectric lens column, an array antenna, an outer cover, an end cover and a mounting bracket, wherein the outer cover is an integrated antenna outer cover; the dielectric lens column and the array antenna are together covered in the outer cover; the end covers are positioned at two ends of the outer cover; the housing is mounted on a mounting bracket. This patent is divided into antenna dustcoat, upper end cover and bottom end cover with the antenna house split and is separately designed, has following shortcoming: 1. because the lens material is mainly supported by the lower end cover, the lower end cover is connected with the outer cover and is bonded by waterproof silica gel after the lower end cover and the outer cover are connected by rivets or screws, when the weight of the lens material is too large (exceeding 30 kg), the design easily causes that the weight of the lens material cannot be supported, and after the lens material is aged gradually along with outdoor use, the risk is greatly increased, if the lens material is used outdoors for a long time, the lens material is easy to fall off, the waterproof performance of the whole antenna is easy to fail, and the antenna cannot work. 2. The special-shaped structure easily causes that the pultrusion process is very complicated or impossible to manufacture, the cost of a die of a single outer cover is more than 50 ten thousand RMB, and the cost of the single outer cover is also more than 3000 RMB, so that the overall cost of the antenna is very high, and the cost performance is not high.

US patent 9819094B2 discloses a lensed antenna system comprising a first column of radiating elements having a first longitudinal axis and a first azimuth, a second column of radiating elements having a second longitudinal axis and a second azimuth, and a radio frequency lens having a third longitudinal axis.
