Self-Driven Deployable Conical Antenna

Abstract

The invention discloses a self-driven unfolding type conical antenna. The antenna comprises a rigid supporting mechanism, a flexible unfolding mechanism and a folding and unfolding mechanism; the rigid supporting mechanism comprises a bottom plate, a folding support, a skirt supporting ring and a conical cap; the folding support is installed on the upper end face of the middle of the bottom plate,the skirt supporting ring is installed on the upper end face of the bottom plate, and the conical cap is arranged over the folding support and is adjustable in height. The flexible unfolding mechanism comprises a belt spring, conical flexible cloth and a spiral metal wire; one end of the belt spring is connected to the upper end face of the bottom plate, and the other end of the belt spring is connected to the lower end of the conical cap. The edge of the bottom end of the conical flexible cloth is fixedly connected to the outer side face of the skirt supporting ring, the edge of the top endof the conical flexible cloth is fixedly connected to the outer side face of the conical cap, and the spiral metal wire is sewn on the cloth face of the conical flexible cloth in a spatial spiral linestructure; and the folding and unfolding mechanism is mounted on the folding support and used for controlling the change of the state of the belt spring. The conical antenna provided by the inventioncan realize self-driven unfolding from a folded state to a completely unfolded state.

Description

technical field [0001] The invention relates to the technical field of satellite antennas, in particular to a self-driven unfolding conical antenna. Background technique [0002] With the rapid development of science and technology and the modernization of people's life, higher requirements are put forward for the application of electronic technology, and many devices require broadband and sharing. Antenna, as a component for radiating and receiving electromagnetic waves, is an important part of a radio system. In line with the development trend of radio equipment, the research on antennas is becoming increasingly active. At present, the antennas carried on satellites are mainly conical antennas. As a typical broadband omnidirectional antenna, the gain of conical antennas increases with the increase in size, and is mainly the size in the height direction of the conical antenna. ; When using a rocket to transport and launch a satellite, if the conical antenna carried on the ...

Problems solved by technology

At present, the antennas carried on satellites are mainly conical antennas. As a typical broadband omnidirectional antenna, the gain of conical antennas increases with the increase in size, and is mainly the size in the height direction of the conical antenna. ; When using a rocket to transport and launch a satellite, if the conical antenna carried on the satellite is required to have a large gain, the size of the conical antenna needs to be increased, which will cause the satellite to occupy more launch space
