Description

Technical Field

[0001] This utility model relates to the field of antenna technology, specifically a high-precision reflector antenna. Background Technology

[0002] In modern communication systems, reflector antennas are widely used in satellite communications, radio astronomy observations, and radar systems due to their high gain and good directivity. With the continuous advancement of communication technology, the requirements for antenna performance are constantly increasing, especially in terms of accuracy, weight, and resistance to environmental interference. Traditional reflector antenna designs typically focus on improving electrical performance, such as gain and bandwidth, but often neglect the overall strength and lightweight design of the antenna structure. This makes the antenna susceptible to damage in harsh weather conditions (such as strong winds), and in large-scale applications, weight has become a bottleneck limiting its further development. Therefore, this invention proposes a high-precision reflector antenna. Utility Model Content

On the one hand, it employs high-strength, low-density novel materials, such as carbon fiber composites and aluminum alloys, as the main materials for the support frame to reduce weight while maintaining sufficient structural strength. On the other hand, in the antenna structure design, various reinforcing beams and support structures are introduced to disperse stress concentration under external forces, thereby improving the antenna's durability and stability.

A mounting hole for mounting a receiver or transmitter is provided at the center of the reflector. A windproof ring is arranged around the outer edge of the reflector. The support frame includes a central frame located on the outer periphery of the mounting hole. Multiple evenly distributed connecting beams are fixedly connected to the periphery of the central frame. An outer reinforcing beam is fixedly connected to the side of each connecting beam away from the central frame. A central reinforcing beam is also provided outside the outer reinforcing beam. The outer reinforcing beam, the middle reinforcing beam, and the windproof ring are connected by a second transverse beam.

The design of the above support frame structure can effectively disperse the stress concentration phenomenon under the action of external force and significantly reduce the overall weight. Moreover, the support frame is made of carbon fiber composite material or aluminum alloy, which further reduces the weight and improves the structural strength.
