The latest statistics from the Ministry of Industry and Information Technology show that as of the first half of this year, my country has accumulated more than 400,000 5G base stations, and the number is increasing at a rate of 15,000 each week.
As 5G base stations are usually installed outdoors, they are directly attacked by rainstorms, ice, snow, sand, and solar radiation. In order for the base station to operate normally, the radome is an indispensable part.
Radome
The radome is a structure that protects the antenna system from the external environment. In addition to the mechanical performance that can withstand the harsh external environment, it also needs the electrical performance with good electromagnetic wave penetration characteristics.
Since the antenna is the key to signal transmission and reception, the strength of the signal directly affects the quality of communication, and the presence of the radome will cause part of the electromagnetic waves emitted by the antenna to be absorbed and reflected, thereby reducing signal transmission efficiency. Therefore, the use of low-dielectric materials can make the radome strong in wave permeability.
In addition, the weight of 5G base stations has increased by 32% to 88% compared to 4G. Therefore, under the trend of 5G antenna integration, in order to avoid antenna hoisting to save installation time and cost, lightweight has become the basis for the design of the radome. At the same time, as people's awareness of environmental protection increases, the use of environmentally friendly radome materials has become inevitable.
LG Chem's ASA
With excellent weather resistance, the 5G radome manufactured by it is not easy to change color even if it is exposed to direct sunlight for a long time, and the changes in physical properties and appearance in extreme weather are also very small. Its dielectric constant is between 3.3-3.8, which can be as low as 3 after modification. In terms of electrical performance, it has high transmittance. At the same time, as a kind of recyclable plastic, it also has the characteristics of light weight and environmental friendliness.
At the same time, it has gathered so many advantages, it can be said that it is the "son of heaven" of radome materials!
