Description

Technical Field

[0001] The utility model relates to the technical field of antenna covers, in particular to a pultruded antenna cover with low wind load, low dielectric, low density and high wave transmission. Background Art

[0002] Generally, antenna systems are equipped with radomes. The purpose of the radome is to protect the antenna system from wind, rain, snow, dust, and solar radiation, so that the antenna system can work more stably and reliably. At the same time, it can reduce the wear, corrosion, and aging of the antenna system and extend its service life. However, the radome is an obstacle in front of the antenna, which will absorb and reflect the antenna radiation wave, change the free space energy distribution of the antenna, and affect the electrical performance of the antenna to a certain extent.

[0003] At present, most of the materials used to make antenna covers are materials with low dielectric constant and loss tangent and high mechanical strength, such as fiberglass, epoxy resin, high molecular polymer, etc. The dielectric constant of the materials is not adjustable. The structures are mostly uniform single-wall structures, sandwich structures and space skeleton structures. The design of the cover wall thickness needs to take into account the working wavelength, the size and shape of the antenna cover, environmental conditions, the electrical and structural performance of the materials used, etc. It is difficult to meet the high wave transmission requirements. Even under the condition of ensuring high transmittance, it does not have the function of large-angle wave transmission. Therefore, a pultruded antenna cover with low wind load, low dielectric, low density and high wave transmission is proposed. Utility Model Content
