A Large Two-Stage Foldable Circular Planar Antenna

Abstract

The invention discloses a massive two-stage foldable and deployable round planar antenna. The antenna comprises three layers in a radial direction. The three layers comprise an antenna plate core, antenna inner plates and antenna outer plates which are arranged from the inside to the outside. The antenna inner plates and antenna outer plates are distributed along the periphery of the antenna plate core, locations of the antenna inner plates and the antenna outer plates are in one-to-one correspondence. It is assumed that the corresponding antenna inner plate and antenna outer plate form a group of antenna modules. Two adjacent groups of antenna modules are taken as a group of deploying and folding modules. Each group of deploying and folding modules is mounted on a set of automatic folding mechanism. The antenna inner plates and antenna outer plates of two groups of deploying and folding modules in the deploying and folding modules are controlled to be folded and deployed through the automatic folding mechanism. Moreover, according to the adjacent deploying and folding modules, the adjacent antenna outer plates are connected through spherical hinges. The antenna inner plates and antenna outer plates of two groups of deploying and folding modules are folded and deployed, moreover, the antenna inner plates are folded and deployed, and the antenna outer plates of two groups of deploying and folding modules are folded and deployed. The antenna has the advantages that a shrinkage ratio is high, the working efficiency and space utilization rate are greatly improved, processing and maintenance are simple, the adaptive capacity is high, and the cost is low.

Description

technical field [0001] The invention belongs to the field of wireless communication, and relates to a planar antenna, specifically, a large two-stage foldable circular planar antenna. Background technique [0002] With the development of social electronic technology and space communication, smaller-caliber antennas can no longer meet the needs of wireless detection, electronic interference, and electronic attack radar antennas. Ground medium and long-range wireless detection, electronic jamming, and electronic attack military radars have widely used larger-caliber antennas, and are developing in the direction of high mobility and rapid response. The caliber of antennas for medium and long-range wireless detection, electronic interference, and electronic attack military radars on the ground is too large, so it is necessary to modularize the antennas to meet the requirements of transportation and debugging. If the large antenna cannot automatically expand and contract, the mo...
