Description
Technical Field
The invention relates to the technical field of communication antenna housings, in particular to a material and a manufacturing method of a light-weight 5G base station communication antenna housing.
Technical Field
The base station antenna is an important component of a mobile communication wireless access system, and is used for converting radio frequency electric energy fed back by a transmitter into electromagnetic wave energy or converting the electromagnetic wave energy into radio frequency electric energy and transmitting the radio frequency electric energy to a receiver. As mobile communication networks evolve toward 4G/5G, high quality, light weight, and integration of base station antennas are essential. The design of the base station antenna products is different, but the main structure of the base station antenna is composed of an outer cover, a reflecting plate, a feed network, an oscillator and the like, and the manual/remote electric tuning antenna also comprises a phase shifter.
Mobile communication puts higher and higher requirements on the structure and design of a base station antenna and the quality of key components such as internal electronic components, but the base station antenna outer cover plays an important role in ensuring signal transmission and protecting the normal operation of the electronic components. The 5G antenna is a device for receiving and radiating radio waves, and the radome is an outermost protective member of the antenna array. In order to obtain higher transmission rate than the 4G era, millimeter wave bands are adopted for 5G signals, which also brings the challenges of poor signal penetration and susceptibility to external interference. Since the antenna housing is a structure for protecting the antenna system from the external environment, it should have good electromagnetic radiation transmission performance and be structurally resistant to the external harsh environment (such as storm, ice, snow, sand, solar radiation, etc.), and the dielectric constant and dielectric dissipation factor of the material used as the antenna housing of the base station are key indicators. In addition, the base station antenna is placed outdoors for a long time, the working performance of the antenna system can be ensured to be stable and reliable by using the antenna outer cover, meanwhile, the abrasion, corrosion and aging of the antenna system are reduced, and the service life is prolonged. In addition, the antenna housing can reduce wind load and wind moment, reduce driving power of the rotating antenna, reduce weight of mechanical mounting parts, reduce inertia and improve natural frequency. Therefore, the 5G outer cover material has certain strength and rigidity, so that the outer cover material has better weather resistance when used outdoors, and simultaneously has excellent low dielectric constant, low dielectric loss tangent, stable required properties in a long-term use process and the like.
The current market is mostly 5G antenna housing made of the following materials: taking the radome made of the polyimide composite material as an example, the material refers to a military project scheme, and has ideal performance parameters such as dielectric constant, dielectric loss tangent and the like, but the cost is high and the material cannot be used in a large area. The epoxy resin prepreg has excellent physical properties, the thickness of the epoxy resin prepreg can be reduced when the epoxy resin prepreg is used as a 5G antenna housing, the dielectric loss tangent of the material is also reduced, but the dielectric constant is not reduced, and the weight is heavy, so that the high-altitude installation operation is inconvenient. The 5G antenna housing made of thermoplastic engineering plastics, glass fibers and other raw materials comprises a continuous glass fiber reinforced polypropylene composite material (CGF-PP), the signal loss is reduced compared with that of a conventional material, the wave-transmitting performance is excellent, the requirements of 5G communication on high frequency and low loss of the material can be met, but the weight is large, and high-altitude installation operation is inconvenient.
PVC and ABS materials are widely used in various industries due to their low cost, easy processing and wide material sources, the PVC/ABS composite material is widely used in the extrusion molding processing industry, particularly the application field of the material is greatly expanded along with the development of the PVC/ABS composite modification technology in recent years, the general PVC/ABS composite modification can improve the dielectric property, the mechanical property, the weather resistance, the mechanical strength and the processing property, however, although the common PVC and ABS composite modified material can meet the requirements of the 5G base station antenna cover on low dielectric constant, low dielectric loss tangent, weather resistance and the like, but has large density, heavy weight and inconvenient installation and transportation, so that the development of an optimized and improved PVC composite modified material is urgently needed to meet the requirements of various mechanical service performances, can simultaneously meet the requirements of low dielectric constant and low dielectric loss tangent, environmental protection and low cost.
