Parabola antenna
Parabola antenna is an important part of the antenna. Usually, a metal rotating parabolic surface, a cut rotating parabolic surface, or a cylindrical parabolic surface was used as a reflective surface. There were certain requirements for the material of the reflective device: 1. ** Conductivity **: Must have good electrical conductivity to ensure effective reflection of electromagnetic waves. 2. ** Surface smoothness **: The surface should be as smooth as possible to reduce scattering loss during reflection. 3. ** Weight **: For antennae that need to be moved or installed in special locations, the weight of the antenna is an important factor. 4. [Weatherability: Requires good weather resistance and long-term stability in various climates.] 5. ** Cost **: Material cost and processing cost are also important considerations. The common materials for the mirrors were as follows: 1. ** Metal Material ** - [Aluminium-type material: One of the most commonly used materials. It has good electrical conductivity and machinability, and the cost is relatively low.] - Copper: Its electrical conductivity is better than that of aluminum, but it costs more. It is usually used for applications that require extremely high reflective efficiency. - ** stainless steel **: has good corrosion resistance and mechanical strength, suitable for outdoor applications, but the cost is higher. - ** Metal coating **: For example, the surface of aluminum or copper is plated with silver to improve reflection efficiency and reduce loss. 2. ** Compound Material ** - ** carbon fiber composite material **: lightweight and high strength, suitable for applications that require weight reduction, such as the antenna on spacecraft. - Glass fiber reinforced plastic (fiber reinforced plastic): Low cost, good weather resistance, but reflective efficiency is not as good as metal materials. 3. ** Coat Material ** - Metal coating: For example, a thin layer of metal, such as aluminum or copper, is plated on the surface of a plastic or composite material. - ** Conductive paint **: A paint containing metal powder, coated on the surface of the reflective device, suitable for low-cost and fast installation applications. In different application scenarios, the choice of the reflective material needed to consider a variety of factors: 1. ** Conductivity and loss **: The better the material's conductivity, the higher the reflection efficiency and the lower the loss. Copper had the best electrical conductivity, followed by aluminum, but the cost of copper was correspondingly higher. 2. Weight and stability: For antennae that need to be moved frequently or installed in specific locations (such as satellites or airplanes), lightweight materials such as carbon fiber composite materials are a better choice. 3. ** Weatherability and maintenance **: The antenna that works in harsh environmental conditions needs to be made of materials that are resistant to corrosion and ultraviolet-light to reduce maintenance costs. 4. ** Cost-effectiveness **: Considering the performance and cost, choose the material that is most suitable for the specific application. 5. ** Usage environment **: Wind pressure resistance, corrosion resistance and other factors need to be considered for outdoor applications; more cost factors can be considered for indoor applications. 6. ** Range of frequency **: The performance of the material is different at different frequencies. You need to choose the appropriate material according to the working frequency. 7. ** size and shape **: For a large antenna, the mechanical strength and stiffness of the material may need to be considered; for a small antenna, the weight of the material may be more important. For example, satellite communications usually used aluminum alloy or carbon fiber composite materials to ensure lightness while ensuring sufficient mechanical strength; the large radio telescope in radio astronomy often used aluminum alloy or stainless steel to ensure good surface smoothness in large size; the miniaturized parabolic antenna of mobile communication base stations may use metal coating or conducting paint to reduce costs. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
