Embodiment Construction

[0033] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0034] Such as figure 1 The flow chart of the installation of the metal mesh surface of the umbrella antenna is shown. It can be seen from the figure that an installation method of the metal mesh surface of the umbrella antenna includes the following steps:

[0035] Step (1), arrange n umbrella-shaped antenna ribs 3 outwardly with the same center; divide the umbrella-shaped antenna into n sectors, such as figure 2 As shown; the sector between the umbrella-shaped antenna ribs 3 is adjusted sequentially with a pre-customized sewing device 1 with high shape precision. The sewing device 1 is an arc-shaped fan-shaped bracket structure, and the sewing device 1 is made of aluminum Material. The adjustment method of the sewing device 1 to the umbrella-shaped antenna rib 3 is as follows: the sewing device 1 is placed in the sector between the two umbr...

Abstract

The invention discloses a mounting method of a metal mesh surface of an umbrella antenna and relates to the technical field of an antenna mechanism. The method comprises the following steps: (1) sequentially adjusting sectors between umbrella antenna ribs through a sewing device; (2), cutting a metal mesh; (3), levelling and laying the metal mesh on the surface of the sewing device, applying a pre-tightening force and fixing the metal mesh; (4), laying an L-shaped dielectric isolation belt; (5), placing and fixing the sewing device in one sector; (6), sewing the metal mesh and the dielectric isolation belt into two umbrella antenna ribs through a sewing thread; (7), repeating steps (3) to (6), and sequentially sewing n-1 sectors; and (8), adjusting the last sector, and repeating the step (3) to (6) to sew the last sector. The mounting method provided by the invention realizes the good electric performance requirement of the umbrella deployable antenna and ensures higher mesh surface accuracy and better tension uniformity.

Description

technical field [0001] The invention relates to the technical field of antenna mechanisms, in particular to a method for installing the metal mesh surface of an umbrella-shaped antenna. Background technique [0002] Since the umbrella-shaped deployable antenna has good electrical performance, it requires high mesh surface accuracy and good tension uniformity; it has a wide range of applications in the field of antennas. [0003] However, in the traditional sewing process of the umbrella-shaped expandable antenna, the method of manual hand sewing is basically used; this method has great disadvantages, as follows: [0004] (1) Uneven mesh surface tension; [0005] (2) There are large differences in the shape of the mesh surface of each sector; [0006] (3) After the mesh surface is sewn, the mesh surface tension is not within the reasonable range of the designed mesh surface tension. Contents of the invention [0007] The purpose of the present invention is to overcome th...
