Cable-net antenna, metal mesh structure for cable-net antenna and manufacturing method thereof

Abstract

The invention relates to a cable-net antenna, a metal net structure for same and a making method thereof, and belongs to the antenna cable net structure technical field; the cable-net antenna uses themetal net structure that includes a metal net and matching lines, wherein the matching lines are arranged on a reflection surface of the metal net; the metal net structure also provided with at leasttwo matching line fixed points corresponding to cable net nodes; the matching line fixed points are fixedly connected with the metal net; the portion, besides the fixed points, of the matching line is connected with the metal net, and the relative position of said portion can change in a preset scope; the matching line is tightened in an application state. The radial rigidity of the matching linecan resist metal net anti-pillow effect; the metal net structure is simple and easy to form, thus highly stably improving the antenna profile precision without adding cable net node quantity, and preventing the problems that the antenna adjusting work is increased along with the increasing cable net nodes and that the antenna adjusting efficiency is reduced.

Description

technical field [0001] The invention relates to a cable-net antenna, a metal mesh structure for the cable-net antenna and a manufacturing method thereof, and belongs to the technical field of antenna cable-net structures. Background technique [0002] see figure 1 , the cable-net antenna generally includes an antenna structure main body 1 , a cable-net system 2 and a metal mesh 3 which are fixedly connected in sequence. Depend on figure 1 As shown, taking an umbrella-shaped deployable antenna as an example, the antenna structure main body 1 is mainly composed of several antenna ribs, feed source and support structure, secondary feedback and support structure, etc. After successful deployment, the lock is completed to form a stable structural system; The cable net system 2 is mainly composed of flexible tension ropes, which are connected to the antenna structure main body 1 in a certain way, and the required antenna profile is formed through design, such as figure 2 As sh...
