Abstract

The invention provides a light foldable rod antenna for aerospace, which comprises a rod piece main body, and is characterized in that the rod piece main body comprises a supporting column section (1) and strain energy holes (2) arranged in the supporting column section (1); and the inner hole wall of the supporting column section (1) is provided with a conductive layer (3). The rod piece main body is made by adopting a composite material system. The conductive layer (3) is a metal aluminum layer. The composite material system is made by adopting epoxy resin and carbon fibers. The high-performance rod antenna prepared through adopting a light carbon fiber composite material with high performance, adopting a foldable elastic strain energy structure and preparing the metal layer with excellent conductivity at the surface of the composite material can realize automatic unfolding, and substantially simplifies an telescopic control mechanism and reduces the overall weight of the antenna under the premise of maintaining effective receiving and emitting of electric signals.

Description

technical field [0001] The present invention relates to an antenna, in particular to a lightweight foldable rod antenna for aerospace and a preparation method thereof. Background technique [0002] At present, the rod antennas used in the aerospace field are generally made of metal materials in order to realize the transmission of electromagnetic signals. This type of antenna shrinks the antenna to the allowable volume through the mechanism when the spacecraft is launched, and expands it through the stretching mechanism after the spacecraft enters orbit. Since this type of antenna is made of metal material as a whole, there are many connection mechanisms to control the expansion and contraction, the overall weight of the antenna is relatively heavy, and the extension may not be in place during the extension process, and the reliability is low. Contents of the invention [0003] Aiming at the defects in the prior art, the object of the present invention is to provide a lig...
