Polypropylene microporous foam material (MPP), which is successfully prepared as a raw material for polypropylene, is applied to 5G radomes, opening a brand-new window of application, further enhancing the differentiation and high-end advantages of the product, and winning the market Provide strong guarantees. This breakthrough in the application field of special materials has also achieved new breakthroughs in the application of high-end new materials, improved the added value of special materials, and laid a solid foundation for building high-end brands in the industry.
It is understood that the role of the radome is to protect the antenna system from the external environment (such as wind, snow, sunlight, biology, etc.), extend the life of the antenna, and at the same time need to ensure the permeability of electromagnetic waves, so the radome material should meet the dielectric performance , Mechanical properties, weather resistance, processability and weight requirements.
While the low-dielectric and low-loss radome plays a protective role, the dielectric properties of the material will directly affect the performance of the antenna. The absorption and reflection of electromagnetic waves by materials will reduce the signal transmission efficiency. Therefore, materials with low dielectric constant and low dielectric loss are required for radome materials, and millimeter waves are more likely to be lost, so the dielectric properties of the materials are more demanding. high. At present, it is urgent to develop low dielectric and low loss materials for the radome.
Lightweight radome materials are usually fiber-reinforced resin composite materials. At present, radomes are mainly made of glass fiber reinforced plastic, but the proportion of glass fiber reinforced plastic is large, which is not conducive to the lightweight design of the antenna. The new material of the radome is GFRPP, which is super strong glass Fiber-reinforced polypropylene resin is 40% lighter than traditional glass fiber reinforced plastics, controlling the weight of multi-band antennas within 50 kg, avoiding antenna hoisting to save installation time and cost. This shows that in order to meet the design requirements of 5G antennas for light weight, integration, and miniaturization, radome materials will also be developed towards light weight.
Environmental protection In recent years, as people's awareness of environmental protection has increased, the requirements for environmental protection at home and abroad have become higher and higher. The environmentally friendly type is 5G.
Faced with the higher requirements of 5G for radome materials, companies actively research and develop materials with high cost performance, environmental friendliness, light weight, low dielectric and low loss enhancement, such as ASA, PP, PC, etc. These materials It is expected to be applied to the future 5G radome.
