Abstract

The invention discloses a modular planar antenna, belongs to the technical field of a space-borne antenna, and solves the problems existing in the current Z-shaped foldable strip-shaped planar antenna. The modular planar antenna comprises a Z-shaped foldable antenna panel which is formed by a plurality of planar signal transceiving modules hinged in an end-to-end manner in sequence; a supporting arm is arranged on each of the two side edges, perpendicular to corresponding connecting seams, of the antenna panel separately; the supporting arms adopt flexible gas filled tubes; each supporting arm is glued with the antenna panel through a piece of connecting cloth for coating the supporting arm; end covers are arranged at one ends of the same side of the two supporting arms; a truss, which is formed by a plurality of flexible gas filled tubes in a gluing manner, is arranged on the back surface of the antenna panel; a flexible baffle is arranged in a position, corresponding to each connecting seam of the antenna panel, in each supporting arm; and the diameter of a through hole in each flexible baffle is gradually reduced from one side of the end cover. The modular planar antenna 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 a 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, low fundamental frequency, and low fundam...
