Modularization planar antenna of ordered expansion of inflatable driving

Abstract

A modularization planar antenna of ordered expansion of inflatable driving belongs to the space-borne antenna technology field. The problem is solved of the existence of the current Z-shaped folding bar-shaped planar antenna. The antenna comprises a Z-shaped folding antenna panel formed by hinging from head to tail in order of a plurality of plane signal receiving and dispatching modules, support arms are respectively arranged along the edges of two sides, perpendicular to the joint, of the antenna panel, the support arms employ flexible gas tubes, and the support arms are configured to bond the connection cloth which coats the support arms with the antenna plane; and one ends, at the same side, of the two support arms are provided with end caps, the back of the antenna panel is provided with a truss, the truss is formed by bonding a plurality of the flexible gas tubes, the positions corresponding to joints of the antenna planes in the support arms are provided with flexible separation blades, the diameters of the through holes on each flexible separation blade gradually become small from one end provided with the end cap, and the position corresponding to each plane signal receiving and dispatching module at the surface of the connection cloth coating the support arms is provided with nylon thread gluing. The modularization planar antenna of ordered expansion of inflatable driving is used for a space-borne platform.

Description

technical field [0001] The invention belongs to the technical field of space-borne antennas, and in particular relates to an inflatable driven and orderly deployed modular planar antenna. Background technique [0002] The spaceborne platform has strict restrictions on the weight of the antenna and the volume of the initial launch state. Therefore, in order to meet the needs of launch and reduce the cost of launch, the structure of the spaceborne antenna should have the characteristics of high storage ratio, light weight and expandability; Z-shaped folding The strip planar antenna is a modular antenna in series, which has a smaller storage ratio than other structural antennas and can better meet the needs of aerospace; the existing Z-shaped folded strip planar antenna with multiple boards in series is mechanically or Strain energy deployment, in which the mechanical deployment effect is stable, but due to too many mechanical joints, heavy weight, low deployment reliability, l...

AI Technical Summary

Problems solved by technology

[0005] The beneficial effects of the present invention are: adopting inflation pressure to drive deployment can solve the series reliability problem of mechanical drive deployment methods such as pyrotechnic device unlocking and torsion spring drive, and can also solve the problem of low fundamental frequency, improving the anti-interference ability, Moreover, there are no mechanical joints, light weight, high storage ratio, and can be unfolded in an orderly manner. After unfolding, the precision is high and the stability is good.
