The density of the glass fiber reinforced plastic pultrusion radome product for the 5G base station provided by the invention is 1.1-1.3G/cm 3 The dielectric constant is 2.8 +/-0.2 u, the dielectric loss is 5-10mu, the composite material is suitable for the construction requirement of a 5G base station, can meet the same performance requirement of a plastic antenna housing, and has better mechanical property, corrosion resistance and high and low temperature resistance than the plastic antenna housing. In addition, the glass fiber reinforced plastic pultrusion radome for the 5G base station is lower in cost, and the construction cost of the 5G base station is greatly reduced.
However, the following disadvantages still exist in the practical application process:
first, the production cost is high because the resin glue solution on the glass fiber is treated by the immersion method, which can ensure that the glass fiber is completely covered with the resin glue solution, but can cause serious waste.
Secondly, the quality is not good, because the glass fiber reinforced plastic antenna housing not only needs to ensure that the strength reaches the standard, but also needs to ensure that the wave-transparent rate reaches the standard, but the method in the comparison document is easy to have impurities in the environment to be merged into the interior of the glass fiber reinforced plastic antenna housing in the actual production process.
