Background

In microwave communication, especially point-to-point microwave relay communication, applied to various natural environments such as mountains, deserts or coasts, faults tend to occur easily, and the best way to improve the stability and reliability of an antenna is to add a cover to the antenna, so that the antenna system is generally provided with an antenna cover. The purpose of the antenna housing is to protect the antenna system from wind, rain, ice, dust, solar radiation and the like, so that the working performance of the antenna system is stable and reliable, and meanwhile, the abrasion, corrosion and aging of the antenna system are reduced, and the service life is prolonged. Radio antennas are commonly used in mobile communication networks, such antennas comprising a main reflecting surface, typically having a concave surface, which may have a parabolic shape, which is axisymmetric with respect to the symmetry axis of the antenna, and feeding means, arranged along the symmetry axis of the antenna, for transmitting electromagnetic waves emitted or received by the antenna.
