Umbrella-shaped antenna reflector
An umbrella antenna and reflector technology, which is applied in the field of large-diameter and high-precision umbrella antenna reflectors, can solve the problem that it does not have high profile accuracy and profile retention capability, and the profile accuracy of the antenna reflector is difficult to meet the requirements. The loss of the effective reflection area of the antenna reflector can achieve the effect of simple and feasible structure, high profile accuracy and profile retention capability, and improved stiffness.

Embodiment Construction
[0045] The advantages of the present invention will be further elaborated below in conjunction with specific embodiments and accompanying drawings.
[0046] Such as Figure 1 to Figure 7 As shown in , the umbrella-shaped antenna reflector of the present invention includes a base 1, a fixed surface part 2, an expandable part, a mesh surface part 4 and a driving assembly. Such as image 3 and Figure 4As shown, the base 1 is a cavity structure, one side of the base 1 is fixed on the antenna support (not shown), the other side is fixed to the fixed surface part 2, and the edge of the base is between the two sides. The base edge is preferably a cylindrical edge or a polygonal edge. The solid surface part 2 is a solid surface reflector. The expandable part includes a plurality of expansion ribs 3, and the number of expansion ribs 3 can be specifically set according to actual conditions. The expansion rib 3 includes a top and a root, and the cross section of the root is greater...
