Lightweight and mechanical design of carbon fiber reflector antenna for high frequency radar

As a kind of equipment for electromagnetic signal collection and transmission, the traditional antenna reflector of ship radar has increasingly stringent requirements regarding its weight on ships. The antenna system processes the received electromagnetic signal by feeding it to the receiving device and converts it into a visual form. Eventually, the result is saved to the workstation through the terminal system and exported after data processing in accordance with the specified operation. According to the geometric characteristics, when the reflector adopts a rotating paraboloid, the electromagnetic wave can be better concentrated at the focus position. Therefore, the antenna of the radio telescope is mostly of a paraboloid structure, and its reflective panel is mainly composed of metal mesh or smooth metal plate. However, the metal reflector is affected by the application effect of the material in the environment, and its resolution and sensitivity will decrease when the weight is large. Thus, how to ensure that the reflector antenna is lightweight for application in the responsive marine environment and can meet the requirements of the work is particularly crucial. In this paper, the reflector antenna is fabricated from carbon fiber composite material, and the application of the antenna in load and environment is designed accordingly.
