Study on Deployable Antenna Technology in Space

Abstract

Antennas play a pivotal role in modern communication, navigation, and remote sensing systems. With the development of space antenna, various kinds of deployable antennas have emerged. The deployable antenna can be folded into a small volume, significantly reducing the space and payload requirements for rocket launches. The commonly used techniques are inflatable deployable antennas, umbrella deployable antennas, memory alloy deployable antennas, and so on. Antenna deployment in the space environment, however, presents a unique set of technical challenges due to the harsh conditions of space, including microgravity, extreme temperatures, and radiation. A comprehensive overview of the current three distinct types of deployable antenna technology has been presented in this paper. Their characteristics, advantages, and applications are analyzed. Moreover, this paper also illuminates the numerous difficulties that scientists and engineers encounter while designing and deploying antennas, providing insights into potential directions for future advancement in this area. This paper may offer a reference for the development of deployable antennas.
